Very nice summary and beautifully done! When I was doing geologic field work in Kenya’s Rift Valley I had the opportunity to visit a few of Louis Leaky’s excavations. Very rich in vertebrate mammalian fossils and, of course, the exceedingly rare hominid material. Also…I’ve just about plowed thru all of your videos…and I feel like I’ve gone through grad school all over again (but this time totally stress free and most enjoyable). So much new material. My brain feels greatly upgraded!! Many thanks for all your efforts.
Thank you so much! I am so glad to hear you have been enjoying my videos, it makes me so happy to know that not only current students but also former students find them informative and even enjoyable! :D Also, what an amazing opportunity to visit Leaky's excavations, I bet that was incredible!
Oh wow! How did I not know about this channel until today?!? This is exactly the topics I love learning about, and you’ve presented your knowledge so expertly. I’ve suddenly got a lot of previous videos to binge watch!
Oh yay! So glad you found my channel and like the topics I cover! I hope you enjoy the rest of the videos, and please let me know if there is a topic I am missing that you'd like me to make a future video on! ;D

I love the way you put your videos together. Have you had a chance to connect with Gutsick Gibbon? She is a PhD student, like you, does crazy good YT videos, and her specialty is Hominin evolution.
Oh my gosh yes! I love her! Just found her channel a couple weeks ago and commented how much I love and appreciate her work. Haven't heard back, but I can imagine she gets a lot more comments than I do so I am sure she just missed it. Maybe in the future I'll try reaching out again. She would be amazing to get to talk to and is in such a relatable stage in life to me right now.
It is absolutely remarkable how the constantly changing world has influenced the evolution of many species. And the evolution from ape to man and how humanity became one of the most successful, most resourceful, and most intelligent species on the planet is just mind blowing. Humans have come a long way since then and have looked back at the days when the world was 100% wild.
I know it is so remarkable the things we are able to do and think about… it makes my brain hurt sometimes when I think about how deeply we humans can think hahaha😅
@@GEOGIRL I know right, same here. I mean we went from apes that lived in the trees, to humans that literally changed the world. That’s surely a lot to think about. Some of us just never stop thinking, our minds just keep on running and we’re unable to turn it off... ow my brain!!! 😅

Hi Rachel! I love all your videos. And most recently for me (I started at the beginning and worked my way to the present--with lots of geochem & geobio diversions), your Cenozoic bio videos are spectacular. You are so organized and lecture so well! Thank you. Evolution so amazing, both on a cellular/molecular level or a macro level. e.g., whenever and wherever there is a vacancy on earth--land or sea, shallow or deep, forest or grassland--evolution puts a for rent sign out and after several million years, fills the vacancy. Fauna coming out of the ocean, fauna going back into the ocean, up in the trees, away from the trees...It goes on and on with or w/o us! Solid work!!! MikeE
@@GEOGIRL I couldn't agree more. It's more amazing than the Big bang, as far as I'm concerned. I'm off this week and my friends are asking me, what you do on your vacation 🏖️? I had a very simple answer, Geo Girl! 😘 Then they asked me about Barbie, Tom Cruise, or Oppenheimer? I said nope, Geo Girl first! You actually sent me all over the internet. First of all I started with your historical list but had to keep going back and forth to other lists to fill in holes. Then there's chat GPT, Wiki, and plain old Google searches. Looking up ratios and tectonics, and filling in various questions that would arise in my mind about the epochs. All in all it was a great week. Learned all sorts of new stuff. And the more I read on the internet about geology the more I realize, and didn't know, how high tech your field is. It's come a long long way. I love life sciences. I follow and am a paid member of two people on CZcams. You and a masters in biology guy from India who does cell biology videos, Shabir Hussain. I love cell bio. It gets me closest to where we came from. Whatever's going on in that cell happened first. Well, that's not entirely true. Your field happened first - tectonics. Which is my segue into a suggestion for you. A lecture on how you people figure out where the landmasses were 2 billion years ago 🌍🌎🌏. Rachel, I hope you have a nice weekend! MikeE
Great presentation. Thank you. I also read that Neanderthal Eyes were 20% Larger than Modern Humans, and much higher on the face. They may have had excellent night vision. We have a social brain, whereas Neanderthals appear to have a visual brain.
