Dinosaurs evolve, become the most diverse group of terrestrial vertebrates on the planet, and are then almost entirely wiped out except for a single lineage (or rather three closely related lineages) that then quickly expand to become the most diverse group of terrestrial vertebrates on the planet once again, because you can't stop a dinosaur from being awesome.
That my friend, is true
Archaeoraptor liaoningensis
When National Geographic published the first pictures of a fossil creature that looked for all the world like a bird-dinosaur, it was hailed as a stunning coup. But now the creature has been exposed as a hoax--the latest in a series of embarrassing reversals in evidence for evolutionary theory.
...
Boy, it's a good thing Timothy Rowe, Phin Currie, and Xu Xing, paleontologists, familiar with evolutionary biology, who were listed as co-authors on the paper that described "Archaeoraptor," determined that the specimen was actually a composite of Yanornis, a bird with clawed fingers on its wings, and Microraptor, a dinosaur closely related to Velociraptor, which had birdlike wing feathers on all four of its limbs which were clearly adapted for gliding (also described by Xu Xing), which had been cemented together by the farmer who discovered it before it was illegally sold to enhance its value, and also that the paper that it was rejected from the scientific journal, "Nature," and the press release was only distributed in the popular magazine, National Geographic, and not an actual, formal journal. Stephen Czercas, the main author of the paper, admitted that he had made, quote, "an idiot, bone-stupid mistake." It's a good thing we have hundreds of specimens of Microraptor, as well as other genera like Anchiornis, Confusciusornis, Sinornithosaurus, Zhenyuanlong, Archaeopteryx, of course, and many, many others, which fill in basically every step between small nonavian theropods and modern birds, to the point where "bird" has become a meaningless informal word and we actually have no idea where "dinosaurs" end and "birds" begin anymore. We confuse avialans for troodontids and dromaeosaurids for avialans all the time. That's how seamless the fossil record between these groups is. Gosh, I'm so glad we figured out that "Archaeoraptor" was a composite, otherwise that would have been really confusing, right?
Right, an old friend of mine was an archaeoraptor, the last time i saw him was 2 years ago.
Is that why some chicken nuggets are shaped like dinosaurs? Did we always subconsciously know this?
i cant handle this level of comprehension. i think we need to go deeper
Woah
Oh my god...
David McMillon wtf😂
thats what i thought.
I wonder if T-Rex meat tasted like chicken? lol
I bet it did.
Go back and try to it flesh
Florida chicken, alligator steaks.
I don't think that's how evolution works. T-Rex probably evolved into a larger and much heavier bird which has now been extinct for hundreds of years due to human activity.
Maylee Cao the T-Rex got extinct way before that.
Other dinosaurs evolved into birds, and they were also theropods.
T Rex dying in the asteroid impact to all the tiny therapods: "Fly, you fools!"
My mini-dinosaur, called a parrot, talks to me every day. Not only did dinosaurs miniaturize, but they also evolved 4 chamber hearts and big brains. My companion parrot loves his human companion in today’s modern world. Imagine, what non-avian dinos would have evolved to, along with small, diminutive mammals. Pretty fascinating to say the least.
Imagine if, instead of mammals evolving giraffes, thinner sauropods evolved into their niche
Extinct not extont
So what your saying is when I’m eating dinosaur chicken nuggets I actually am eating dinosaurs
barbarian! 😢
Technically Yes
birds went from monstrous creatures to cute small feathery creatures
+Karina Jimenez Chable what
***** i know that
dinosaurs are not monsters
welp i don't find dinosaurs that scary
People just ate the big ones first because they were easier to catch and more meat.
Kentucky Fried Dinosaur.

I'll have a drumstick & that'll do for the next year or so......
Birds are dinosaurs in the same way that bats are mammals.
Basically, imagine that a meteor wipes out all mammals except bats, and they're discovered by aliens. Would it make sense for them to say that bats are "descended" from mammals, or that they *are* mammals?
That's a pretty smart comparison, I actually think whales and dolphins are a better comparison since it's suprising to discovered they share the same ancestors with other mammals.
