Excellent idea. It showed up not long ago geologically and changed the face of the earth. So much of today's life has evolved to take advantage of grass. It's also one of the staple crops that allowed agriculture to begin. 32 of the 56 species of nutritionally viable grasses evolved in Europe, that really effected history.
@Ambrose Burnside Pretty sure most if not all lawn grasses are European Middle Eastern or African in origin as Lawns are formed from spreading grasses and Europeans believed North American grasses were inferior and cattle didn't take well to them. Most names come from where the cultivar was first developed such as Bermuda Grass and Kentucky Blue Grass which are based off crosses of European and Middle Eastern grasses. Lawns also only date back to the medieval period so there isn't much of a history as it is one of those newer than it seems that only really became possible with continuous influence of servants and later toxic and environmentally destructive chemicals. Lawns are native to nowhere and are purely a product of human selection by rich nobles that wanted to show superiority over nature and nowadays are the worlds most cultivated crop despite providing no ecological or productive value whatsoever. Wild grasslands are instead a diverse mixing of many species of herbaceous plants most of which we have labeled as "weeds" because they are of course far better suited to the environment than our nonnative lawns that are helpless without constant human intervention.
I have no idea how they could cover this topic on a vulgarization channel. It's really not as cool as you all seem to think it is, given that we obviously have very few examples of fossilized blood and other internal organs (except brains probably). It's already hard to have strong opinions about things when we have a lot of skeletons to begin with, what makes you think that the evolution of blood would be interesting? It would mostly be speculative stuff based on how certain proteins look and what does arthropod blood look like. We do have some examples of fossilized blood (including from dinosaurs) but there's a reason why it's not a very popular topic: all there's to say about them is only interesting for specialists. Anyway, this is a better topic for a biology channel, not a paleontology one.
Please do one on the evolution of hyenas. It would complement the canid evolution videos you've already done quite nicely, by showing how convergent evolution works.
I'm still eager to watch a video on the history of the placenta, as well as more on land animals that thrived in the Permian, right before the first dinosaurs. Learning about Brachiopod evolution would be cool too. :)
@@2008-wii-remote I think it's more that we have much lower metabolic rates, much better immune systems (because we are more social), much broader diets, and being endurance predators is many time less dangerous than ambush hunting like they did.
Hey can you guys do "The Bone Wars". It wasnt exactly a story about natural history, but it was one of the biggest milestone of our natural history's history. So many fossils were discovered, but many were destroyed too.
I have an idea for your next video. When did plants evolve to bear fruit? Is it possible these early apes only ate leaves because fruit didn't exist yet? I have no knowledge on this and would love to find out find out from you guys.
I'm no paleontologist, but my guess is fruit evolved from a covering of thick fleshy leaves grown together at the edges, originally to protect the seeds from animal bites. At first they would protect seeds by being thick and hard, and then by poison. Later, some fruits would lose the poison and evolve sweetness to reward some animals for spreading the seeds, in cases where seeds could survive the animal's digestion. Notice how some fruits are safe for some animals and poison for others, which suggests animals and their favorite fruits evolved together.
Photo- Scribble fruit fossils exist from the late cretaceous at the very least; considering that plus the diversity of fruits today, there were definitely plenty then. at least in the tropics/not europe, that is
Crocodylomorphs! They were super diverse and widespread all throughout the Mesozoic and Cenozoic. They filled a variety of niches as grazers, fast running predators, and possibly even filter feeders. And fully terrestrial and marine species died out only very recently, so early humans likely had to deal with them as a natural hazard of life! I would not be surprised if a lot of myths about dragons and sea monsters are based on these very real creatures who we shared the world with.
@@ilovecheez7769 they are one of the three big groups of archosaurs, which also included the dinosaurs and pterosaurs. They survived The Great Dying, diversified alongside the other archosaurs, and some survived the Cretaceous extinction alongside the flying dinosaurs. They diversified again into many terrestrial and aquatic forms, including marine species. Today we have just a tiny fraction of what was around just 10,009 years ago.
"What do you want to learn about?" I want to date a paleontologist. Wait... no, that's not right. I want to learn about dating methodologies for various paleontological discoveries. How are we able to tell that this ape lived 16 mya, and the other ape was 12 mya? Is there always a "plus or minus 500,000 years" included?

