I'm really glad you guys are doing these channels, thank you. Such high-quality work. It's very hard to find content that meets the standard you all have set.
what is a "monke"? Humans diverged from apes-specifically, the chimpanzee lineage-at some point between about 9.3 million and 6.5 million years ago, towards the end of the Miocene epoch
I love that you're covering the topic of the rise of mammals. Most corporate producers would write off the idea of making a documentary series about the path from early proto-primates to humans "too boring."
No, it's complete nonsense. We began, at most, 100k years ago. The "rise of the mammals" ended 10s of millions of years ago. Mammals have been the king of the Earth for 10s of millions of years.
@mikael557 you just thanked God for the internet helping to convince people God doesn't exist. You're a perfect example of the complete lack of self awareness in people these days.
This is one of the coolest videos I’ve seen on YT this is beyond class mate! Thanks for the great breakdown and explanation that’s ‘concise’ lol and direct! There’s a lot to go over and I LOVE the attention to detail!
The most significant evolutionary event for humanity was when humans learned to direct evolution to their own advantage. It is this knowledge that makes civilization possible.
Unfortunately their latest attempts at directed human evolution may well be humanity’s downfall what sort of lunatics would inject plasmids mRNA and some chemicals and zoonotic diseases from mammalian cells and think that would make safe vaccines against disease? They r probably now caused more diseases than any other century the stupidity of some scientists and greed of some business people and politicians is beyond comprehension!
@@nathanialthomas6889 Does that mean you think humans did not use selection to develop the domesticated plants and animals that we depend on for food even today? I guess we could argue what is more important, tools or agriculture, but it would be an irrelevant and stupid argument.
@@andywomack3414 We got along just fine for 98% of our modern human existence without agriculture or civilization. Fire and tools however, were, and are, vital.
I really like your writing style. All the little nuggets of wisdom (history of science 9:40+, chemistry, geology etc) paint a far more rounded picture without it being overwhelming/ too drawn out. Neat.
I appreciate the comment at about 35 min stating free hands could hold tools and carry children. As a mother who has packed around children trying to do routine tasks with one arm (as the other arm is holding an infant) I long ago concluded the first tools of being bipedal were slings to hold an infant. Bipedal infant toes couldn't help attach themselves to the mother so a sling would be needed. Perhaps twisted plant material which, of course, would not be kept in the fossil record like evidence of stone tools. This would lead one to think the stone tools came first. But if the female population is handicapped by only having one 'free' arm, that just doesn't seem possible. The infant sling had to come at the cusp of bipedalism just for the survival of the species.
Really good points. Countries like India and China show how much industrial work can be achieved by women carrying young in fabric slings. As you correctly point out, only a very rare environment would allow the preservation of such material. Permafrost or peat bogs. I'm hopeful many new discoveries will be revealed as the ice on the poles melts.
there is a sadder counterpoint to this, and that is that monkey babies can hold onto their mothers but human babies cannot. We come from the lines of women who could carry their young and not those who kept dropping them.
4:34 For a split second there, I thought something had gone horribly wrong on that boat, and then I realised that those are just the parts of the deck where the finishing had weathered off. 😅
10:10 infrared moves more slowly thru the atmosphere? Ouch, no, it actually travels very slightly faster than visible light. But that has nothing to do with how it causes the atmosphere to retain heat- that's simply due to the fact that it is absorbed by water vapor, CO2, methane, and some other gasses in the atmosphere. So the earth is initially heated by the sun mainly via visible light, which is not absorbed by these gasses, but then when that light warms the surface, the surface starts to re-radiate that heat in the form of infrared, which is absorbed by these gasses in the atmosphere.
I believe the writers were saying IR light moves more slowly through the atmosphere than it does in a vacuum or in space...not comparing it's speed to visible light.
@@PowerScissor But that would also be true of visible light, and has no connection to heating. The previous sentence says IR wavelengths are so long we can't see them (implicit comparison to visible light), and then this sentence starts with "these wavelengths *also* move more slowly...", so to me it sounds like he's comparing to visible light. One interpretation that might make sense is if he's referring to the idea that IR photons would get absorbed in the atmosphere, but then some would later be re-emitted, essentially slowing them down.