+sam rizzardi Cladistics is weird. Birds are reptiles, and so are mammals... technically. Reptiles are amphibians... Amphibians are fish. We have tried to group animals by characteristics, but cladistics says "screw that".
Well, there's a difference between monophyletic and paraphyiletic clades. Paraphiletyc clades emphasize characteristics of a group of animals while monoplyletic clades are based on one single ancestry with different branches. 'Fish' is a paraphyletic word since it excludes all terrestial animals that descended from fish.
Sandro Algra Barradas So wouldn't reptile also be a paraphyletic word?
Also, I was reading more about mammals and if they were ever reptiles. That's... a weird discussion too. It seems that they evolved from things that were not quite reptiles but were past being amphibians.
Meghan Pierce
That depends on how the word reptile is used. If you make a clear dintinction between reptiles and birds... then yes, you're using the word in a paraphyletic way. But 'reptilia' is also used as an official taxonomic name. It includes all animals that belong to the family of 'true reptiles'. This includes dinosaurs and therefore birds. So taxonomically speaking birds are also reptiles.
Mammals are not reptiles. Although our ancestors were at some point very reptilian in appearance, they weren't true reptiles. Mammals belong to a group called the synapsids while reptiles belong to a group called the sauropsids. But both groups do belong to a larger family called the amniotes.

Yes!!!!! I have chickens and I always thought they looked like tiny dinosaurs! Also my rooster makes a strange dinosaur-like noise
There is so much ignorance in this comment section denying evolution.
I love Dinosaurs, both modern day and prehistoric.
I remember hearing about the whole dinosaur to bird idea in some freshmen college class, way back in the fall of 1989. Back then, if I recall correctly, my professor was telling us about recently studied similarities in the anatomical vocal structures used by both birds and dinosaurs. Also about evidence indicating possible/probable warm-bloodedness in dinosaurs?
Birds evolved. That is crazy talk. Sprouted wings one day and were breeding gold to the girls. That is hilarious. Only colleges in the last 50 years can talk brazenly stupid. Even college is proof of de evolution.

How did dinosaurs evolve into birds? The important question is, how to we reverse the process to the point where we can ride a Velociraptor to work or the grocery store?
A velociraptor is about 2 feet tall. Unless you are infant you would likely crush it.
Umm birds do have scales look on there feet
It is true that birds came from dinosaurs. But not from all. Only a clade known as Maniraptora, which includes oviraptor, velociraptor etc, evolved into birds. There are many other dinosaur clades,tribes and families such as Marginocephalia(Triceratops), Sauropoda(Brachiosaurus) and Tyrannosauridae(Tyrannosaurus), that were ultimately gone extinct. From Maniraptora evolved species like protarcheopteryx and archeopteryx, the first birds. What i want to point out is that, you can't say dinosaurs are still alive, because the only living dinosaur class at the end of Cretaceous evolved into the first bird class (Ave). It is like saying that since there are cats, smilodons still exist.
AnimalLover Dinosaurs with scales? Did Jurassic Fart teach you that like it taught you the Velociraptor's size? Of course some dinosaurs didn't live in herds, because not all dinosaurs evolved to birds. The Velociraptor is the closest thing you get to a bird, as Dromaeosaurids branch off the group that contains such creatures as Archeopteryx. Different toes? Sorry to shit on your comment, but a T-Rex foot is shaped EXACTLY like a chicken foot, one longer finger in the middle, two similar fingers and a weak toe on the back. Chickens develop teeth to pluck out insects? Then why don't they grow them normally? Chickens pluck out insects a lot of the time. And OF COURSE birds will look drastically different from dinosaurs idiot, it's 65 million years of evolution, 10 mil. years less than it took primates to appear and form into man.

Diplodocus lived in the jurassic period it would never face the CT extinction event.
Thank god them saying that annoyed me so much. Thanks for saying this
ok
Na I found one last week.
fred bitzaya In fact we live closer to the CT extinction than Diplodocus did
fred bitzaya yup.