Oh interesting! I didn't know about their larger eyes, I wish we could see better at night haha. I would say maybe we will evolve that in the future, but we probably won't because their is no need for us to see well at night anymore I guess haha! I guess if we had to choose between social and visual I am glad we chose social :)
what really makes me curious about paleontology is of how little we have even really scratched the surface of earth to study our history and the history of life on earth. we pretend we have the big picture figured out and we know awful alot, but we have excavated so little the whole picture could just be plain wrong. especially considering the facts that a) due to the sea level rise after last ice age literally all the best grounds where civilizations could have started are deep under the oceans, and b) considering the life on earth as a whole - we have done literally zero excavations under the oceans, where vast majority of the life that has ever roamed on earth has sunk into.
Well the good news is marine sediment that got buried millions of years ago is constantly being exposed where we can observe and sample it and then learn about the creatures buried at that time. And we actually do excavate the sediment beneath the oceans in a way by drilling cores which we dilligently examine for micro and macrofossils as well as chemical composition and isotopic trends. However, I do agree with you that we have SO SO much to explore and even if we were to explore every inch of Earth, we would never understand the FULL picture because the fossil and rock records are incomplete. But at least we can get a partially full picture and make new discoveries every day ;D
There are no fossils "under the oceans", since ocean basins are consumed by subduction at tectonic plate boundaries and freshly produced centrally in each plate by up-welling mantle material. Check it out...think it through. I know you can do it!
This subject is a hobby of mine. I am an engineer/ programmer by profession. Your presentations are the BEST I have seen and I've seen much. Great job!!
15:15 - It would've been interesting, Rachel, if Homo Erectus had managed to reach and cross Berengia into North America. Imagine human evolution if some of that species had managed to reach the Americas and started to evolve independently of the Old World. Also imagine if some Homo Erectus had been able to cross the Lombok strait and settle in Australia.
It is worth noting there is a large school of anthropologists that think of the "the savannah hypothesis" as a secondary event. If I recall correctly, the benefit of being able to stand and bipedally forage certain vegetation and hunt on the forest floor fulfills a seperate niche to that of arboreal omnivores like our LCA with Chimpanzees/Bonobos, that likely had less of an ability to use their arms when travelling along the forest floor. That's not to say, that if this ability was gained in the arboreal setting, it wouldn't of then rapid specialised in the expanding savannahs. It almost certainly did exactly that!
@@GEOGIRL Keep in mind, my sources on this were anthropologist/evolutionary types on CZcams who are referencing the primary literature, so I'm like a poor tertiary source here lol
I love the diminishing forest theory and agree both for mobility refinement and intelligence enhancement. Between forested areas there would have been both danger and opportunity. Decisions like eat scavenged plant or animals where found, or to take with to the destination forest. Or remembering the right kind of rock is available on one pat to the next place. Those are all time and distance concepts and managing those factors well might have been both required and a new opportunity for quite a leap. Plus having the free hands that those decisions matter. Once superior marathoner was added to the suite, it was off to the races for the intelligence trajectory. That one change in climate precipitated all that.
I know it is so funny that both my videos with thumbnails like this (this one & the dino extinction event one) have blown up quite quickly haha! But I think it is done now, I can see the peak has gone down. But I am kind of relieved that it's gone down now because many of the random people it was reaching yesterday were not the nicest about human evolution... 😅
I heard the hypothesis that the formation of the mesoamerican isthmus closed off the atlantic ocean currents hence warming the climate, drying up the African savanna from trees forcing our ancestors down from the trees.
Could it be, that the animals without the proper teeth just evolved into something else instead of going extinct? Love your lectures which I often watch during workout 🤓🌺 and congrats for your PhD!
