So my "friendly" neighborhood creationist is having difficulties understanding the process of terrestrial animals going back to the ocean. He yelled at me to show him a transitional form between a land mammal and a sea mammal (we talked about transitional species in general). I showed him a few transitional extinct whales but he wanted something alive today - a living animal halfway between land and water. So I showed him photos of seals, otters, hippos and beavers. He was not happy about it. 😂 Also when I asked him why do whales have lungs instead of gills (and how is that intelligently designed) he got angry and stopped talking to me.
I worked with someone like that, amazingly he was born with an defect in one hand (like the dude from scary movie 2) that had some mobility but was in general useless... so if that did not make him realize that there is no intelligent design, that genes, mutation, change are a thing and evolution is a thing, he laughed at the idea of unicellular life making it all the way to complex humans, i don't think a picture of penguins would do with this kind of people, they don't want to understand the world because they were taught that the only answer they need is "god did it". Also, he probably never played pokemon lol (i know pokemon is more like metamorphosis but i think it is a nice way of introducing children to the idea of creatures changing to become better adapted).
Yeah, I'd like to see this fleshed... chitined out. I already know that they're related closely enough to crustaceans that people with seafood allergies have to be careful around pill-bugs and such but would like a better understanding of the branching.
I remember flipping two overturned horsehoe crabs on the beach to get them up on their feet again So they are closer to spiders than they ever will to crustaceans
little scorpion fact that is shown here in all of its glory: you can determine the danger posed by a scorpions sting by looking at its claws: if they are large and strong and the tail is comparatively weakly build then its a wrestler and not very venomous. if the claws are more pincer like and the tail is comparatively musculous its a venom hunter and yes they are much more venomous.
Here in the Louisville Kentucky area we have several species of jumping spiders, all of which I greatly enjoy watching, they are the Raptors of the Spider world, screw all that spinning webs non-sense and waiting, they actively go out and hunt, I particularly like watching one sneak up on a fly and with an amazing last jump that wraps up their quarry.
My friend, you are making a big mistake. The quality of the production is really good but there are parts of the phylogenetic tree that are wrong. You cannot place trigonotarbids as the branch where spiders and scorpions came, it should be one of the branches parallel to them. The reason is that the ancestor of spiders and scorpions must have the generic (proto-chela). It must have appendages in the same way as the tools of the amblypygi. That way, It can diverge into being raptorial claws, chela or going back to normal tarsus and metatarsus. Because of that xiphosuras must also be another parallel branch, along side with pterygotus. Remember chela evolved from generic to specialized once. The ancestor should be a chelicerate with a similar generic raptorial claw like mixopterus (one of the eurypterid orders). That is impossible to defined because there is no DNA, so it has to be just branches without any specie inside the core of any branch. Sorry, I am not trying to be a smart ass, I really like your videos.
Arthropods, specifically Arachnids, are some of the most overhated animals. I get being afraid of them, but like actually hating them I don’t get. Love this video, wish more people gave arthropods nearly as much focus as vertebrates.
The fact horseshoe crabs survived both the great dying and KT mass extinction and have shared the sea with sea scorpions and mosasaurs and megalodons makes them really cool smh The fact they might not survive humans is just sad
No one can know what will exactly happen in the future, it can be build but not predicted. Also the survival of an animal depends on its capacity of adapting. Human extinction is just a *MERE SPECULATION* not an “established fact”.
Ha! That's a laugh. This is because the oldest fossils of Bats we have, already have wings, and look identical to modern bat with the exception of a long tail. We have no fossil of the origin an transitional species
At the time arthtropods moved to Land, oceans were full of predators and mostly competition for ecological niches. Land was "empty", with plants already, so it gives chances for some animals to explore new ways to survive. Also, during a long period they were amphibians, they can't leave the oceans in just one generation
fungi come from an aquatic ancestor, it's just that we know so precious little about current marine fungi that identifying their past is nearly impossible
There is a problem with the phylogenetic tree. You are placing as the first ancestor of the chelicerates as an artiopodan (trilobites and relatives). They are different branch. Both artiopodans and chelicerates came from the megacheirans, but they differ in that artiopodans have masticatory basipods all the way till the end of the last appendage. Chelicerates have masticatory structures on the head are follow the limbs without masticatory structures just like megacheirans. Megacheirans must be conected to chelicerates and the very first of them were Habelians and Mollisonians that have similar cephalic limbs just like ofacolus, the one you places as second after the artiopodan. Chelicera evolved directly from a megacheiran appendage and artiopodan antenules evolved directly from the megacheiran great appendage as well. However, on one side you have 20 appendage and claw like megacheirans like fortiforceps that are more "similar" to chelicerates, and on the other side, you have 15 appendage leanchoiilans with long great appendage ending in flagellum similar to trilobite's antennules. Please make an update using articles based on new Burgess shale discoveries and QingJang Biota.
14:58 - this spider is so big EDIT (6th July 2022): 15:00 - I'm sorry, but you overdid the size of this spider. This arthropod drawn by Satoshi Kawaaski looks more like a hybrid of the inaccurate Megaarachne reconstruction as a spider and a birdeater than a real birdeater. Well, it has too long legs, too big ,,cephalus'' and too big size. For a spider to be so large, there had to be an atmosphere on Earth like in Carboniferous, or the Earth would have to be larger than it really is.
Interesting. But I believe, the jump between Pterygotioidea and Arachnida is too big. I would love to see more mixed forms on their way to become Arachnida. Possible?
two of the most creepiest species of spiders is the wolf spider and the ogre-faced net casting spider, the wolf spider is well known for the close up photos of it's horrific looking face and unlike it's name sake they don't hunt in packs like actual wolves. ogre-faced net casting spiders are even more creepy due to them having really big eyes which are able to be repaired if damaged, it's an ambush predator which uses a slick made net to catch prey once it's prey is above it the spider strikes and tangles the victim in the net. did I mention that I don't like spiders? they creep me out.
I'm confused how spiders with silk even evolved? How does a mutation like silk and web making even happen? And how would spiders first learn to make webs?
We suppose it's quite recent but it's really hard to know anything about silk evolution because webs are too fragile to be fossilized and spide'rs fossil are really small and it's complicated to analyze organs. I've find nothing special about evolution of silk and webs. By the way, spiders don't really learn to make webs, it's instinctive, but as we don't know when and how it appears there's no significant answer sadly.. (in my own research of course, maybe I just haven't search enough!)
in the near future, your ideas of the "Sultan Spider" is that due to the huge amount of flooding in the Amazon they are mostly arboreal. sultan spiders get their name from the silk homes the make which resemble the turban of a sultan. a royal title in the middle east but not to be confused with either the Arabic position of caliph or Shah of Iranian history.
Plz do a part 3 and 4 for da speculative evolution series here are some examples of.future animals Neotyrannosaurus is the descendent to the Komodo dragon its niches r that of a T-rex and Adrewsarchus is 50 feet tall is in part 3 and the Leafy Dragon is the descendant to the Leafy sea dragon its niches are that of a Spinosaurus and a heron is is 17 feet tall is in part 4 thx plz add moar vertabrates to this series and add less invertebrates
11:50 Geralinura carbonaria lived in the Carboniferous 311.45 to 306.95 million years ago, not in the Cretaceous 99 million years ago. The map is accurate though. fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=272643
@11:40 -- not sure why I heard this as "Jew Spiders". I had to pause the video. I'm like "really??" There's a number of politically active people who wouldn't pause the video at all and be like "yup, mm hmm, Jews are spiders" and not give it a second thought.
![ILLSLICK X YOUNGOHM - We're The same [Official Video]](http://i.ytimg.com/vi/yUJNkobYR0E/mqdefault.jpg)
So the scorpions we have today are descended from prehistoric spiders, not from the sea scorpions themselves?
Wow, how interesting evolution is!
Yeah definitely is... especially when molecular genetics come into play
Or more correctly; they evolved from a common ancestor based on present day knowledge.
I guess those with afraid of insects or arthropods, should be real glad that sea scorpions don't exist anymore.
Or do they ?!? $?!?
No
Well fuck you veggieboy ultimate asshole
Lobsters?
@@locogiomotocroz4031 no, there's a difference
its so mad how a massive sea creature evolved into a tiny parasite youd think it would be the other way round