Theropods aren't a family of dinosaurs but a suborder. I know it's nitpicky but I just had to point that out :D

Who needs a Turkey dinner when you could have a t-Rex dinner
Nia LaLa I have a brain and have health issues and was ordered by my doc to eat meat because of said issues. Usually a smaller stake or chicken breast with the occasional fish thrown in for good measure. You can be vegan or vegetarian all you like, just don't be a bitch about it.
letsgetthisoverwith Please don't take it the wrong way, but while I do know of some health problems which could be helped by eating meat, I don't know of any which would actually require you to.
***** What's ironic about this argument is that you can't make it without being judgmental yourself.
Nia LaLa Actually, vegetarians are still a small minority and there are lot of people who eat meat and who happen to be very smart, even though I agree with you that they are wrong to do it.
Oh I'm sorry but were do u get your animal proteins from? Pills, still animals.
I have always wondered how fast a species could stunt their growth... Or like how fast a species could go from being big to small and still be a relatively healthy species?
When a bird walks or runs, I think that looks like a dinosaur running, from certain angles
Someone once attached a piece of wood to their tail to mimic a non-avian dinosaur tail, and it made them walk even more dinosaur like.
Me: *eating chicken, moment of realization*... holy crap....Im eating a trex
While you have a lot of things right, I do want to point out that dinosaurs that directly evolved into birds did not shrink. From the Triassic to the KT event, they were always been small, no bigger than a house cat.

"Less body means less to take care of, means survival."
Then why we needed to grow bigger than our ancestral forms, bacteria?
PinGsamY Those are just words we invented, we love to play and we play with words too, dont take words to serious. The universe doesn´t work in our language : x So it´s just a word play not a rule of the universe : D
PinGsamY because coming together making it easier to survive = good.. apparantly coming together past the form of bacteria was really beneficial... kill the other guys that has more food then ourselves,,,, or just create a new source of food.. bacteria (the cells themselves eating eachother means there is more food around meaning more energy to waste making better versions of future you! i'm sorry it's hard to explain... basically.... bacteria found that killing family = food... the food then evolved into eating previous family... then they evolved to eat the first evolution! the race went on!....
Because that never happened
sure it did and im riding an ice dragon who's spitting out rainbow ghosts
Soulplexxis Watch out for talking snakes and giants.
Not "all" dinosaurs had feathers. It's speculated that almost all avian-dinosaurs (theropods) had feathers but the non-avian like sauropods (longneck), ceratopsian (like triceratops), Iguanadon and most quadrupedal dinosaurs would have had the rough leather/scaled skin
There's also Carnotaurus, a theropod that has scales instead of feather, and almost snake-like jaws.
You should read more news.. new study shows dinosaurs has scales. Not feathers.
To be more clear on the subject, some dinosaurs only had scales, some dinosaurs only had feathers, and others (including BIRDS) have both.
@@gibsonflyingv2820 you're right
Yes thank you finally! The argument that ALL dinosaurs had feathers is stupid. Yes a lot of dinosaurs had feathers, but only scale impressions have been found with the t rex, triceratops, stegasourus, brachiosaurus, etc
see the living bird cassowary, you'll believe dinosaurs existed and were related to birds
nope, I think they are more related to lizards. Look at flying species of lizards..they had wings too. Crocodiles & aligators basically haven't changed at all...and large monitor lizards and dragon lizards like the komodo dragon resemble more dinosaur like qualities than birds. Birds aren't the only animals capable of going underwater, so can reptiles!
Modern lizards and snakes are part of the family of animals called Lepidosaurs, a family of reptiles that split off from Archeosaurs like Crocodilians, Pteosaurs, and Dinosaurs. Dinosaurs and Crocodiles are part of the Thecodont branch of Archeosaurs.
ok makes sense now, cool thnx
GrowingDownUnder dinosaurs are distantly related to lizards. dinosaurs never looked and looked nothing like lizards.