Nice cat.....I actually studying domesticated Animals Micro Evolution from feral beast to soft and pretty started from 1st Civilization in Middle East 😎
Wait seriously?! That is so cool! What an awesome field to study! What's the wildest thing you've learned in the course of your studies? (pun intended ;)
Nicely done video. Cut by 5 minutes. Nobody reads the text. Look at a channel called TLDR news for inspiration on presenting. As a geologist I love the topic, i could listen for hours. But normal folks like 15 mind usually for learning videos. Overall 👍
Grass and C4 plants evolved mainly because of the lack of CO2, which is a result of cooling and longterm sequestration of CO2. Deserts today are actualy CO2 deserts, more CO2 means less water need and vis versa (stomata). Mankind evolved by controling fire, cooking food and therefore needing less way energy to digest, alowing the brain to grow. We also learned to use animal fur and hide to deal with extreme temperatures (swetting).
Really fascinated by the archaeological evidence of spiritual belief in Neanderthals. The traits that make us human show a long, gradual history of progress.
I know! I thought that was so cool as well. And we are so lucky to even have a fossil record complete enough to show us this gradual history and the preservation of artifacts that allows us to understand cultural and religous behaviors :D
Recent genetic studies suggest that the Cro-Magnons had dark skin and blue eyes, rare in modern times, but clearly discordant with the usual representations.
Haha you will most likely see more of my kitty, and yes! great idea, I will work on an elephant & horse evolution video (but fair warning, it may be a while since I have videos scheduled out really far) ;) Thanks for the comment & suggestion!
“Many were increasingly of the opinion that they’d all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans.”-Douglas Adams
Speaking as an artist, the climate-autotroph impact on heterotroph adaptation you emphasize has an appealing theme-and-variation quality in which the heterotrophs are the variations on the climate autotroph theme. I've always believed that Darwin's love of explicating the organisms adaptation to the environment was, at bottom, the artists love of the part being a beautifully effective expression of the whole. Industrialization, in 200 years, has destroyed that relationship which characterized previous human adaptation to a greater extent and all of biological evolution. We believe the world belongs to us not we to the world is the Native American criticism. Do you have a video on the rise of my beloved angiosperms and their global heterotroph impact? Many, many thanks!
Yes, I love that artistic perspective! I do have a video in which I discuss angiosperm evolution and diversification among other things, but it isn't soley on angiosperms unfortunately, I'll link it here if you want to check it out (it's my video about Cretaceous life): czcams.com/video/RyebbB0_xhs/video.html Thanks so much for the sweet and informative comment! ;D
Australopiticus did use tools in 2010 they discovered bones cut open to use tools these fossils have been radio carbon dated to 3.4 million years ago in Ethiopia and the only likely creature to in that place and at that time was australopiticus afarensis the lucy species
Curious why gibbons, the only other bipeds among living apes, are always left out as candidates for human lineage? They also have a gracile build and small face. Homo floresensis is similar in size and proportions. And then there's Ardipithecus, taller and more similar to humans. Phylogenetic analysis nests Australopithecus with Pongo and Pan + Gorilla when gibbons are not excluded. Details online at pterosaurheresies.
I somehow never heard of this idea for why the Homo brains expanded. But, sure seems to me a beautiful idea(that of the mothers having to hold their babies for a year or more, instead of climbing trees.). The rest was a pretty good presentation of everything I've heard
If this is the basic reason, then we can say our intelligence was . . . almost pure chance. The environment changed many times for many species; but, this one time, the right species with the right . . . topology . . . interacted in just the right way in order to go down the path towards intelligence. The smallest reason led to intelligence!
@@GEOGIRL The accomplishments of life are amazing - indeed. The origin of life from non-life . . . going from the sea to land . . . and then flying! I don't suppose we have all of this figured out; but, we're getting tantalizingly close. I grew up in the 80s/90's with James Gleick's Chaos theory book. I still believe in the chaotic dynamics origins of life. It still seems remarkable that life can tap photosynthesis, and learn to fly!
re: whales... Mysticetes, evolving from hippos and desmostylians are convergent with odontocetes, evolving from pakicetids and tenrecs (which also echolocate). Details online at pterosaurheresies.
Inferences on brain size, relative proportion of brain lobes, etc are highly speculative. Neanderthals were not necessarily less intelligent than modern H. sapiens. Of course, there is a tendency for us (modern humans) to "grade" intelligence by the ability to do long division. One of our canine companions, if so inclined, could lead us to a fire hydrant, and challenge us to identify who had recently visited, reproductive status, etc, of which we would be woefully, hopelessly ignorant and dumb. A wonderful concept: Intelligence is optimized to the needs of the species.