Show him Mosasaurs, Plesiosaurs, and Spinosaurus. And sea snakes

My pet spider enjoyed watching a video about her ancestry.
☺️
Cute
Sea spiders are so amazing
They look kinda boring though
I would have enjoyed this a lot more if a person presented the information instead of a computer
Agreed... This AI voice is super synthetic and grating
I appreciate the effort you guys put in your videos
The one thing I've noticed about Scorpion Species is as the claws on them get smaller and thinner, the Venom usually gets more potent.
Are you able to tell me why Argiope spiders group their legs together in pairs when resting?
Ah yes the well known spider active place *Scotland and the Midlands*
spore 2 is looking real good. Great video
Will you do centipedes and millipedes too because in the earlier video you included those in that group
Yeah, I'd like to see this fleshed... chitined out. I already know that they're related closely enough to crustaceans that people with seafood allergies have to be careful around pill-bugs and such but would like a better understanding of the branching.

Really good video, but I have one request.
Can you do one video on just chimaera and their ancestors ?
Done, my first video about prehistoric sharks!
I think that this video will be one of my favorite of the channel :D
Great video Anthony , thanks!
I’m so early that spiders haven’t evolved yet
Good joke bro,but you are only the third
Ey,dude stop ruining it

But aren’t we the same?
What do you mean about that,DkillrYt?XD!!!!!!!!!!
How does it feel meeting a Dog Sized Spider in the Dark? 🕷️😱

@@thejurassicman661 damn, would've loved to know more about that as well.
Where you found this maps?
I am pretty sure Santacaris from the Cambrian era was a member of the Chelicerata and could at least be closely related to Eurypterids.
My question "why and how did they move from oceans to land" remains unanswered.
At the time arthtropods moved to Land, oceans were full of predators and mostly competition for ecological niches. Land was "empty", with plants already, so it gives chances for some animals to explore new ways to survive. Also, during a long period they were amphibians, they can't leave the oceans in just one generation

everything came from water, is there any animal kindom that has terrestial origins ? Fungi ?
fungi come from an aquatic ancestor, it's just that we know so precious little about current marine fungi that identifying their past is nearly impossible