Emus are like dinosaur as it comes. Goats too. Look at their anatomy its crazy. Their eyes horns hooves. How do you just grow horns unless you always had them? I understand losing them through genetic errors. But gaining appendages or extra bits is a far stretch unless some gene splicing or cross breeding of species occurs. If evolution is a real thing then ADD kids are a new breed made to cope with the 100mph instant information sugar caffeine work to death life we have. But evolution can only make so much sense. With out some creatures in the food chain there is no food chain which means death. From mites and microbes to mammals and pachyderm things have been around longer than their remains are able to exist. There is no evidence of the mould under the sink once you clean it, even less if you rip it out put in a new sink and infinitely less once the old one has been in an incinerator or landfill. There cant be evidence of anything past a certain point as reality dictates the most you can get is a fossil which can easily be misconstrued confused damaged or destroyed. Sadly word of mouth and man made stories and myths have more evidence than reality itself. We outlive outlast and overcome through rebirth, the same as all of nature's creatures until we destroy them. We also seem to be the only creature on Earth capable of bringing them back. So that gives more credence to the God Theory. If we now have the power to create life and destoybit have we not become gods. Have we not proven the Gods right and we are able to be in their image on earth. That we have now gone full circle and created a virual reality inside our own reality which people are as gods even more so. Access to contact speak and be everywhere at any time, all information knowledge and everything at our will. But through interbreeding and even minor gene manipulation we have so far only had mutants not evolution. Cancer not a new appendage. Diseased rather than flourishing. But if we just did full gene editing we could have giants and monsters with human brains/minds. How is that any different than the original God stories? Not the made up a few thousand years back ones. The original story of the Gods made us from earth DNA found in the dirt. We are an extinct species reborn. That is why we didnt evolve. We were one of many types of bipedal creatures who had brains and families and mated with other bipedal creatures till we had a breed to kill off the others and survive this earth. Look at humans and then look at other animals etc. We have no offensive bits, no natural anything. Our teeth are mixed our bodies weak but able to become strong. We are pets.
Dinosaurs taste so good!

True evolution:
Dinosours to chickens to dinosour shapped chicken nuggets
I know birds decend from dinosaurs, but im sick of the media stereotyping that they came from trex. true they came from the tharopod line but these evolution occurred long before trex. Auronis and later archeopterex skelotonwise looks like a dinosaur. then by the early cratatious birds have aready be fully formed with functional flapping wing instead of gliding wings like arche. by the time of the KT event birds have already takken the place of pterosaurs.
Someone finally fucking said it. That's a huge nitpick for me as well. T. rex wasn't involved in this idk why they keep mentioning it.
I... don't recall him saying birds came from dinosaurs. I could have sworn he said birds came from theropods, one of type of which are the tyrannosaurids...
they are cousins of t-rex, as were all other theropods!

This guy's hair is evolving into feathers. :)
Why is D News, a science channel, inappropriately using "theory" for the word "hypothesis"?
Because evolution is not a hypothesis, it's a fact. :)
nicole miarey lol Darwin's theory on evolution has a tonne of flaw's but its's the most accepted theory, nothing is fact lol
airman122469 Darwinian evolution is not a fact.
You just answered it yourself, you mentioned two different things. How can it be the same? If it was all the same thing wouldnt it just be classified under the same title?
blaze46waffle Who said anything about Darwin's version of the theory of evolution? Evolution is a scientific theory, arrived at by over 100 years of study. Darwinian evolution is not the complete theory, but it is a good starting place to explain evolution. Evolution happens all the time. Viruses, bacteria, drosophila (fruit flies), nematodes, and more, have all had observed speciation events. Evolution is a fact of non-perfect replicating systems. We can even simulate biological evolution with some relatively simple software. All it takes is a mutation rate and a fitness factor to select "most fit" individuals.

he said small dinosaurs survived the mass extinction and evolved into birds
here were already birds in the cretaceous...
yeah, t-rex became chicken.
no.
T-Rex became piles of bones.
I just had an argument with a guy about whether birds are Dino's and it somehow ended with him telling me I'm not man enough to have prostitutes 😂
Lucky The Dog that happens alot
I have been 'down with it' for more than 40 years. As a kid, I was reading a book that showed the skeleton of a pigeon and a skeleton of a similar shaped dino. The writer of the book was trying to illustrate the differences between the two but I was completely unconvinced. I distinctly recall saying, "It looks like a bird to me"
Fossils only prove that such an animal existed. It doesn't show who it's ancestors were or who it's kids were. Similarities don't prove ancestry. That would only be an assumption based on the assumption that one type of animal(dinosaur) can change into another(bird).