What about when fire was tamed and which species tamed it? If it was homo habilis then homo should be a class, not just a genus, because using fire is as big a change in lifestyle as being active all the time with warm blood (mammals & dinosaurs) or laying eggs on land (reptiles). Or if it wasn't homo habilis maybe homo habilis should be demoted, ahd "homo" should start with the species that tamed fire.
I’m interested in ape to man 👨 crocodiles 🐊 ate our early ancestors and that we were prey to dinofelis and to eagles 🦅 back then found skull 💀 of the taung child 👦 killed by bird of prey
Would disagree with some of these hypothesis. A possibility is that eating meat gave sone of our tree dwindling ancestors an advantage. To get more meat they would spend greater and greater amounts of time out of the trees. This trigger bipedalism and expanding intelligence

The accomplishments of life are amazing - indeed. The origin of life from non-life . . . going from the sea to land . . . and then flying!
I don't suppose we have all of this figured out; but, we're getting tantalizingly close. I grew up in the 80s/90's with James Gleick's Chaos theory book. I still believe in the chaotic dynamics origins of life. It still seems remarkable that life can tap photosynthesis, and learn to fly!
By the way you are looking so beautiful
Thanks ;)
Hello geo girl. How are you ?
Doing good, how are you? :)
re: whales... Mysticetes, evolving from hippos and desmostylians are convergent with odontocetes, evolving from pakicetids and tenrecs (which also echolocate). Details online at pterosaurheresies.
The earth has always had winter, summer, fall and, winter. Your story about how evolution works is the most detailed fairy tale I have ever heard.
Inferences on brain size, relative proportion of brain lobes, etc are highly speculative. Neanderthals were not necessarily less intelligent than modern H. sapiens. Of course, there is a tendency for us (modern humans) to "grade" intelligence by the ability to do long division. One of our canine companions, if so inclined, could lead us to a fire hydrant, and challenge us to identify who had recently visited, reproductive status, etc, of which we would be woefully, hopelessly ignorant and dumb. A wonderful concept: Intelligence is optimized to the needs of the species.
What about when fire was tamed and which species tamed it? If it was homo habilis then homo should be a class, not just a genus, because using fire is as big a change in lifestyle as being active all the time with warm blood (mammals & dinosaurs) or laying eggs on land (reptiles). Or if it wasn't homo habilis maybe homo habilis should be demoted, ahd "homo" should start with the species that tamed fire.
Just the title made me think this was a video by the Babylon Bee.
I’m interested in ape to man 👨 crocodiles 🐊 ate our early ancestors and that we were prey to dinofelis and to eagles 🦅 back then found skull 💀 of the taung child 👦 killed by bird of prey
Great very direct 👍
Hate it when Americans do this things and talk to folks like idiots.
Kept me interested all the way thanks 🙏
Thanks so much! Glad it came off better than the Americans you are refering to haha! ;)
"Tree-ee area?"
Lol did I say that? Sounds like something I would say haha ;)
Adding meat to their diet enabled Great Apes and early Hominids to greatly increase the size of their brains.
Pyropythicus is human.
Would disagree with some of these hypothesis. A possibility is that eating meat gave sone of our tree dwindling ancestors an advantage. To get more meat they would spend greater and greater amounts of time out of the trees. This trigger bipedalism and expanding intelligence
Today I getting so late >.
Don’t worry! I still appreciate all your sweet comments :D
Since it is a German term, Neanderthal is pronounced Neandertal
Ahhh I had always wondered why some say it with a 't' sound, not it makes sense! Thanks :D
Sight of sitting is not possible
Neogene is the nice period to deposit super thick thermal coal.
"Climate change forced intelligence to evolve."
Really? Where?
It didn’t help me my IQ is 80 😐
Then why didnt it force intelligence to evolve in other creatures of the same climate 😂
Therefore the equitable climate we have had for the last 50,000 years is how we have evolved the remarkable stupidity of the last few decades.
BS
So gullible