Can you make one on fungi? From the beginning of earth to the Vikings using amanita muscaria before fighting, or why do magic mushrooms evolved to be psychedelic ?
Its interesting how diverse the whole group is there is also evidence particularly genetic that insects actually are a suborder within Crustacea having "recently" split off from fairy shrimp somewhere between the Ordovician to early Devonian time frame probably the Silurian around 400 million years ago Arthropods go back ways back "suddenly appearing in the fossil record as a diverse assemblage indicating they go back even further in time.
First appeared as a core, a hard core, then evolved into crust, crust core, or crust punk, sharing some convergent evolution with grind core, which unlike the Earth or Death metal is not metal at its core, but a hard core of punk actually.
Thanks a lot for this video! Very interesting to see apes apart from humans in Europe! The transition from sub-tropical forest to deciduous forest mentioned in the video made we want to ask this question: Is it possible that you could do a video on the evolution of trees?
Which type of trees? Plants seem to have independently converged towards what we recognize as trees quite a few times from the Giant Horsetails, and Scale Trees, progymnosperms(ancestors of gymnosperms) of the Paleozoic to the later "seed ferns" from which Angiosperms would emerge from to convergent achieve treelike structures multiple times even among the woody plants we think of as hardwood, if that wasn't enough even Ferns got in on the action in the southern hemisphere as has giant Bamboo in eastern Asia. So really there is no one group of trees given the plants we call trees emerged from very different branches of the Plant kingdom/family. It is just a really really popular form for convergent evolution....
@@Dragrath1 Is this a question or a replacement for a video that mightn't come? xD Jk, thanks for the info that I wasn't aware of. I really just think that plants are very underrated in popular paleontology and want to maybe learn a bit about how they came to be the way they are today, and I thought perhaps I should ask broadly if they would cover trees before specifically ditto.
Love this channel! I'd like to see an episode on organisms that inhabit the deep earth and permafrost and other places that were once considered lifeless. When did they evolve? What do they tell us about the evolution of primitive life? And since they live so long, do they act as a repository of ancient genes that get traded with more active organisms? Thanks!
Blake videos are awesome. I’d love to see a video on the history of canines, where they got their start, how they radiates across the globe, and how all the extant species are related.
Suggested topic: I used to think that New Zealand was once attached to Australia. But having visited both New Zealand and the south west coast of South America, I noticed that the plants and climate of these two places were far more similar. Thoughts?
Can you make a video about the origin of land plants? There seems to be no universally agreed date on when they first showed up, it would be interesting to know about the different theories and evidences we have on when and how they evolved.
Can I suggest doing some shows specific to Epocs, the Miocene fascinates me, but I am sure would love some shows on them all so we get an idea how the world looked and what it contained. Thanks
I think carnivorous plants started out as plants that had hairy leaves that were just trying to keep insects from eating the leaves. Later the hairs evolved to produce a sticky drop of sap to gum up the insects' jaws, then get them permanently stuck if they didn't go away. Then as the insect bodies decayed, the decomposition products would be absorbed by the leaf, fertilizing the plant as a side benefit. This encouraged the evolution of the sticky secretions having digestive enzymes to break down the insect body faster. At this point we have the Sundew. Later refinements caused the evolution of trigger hairs that cause the cells on the opposite side of the leaf to divide all at once, causing the sticky side to curl in on the insect. As the trapping leaf mechanism became more efficient, it became unnecessary for the inside of the leaf to have sticky hairs, so those disappeared, leaving just the trigger hairs in the middle and the interlocking "trap" hairs along the edge of the leaf. At this point the Sundew evolved into the Venus Flytrap. And then there are the Pitcher Plants, a completely separate development evolving from plants with curved waxy leaves trapping rainwater that insects just happened to slip and fall in. Originally the pitcher mechanism was just to funnel rainwater toward the roots. Pitchers that developed sweet-smelling leaves trapped more insects and got better fertilization from the rotting bodies. Later generations of the plant secreted their own water into the pitcher so they didn't have to rely on rain water to fill them up. Later, like the Sundews, they evolved digestive enzymes to break down the insects faster than decomposition.
i'm fascinated in all those surreal and alien-seeming soft-bodied sea creatures. i'd love to see something that covered the evolutionary trajectory from the jellyworld of the proterozoic, when almost everything was soft-bodied, to the spectra of soft-bodied sea creatures we have now; jellyfish, octopus, squid, and creatures like the cuttlefsih that are kind of inbetweeners between softbodied and crustacean. so a long way around of saying +1. i would def like to se this one too.

@Mac Mcskullface agreed re scarcity, but as this site (random example) shows www.fossilmuseum.net/Paleobiology/Precambrian-Fossils.htm proterozoic eon (precambrian) 'fossils' (be they physical, indexes or chemical signatures) are increasingly being identified as our understanding (of what exactly we are supposed to be looking for and where) and tech (to be able to detect ever subtler traces) advance. another area i'm fascinated by are those lost branches of life that existed simultaneously with LUCA for a while, a long while, until LUCA eventually out-evolved and superceded them. many wiped out by the great oxygenation event (anoxic life forms). jurassic gets the mainstream ateention and the clicks re web media, but the proterozoic is what gets me buzzing. along with everything else. the history of earth is a pretty big subject. hence my abiding affection for these eons vids.