I love bird watching so now So now I love dinosaur watching! My hobby is dinosaur watching!
Imagine telling people that your hobby is dinosaur watching. lol
I should not have looked at the comments. I should have watched the video, said, "Hey, I already knew this, but it's still pretty neat," and moved on.

There size was due to atmospheric oxygen concentrations, Don't know about the "Every Dinosaur had feathers" thing yet as crocs and lizards do ok without that today :)
The size of the larger dinosaurs came from the need to eat the taller trees and kill the bigger herbivores. When the asteroid wiped out the presence of the sun for a few decades, large size was not advantageous anymore and anything bigger than a medium sized dog *on land* died out. Sharks and such were perfectly fine up to the four meter range.
A difference between dinosaurs and reptiles is that dinosaurs (as determined from the presence of birds) were warm blooded. They relied on internal heat to stay warm, whereabouts reptiles relied on external heat to stay warm (eg the sun).
Now oxygen concentration would be much more plausible if you were arguing for the sake of giant *insects*, as modern insects don't actually have lungs, and are limited in size because of their trachea works on simple diffusion rather than creating a vacuum (as anything with a lung uses). However, giant insects were around with lower than Carboniferous Forest level oxygen concentrations, so quite possibly there might have been insects with lungs.
Both crocodiles and lizards predate theropod dinosaurs, so its entirely likely many of them did sport some fluff. Also the sister group to dinosaurs, pterosaurs had pycnofibres(basically fur).
Physics has crunched the numbers and said that a dinosaur's bones would break under their immense weight. However the thick atmosphere theory was proposed. Basically the gasses 65 million years ago were very thick. The pressure would be like going very deep into the ocean. This adds buoancy and makes it completely possible for them to grow to that size. Another theory I heard was there was less gravity. But I think I heard that from Jose Canseco.
The Lost History Channel TKTC Crocks and lizards are reptiles..... Dinosaurs where not....
Jayme Lawton correct
I found this video just as my wife had been asking if any herbivorous dinosaurs could have evolved as we already knew the theropods did. Glad you answered that one!
When a bird sings a conversation
They sound a lot like us
And analyzing it can be fun
As they really make a fuss
Those very intelligent crows you see
Are the most obnoxious ones
They talk loud and out of key
So therefore they're like humans
Some birds sound very pretty
But they really don't sing loud enough
And that is like some people, we
Do not pay attention much
Some birds are absolutely stunning
To looks at with your eyes
But when they open up to sing
They only make hoarse cries
So that mean when vegetarian will die off before the meat eater lol
+Jazneo Gaming yeah because even in the end of the world they refuse to eat meat
+Jazneo Gaming Yes it mean that
We will eat meat and even slaughter animals... the thing is that it's not necessary at this time.

Aug 12 1953 - The first testing of a real thermonuclear weapon (not test devices): The Soviet atomic bomb project continues with the detonation of "RDS-6s" (Joe 4), the first Soviet thermonuclear bomb
Aug 12 1977 - The first free flight of the Space Shuttle Enterprise.
Aug 12 1981 - The IBM Personal Computer is released
I have this thought since i was child. When i had many chicken in my backyard. 'Why those chicken looks like dino? do birds/chicken is the giant dino in earlier earth life?' Now i have the answer. Thanks to scientist
dude chickens are the king of the forest (T Rex)
Haha really Foxy best
Vegetarians you better start eating meat...
Too bad humans humans cannot properly digest meat and because of that has lead to the two leading factors of death in the united states
I eat nothing else than Meat, Fish, Eggs and nuts(jokes free pls) and... my health is soooo awesome~~~
PurpleRaven300 This also happens with plants.
death or become a tiny meat eating bird hhhhmmmm that's a hard one and I don't really want to be a copy cat
sarfios i wouldn't even bother. vegans and vegetarians will ignore facts that go against their beliefs. arguing with them is useless.
Being called a chicken won't be an insult anymore.
Your voice is really good.🤣You should do more of these videos.
birds began to evolve before mass extinction
one of the reasons they are currently classified as dinosaurs.
yeah..Dinosaurs were there all the time..right in front of our eyes....we just didn't recognize them in their current avian form....funny...we called them Birds.....I remember over 30 years ago when this was first coming to light...back then ; many thought that crocodiles were the dinosaurs closest relatives...not birds....how wrong they were....Birds are dinosaurs....I believed that 30 years ago...good to see the world is finally discovering the truth....though I'm sure you will always have your disbelievers ; and those not ready to accept that fact....yeah look at me like i'm crazy; if I call them Dinosaurs....skeptics....I know the truth.
@@davidsnyderWisdomTrollBlocker hahha Evolution fairy tale...
Thank you SO much!! This helped me with my school project and I’m hoping to get at least a B! This information really helped! 🙃
Fact. The budgerigar (parakeet) had survived harsh inland conditions for five million years. Several of these hominins used fire, occupied much of Eurasia, and gave rise to anatomically modern Homo sapiens in Africa about 315,000 years ago.
It's true, Birds are descendants of dinosaurs
They also are dinosaurs.
I love how they want to be soooo accurate in paleontology, but they drop in the MOST inaccurate footage of dinos
Or, maybe since gravity is just a theory, some idiot dinosaurs trying to prove that it's not real jumped out of a cliff, and as everybody knows the bigger you are the harder you fall, the opposite must be true too : the smaller you are, the softer you fall.
And thus, smaller dinosaurs survived the gravity experiment.
As for the flying part, one of the smaller dinosaurs lost a parent in the experiment. Devastated by sadness and anger, he spat those historical words in the face of the universe : "Screw gravity!" and took off.
Someone give this man a Nobel Prize.
So I guess technically everything taste like dinosaur...baby t-rex to be exact, lol.
I believe I recently read not all dinosaurs had feathers, only a few select types. This includes the Theropods, of course.
Yes absolutely correct
The Dino nuggests speak the truth !!!
Raptor means.. bird of prey
No. It means thief. Velociraptor= fast thief.
It doesn't look very scary.
More like a 6 ft turkey.
:D
it means both.
Dalek Renegade a 2 feet turkey.
Why y'all billing me
Birds "are" dinosaurs.
lol that opening intro. it's the best one i've heard haha
so when you think someone is being a chicken, acting scared or what have you... you can tell them "don't be a dinosaur" and confuse the shit out of them
Imagine if the T-Rex sees what we are doing to their descendants or the chickens in factory farms and how it will react.
1. T. rex
2. Birds are NOT descended from T. rex
There are no known evolutionary descendents from the T. Rex. They were merely a part of the theropod group of dinosaurs, which contained other species that eventually evolved into birds.
All I wanna know is how many of those 2.2 million subscribers don't realize that this channel is not affiliated with Discovery
Very nice

God I love it
So birds are reptiles
You can say that. Or, even better, all reptiles are birds ...... deep.
No. Birds evolved from reptiles and became... birds.
Common now, no need to be so literal. We all get it. If we're gonna be literal , lets just ditch the word reptile, cause not all dinosaurs were cold blooded.
No.... he was talking about only a small species of dinosaurs called Theropods that evolved into birds. Other species evolved into reptiles as well.
Monophyleticly speaking, birds are reptiles, but that would also make mammals be reptiles and would make birds, mammals and reptiles all be fish. Sometimes a group has to be defined paraphyleticly for it to be useful in common language. Observe this diagram of a phylogenetic tree that excludes mammals and aves[birds] from its group of reptiles. en.wikipedia.org/wiki/Paraphyly#mediaviewer/File:Traditional_Reptilia.jpg
So the dinosaur era 🦖 was really the giant bird era 🦅
White Tip from Planet Dinosaur at 2:27
Uh is this a this a reference to the Big Bang theory because if it is it's not tru
MegaBrame Did your mom homeschool you?
Mikes8899 LMAO 😂 I was legit gonna say that.