Hi PBS Eons I found this episode about Ape's from Europe fascinating and interesting. Hank as usual did a great job of covering this topic. I was curious 🤔 if there were any Ape's from Europe.
Question: I want to know how differences in chromosome counts evolve? Like how humans have 23 pairs of chromosomes and chimps 22. How does this happen as it seems having a mismatched amount of chromosomes between gametes would cause reproductive problems. I have asked quite a few people about this and no one has a solid answer. Thanks
During meosis (the cellular division which creates gametes), there can be anomalies, and a gamete might end up with 2 copies of one chromosome, or none at all. These anomalies are pretty common (around 1 in 1000 birth have trisomy 21, which arise from one of the gametes having a chromosomal anomaly), and if, by random chance, 2 gametes which each have the same anomaly give rise to an egg, this egg will have a new pair of chromosomes (it would be a quadrisomy). Most of these are fatal though.
I just want to say that this guy has amazing versatility with ridiculously complex vocabulary. I can't believe the words just role of his tongue with such alacrity.
I'd like to see an episode on the evolution of grass and how the world looked like before it existed. It's hard to imagine: a world without grass.

another area i'm fascinated by are those lost branches of life that existed simultaneously with LUCA for a while, a long while, until LUCA eventually out-evolved and superceded them. many wiped out by the great oxygenation event (anoxic life forms).
jurassic gets the mainstream ateention and the clicks re web media, but the proterozoic is what gets me buzzing. along with everything else. the history of earth is a pretty big subject. hence my abiding affection for these eons vids.
They don't fossilise. Sad.
Your videos are very well done!!! I can't think of anything I would change off the top of my head. They're short so you don't get bored there upbeat so you don't get bored. And they are chock-full of information. I'll give you a 10 out of 10. I always am grateful for people to do things like this to better educate us. I don't think these type of videos get enough praise.
This channel is addictive!
I like it ❤
I've been following this channel for a few months now and it really is absolutely outstanding.
How do i become a paleontologist? (Classes and stuff like that)
University
@@bryndel well da
@@gamermthegreat8229 Look up colleges/universities with good or well renowned paleo programs and start applying.
Study, study, study. I hope you like reading really dry science books.
@@nw932 im in high school and in Indiana there's not really schools for paleontology ariund here.
Could you guys do an episode on the rise of grasses? It's pretty important! Particularly as they are one of our most import sources of food.
Do when dogs and cats were one
There was an old Tv series named 'The Velvet Claw' where they show it in cartoon-animation. And that show had a super-cool opening score!!
@Internet User it was a cog. or a dat. a cag. or a dot
So good boys expect they Actually have hunting skills
You mean Miacids?
That was the late 90s. CATDOG!
(Plays intro music)
2:05 - wifi molars.
Pretty advanced stuff.
Yep
I just LOVE every single Eons episode! I just wish they were 2 hours long at least!
This channel is a hidden gem!
Evolutionary history of bears.
Well done
Moth light media did a video
I would love to see your take on Doggerland. There isn’t enough about it on TH-cam and I find it fascinating
Love your channel, keep it up!
Those apes still inhabit Italy , we Italians call them "calabresi"
Do a video about land crocodiles pls
Can you do a video on the extinction of the Ice age creatures
Your comment warms my heart✋✋✋👍👍👍👍💜💜💜💜💚💚💚💚💚💘💘
An episode on felines would be awesome.
Done
Hi PBS Eons I found this episode about Ape's from Europe fascinating and interesting. Hank as usual did a great job of covering this topic. I was curious 🤔 if there were any Ape's from Europe.

I know you already did an episode on dimetrodon but I'd love to see an episode on his sailbacked relatives like Secodontosaurus
Do a video on the denisovans please
Yes thank you also thank you for referencing ouranopethicus and graecopethicus
Question:
I want to know how differences in chromosome counts evolve? Like how humans have 23 pairs of chromosomes and chimps 22. How does this happen as it seems having a mismatched amount of chromosomes between gametes would cause reproductive problems. I have asked quite a few people about this and no one has a solid answer. Thanks
During meosis (the cellular division which creates gametes), there can be anomalies, and a gamete might end up with 2 copies of one chromosome, or none at all. These anomalies are pretty common (around 1 in 1000 birth have trisomy 21, which arise from one of the gametes having a chromosomal anomaly), and if, by random chance, 2 gametes which each have the same anomaly give rise to an egg, this egg will have a new pair of chromosomes (it would be a quadrisomy).
Most of these are fatal though.
Cheers guys, these are perfect for my learning style. Repeated bursts that make me think.
This music makes me feel like I'm watching a 1950's education video. "Isn't that right, billy?" Not complaining, more just... noticing
They are doing it again....
Do one about how prehistoric Antarctica and the north pole were.
Wow, very interesting. As usual! 😁😁😁😁 I absolutely love EONS channel, so fascinating
Do more videos on hominids
I'm not kidding you, I just finished munching on 2 Oreo biscuits LITERALLY before he mentioned about oreopithecus.
Talking so fast......but what I caught was fascinating.
I just want to say that this guy has amazing versatility with ridiculously complex vocabulary. I can't believe the words just role of his tongue with such alacrity.
Mastodon! The most metal of pachyderms.
Excellent as usual. Thanks for hard work.
How did the Himalajas impact the climate of Europe? Was it because of the shift of the ITC?
Excellent! Really enjoyable documentary 😊
id love a vid on ichthyosaurs, keep up the excellent content though :)
Steve, whoever you, wherever you are, your everyone's favorite!