N O C O R R E L A T I O N
Love when they do stories like this so I can sit back & scroll through the comments & laugh at the religious nuts
Bla Bla Bla Bla Bla.. Hence it is proved birds evolved from dinosaurs
@@upworkqureshi6665 proofs it
Evolution is fairy tale..
@@upworkqureshi6665 yes it is a fairy tail and evolution is fake
@@indoraptor3405 yes clearly evolution is fake but your magical fairy man in the clouds is totally real
Raptor literally means Bird of Prey. How fitting.
Dromeosaurs all died out. Birds predate dromeosaurs [like velociraptor].
Birds and mammals evolved in the Jurassic, most famous dinosaurs you see in movies evolved tens of millions of years later during the cretaceous.
it's not that all dinosaurs *had* feathers, it's that any *could*, the ancestor lineages all had feathers, meaning any dinosaur had the possibility to have them, some couldve, and wouldve, secondarily lost their feathers
Yes, protofeathers may have predated dinosaurs and been rooted earlier in archosaur history. We still don't know for sure if pterosaur ''fur'' evolved independently or early wwhen they converged with the ancestor of dinosaurs.
Dumbshit profile picture. Anarchy is capitalism by the way
man 95 million years ago my 9500000000x great grandpa used to be the underdog and got ate by t Rex.Well today I'm eating a chicken aka bully T Rex .Can't wait for one of my 95kx grand children to be eaten up by Mr rat,the underdog of our times.
+Chris Martinez well the dinos would have eaten him anyway.And Yea I meant all carnivores dinos when I said t Rex.I only pointed t Rex since it is popular
+Not Telling Yes, we know it. Mammals descend from small reptiles who became small mammals, that after became placentary mammals.
Does that mean we were eating Dino nuggets from McDonald’s???
Yep!
its times like this when its easy to see that DNews is only ever about 50% accurate
I have a parrot and I named him Dinosaur. No joke.
Ha ha we eat dinosaurs now.
well some not all birds are tasty like chicken, some are nasty to eat and some a even poisoness :)
+rexon31 only one is poisonous and only from its food if raised in captivity it would be fine to eat.
very true but the reason penguins still survive today is because they taste terrible unlike other sea birds that can be quite tasty or they would of went extinct a long time ago . only specialist hunters like sea lions and whale eat them from time to time.
rexon31 Chicken isn't bad, I find it more tasty than... Say beef or Pig
they ate us now we them, justice
For sake of debate;
Many say evolution proves that humans were not created by god (and thus indirectly proving that he does not exist). But in bible there is part that i recently heard about, i don´t remember word to word but it was like this "1 000 years is a mere moment to god"
So time it takes humans to evolve to what we are now, could easily be time what god considers to be one day.
And science vs religion debate is in some ways idiotic, for example becouse science is about proving things, while religion is about believing things.
Personally i think luck, nature, coincidence etc are all what we call "god", i have no doubt that if there is such thing as god, it/he is not some old man sitting at top of a cloud and throwing lightnings to humans.
Or could we all just agree that religion is human made and its at best a bad fairytale written by people living in desserts 2 Milena ago...
Ishzarks Yeh, but that would mean 33% of TH-cam`s comments would be lost... Another 33% are boobs in thumbnail, and remaining 33% Hitler.
It's only a theory that we came through evolution. There is still a missing link between us and the Neanderthal. It's even more strange that different species of humanoids lived on earth at the same time and were most likely unable to reproduce with each other; the homo-sapiens (us) and the Neanderthals. There is another scientific theory that fills up the gap in between our evolution process and it is the ancient aliens theory, however that one is very controversial.
Gale nighting will people ever stop with "its only a theory" bullshit? its fucking proven, AND IT IS A THEORY. THEY CO-EXIST.
Nitay A. There is not much evidence to support that humans evolved the same way as every other species on this planet. Much less evidence because of THE MISSING LINK. I'm sorry but you took my comment the wrong way. I was trying to say that it's very hard to prove the evolution process of humans. There is much more evidence to support the evolution of every other species of the planet with Charles Darwin's theory of evolution, but humans are the pain in the ass. As I said, its only a theory that WE... WE came through evolution, There is wayyyyyy more evidence support Neanderthals evolving through the theory of evolution, but the homo sapien, not even close to as much evidence... and that's where the scientific ancient aliens theory comes in to fill the gap. But, that is only a theory as well, WITH PLENTY OF EVIDENCE... Because I already know that scientific theories involve the use of evidence to support a claim.
Whenever a startled robin flys away from me, I scoff and say, "Not so tough now, are you, Mr. Dinosaur!"
My mind was blown when I discovered the bee hummingbird is the smallest known dinosaur
Seems legit til you get woke and realize birds aren't real.
Birds descended from dinosaurs, but they aren't dinosaurs. That would be like saying that we're rodents, because that's the type of organism that our line descended from that was contemporary to the dinosaurs. Perhaps that's nitpicky, but cavalier imprecision like that is a huge reason why alot of the general public doesn't understand and thus outright rejects evolution by natural selection.
Incorrect, birds are in a sense avian dinosaurs as dinosaurs are non avian birds, granted that is a very general description, but birds and dinosaurs have so many things in common that they have to be the same thing. A mouse is not a human because we have little to no similarities, unlike dinos and birds.
Well a shift in the way scientists classify animals means they actually do literally consider birds part of the dinosaur clade.
You talk about "the general public" not understanding. You're right. These are edutainment videos. Facts aren't really important as viewing figues.
+Greenlion781 No, that's not how cladistics works.
Birds evolved from theropod dinosaurs. Ergo, they're a kind of highly derived theropod dinosaur but they never stopped being dinosaurs.
The mammals that were alive during the Mesozoic were not rodents, and FYI Mammalia is a crown group while Dinosauria is a class so you can't compare the two the way you just did in your comment.
We humans are primates, and we evolved from primates that were around during the middle Cenozoic. I.E We evolved from australopithecines and basal hominids, and since humans, australopithecines, and basal hominids are all primates, then remain apes even when we evolve from them.
When scientists say "Birds evolved from dinosaurs" they mean that birds are a kind of derived dinosaur that evolved from more basal, non-avian dinosaurs. They don't mean that by evolving, birds became a completely separate class of organisms from dinosaurs. They mean that birds are dinosaurs that evolved from a more primitive line of dinosaurs during the Mesozoic.
Luigi Gaskell You could begin your comments by naming the person you're responding to. I am sure your comment is not a response to me but it just helps to clarify.
Cool Video
I have pet dinosaur staring at and crowing at me as I watch this video.
Pffff LOL! HUH! Birds are as Much Dinosaur as Humans Being Apes! NICE TRY!
So.... you are agreeing then.
Why do you think people would fake that kind of stuff honestly? I get that you don't like being called an ape but it's okay you're still unique and special and a really nice ape at that, but seriously when you say "nice try", what do you think "they" are really trying to do?
Shnoppy it was....
So many religius people. Can't belive they still belive in creation when sience constantly are debunking them.
soo true
I keep hearing that science has debunked religion: how, specifically? Sources?
I mean, you do realize that by the very nature of religion, it is neither provable nor disprovable as a whole, right?
Nuada the silver hand thats why its debunked
because we cant test if its true or not
for exemple how do we know if we are not created in this second with all of our memories and stuff
we cant because it cant be tested
Nuada the silver hand in so much that we know the process by which organisms evolve, and math, and physics, and all other realms of science, directly contradict many principles of many religions. Sure, its possible that they AREN’t mutually exclusive, but it would still mean a vast majority of a certain faith is incorrect. Humans could have descended from two people, but based off of what we now know about genetics, statistics, and fossils, its likely that’s not how it happened.
What I want to know is where bees came from, and at which point did they evolve from whatever, to assist in the pollination process of flowering plant life.
Stinging insects have been on earth for a long time
Also, questions. Saw a story of Dino footprints in a creek bed made millions of years ago. #1 How are muddy footprints preserved and #2 How can a creek (or any water features like a creek) remain after millions of years?
Short answer: sediments depositing in place.