Here in Phoenix, that heat wave is just is the relatively gentle start of summer before it get up to 45 °C - 50 °C with overnight lows in excess of 30 °C. I really hate living here.
@@mikieswart A meter is more than 3 feet, not less. So it would be more than 10k feet. Nevertheless, the drill is maybe 12-24 inches. From what I understand, it's all done 30 feet at time.
@ia8018 I have no quibble with the production values. But passing this off as fact based on "the science" is unseemly, and, quite frankly, a lie. If they'd started with 'We don't know for sure, but here's how it might have gone...' ... but they didn't. Instead we get some climate scary going and then it's storytime. It's entertainment, and that's all. Michael Crichton would be shaking his head.
@ia8018 : I am denying it is caused by man, or is significant in any way. It's called 'the weather'. The fact that climate alarmists, particularly the wealthy ones, seem still to be buying waterfront property suggests a lack of adequate skepticism on the part of others. Follow the money. Crichton was right.
Speaking as someone who has studied cultural anthropology and soil science, I found it fascinating. Your vid ties together a lot of loose ends. Really great info, writing and presentation!
How to tell if a place that is cold used to be warm. Step one: see that plant fossil? Step two: see an plants anywhere else on the frozen continent? Step three: if no, shit probably got warm
Ever since the Covid shutdowns, I took on getting up to speed on the earth's history, and life in general. Most recently, I've been especially interested in the rise of mammals to primates and their evolution towards homo sapiens and our predecessors. In the grand scheme of history, it's amazing how recent this all is. This was excellent and I look forward to more. You've got a new subscriber.
Just imagine 20 people in a room, each 100 years old. Their 20 lives stacked end-to-end would put you back to the time of Jesus (just 20 lives!). 200 in the room gets you back to the ice age. 2,000 in the room gets you back to the 1st Homosapien. 20,000 gets you back to the 1st walking ape. I think 660,000 lives, each 100 years old, stacked end-to-end gets you back to the dinosaurs.
Why do I get emotional watching every single one of your videos? 😅 I love learning everything from your creations & narrations, I dream of one day picking your brain 🧠
These are the best 2 channels I've ever seen on any platform, T.V. (when that was a thing) , or anywhere, whats the most mindboggling thing is how theres not a million plus subscribers to them, ahh ahh i dunno. Throws me for a loop.
He’s got 3 History of humankind History of the earth History of the universe They are some of the best. North02 is fantastic as well for the different kinds of humans we’ve been
"fragility of life"...are you kidding me? Life seems to be massively resilient. Species go extict, but that leaves room for others to fill new niches and to adapt and proliferate. Life finds a way.
in order to be resilient you have to have difficult conditions. hence life being fragile? what are you on about? something can be described as more than one word😂even if they aren’t synonymous.
20:00 Equatorial regions don't have summer! If you are the equator, the sun rises at the same time every day, sets at the same time every day and is high in the sky at noon every day. They tend to have what they call wet and dry seasons, but not the seasons we at the higher latitudes have. The seasons are caused by being in high latitudes.
"the sun rises at the same time every day, sets at the same time every day" - This is incorrect. The tilt of the earth still affect the length of the day at the equator.
@@michaelwilliams2430 Not at the equator. I just double checked (on the off chance I got something so basic wrong) and every day of the year is the same length at 0 latitude. 12 hours of sunlight, 12 hours of night.
at the equator, the sun will be directly overhead at noon on the equinox but will be to the north or the south during the solstices. you'd get sun from the north during the northern hemisphere summer, and from the south in the southern hemisphere summer
Antarctica, South America, and Australia were also once connected creating warm waters. Once they broke up it created the Antarctic current and cooled the planet.
I like trying to guess where this guys from. I’m gonna guess English is not his natural tongue. I’m gonna say he’s rearry probabry from Japan. I’m so fried watching this shit and I can’t get enough of it. Thanks, you beautifully articulate International man of mystery!
34:00 Latest research apparently shows that knuckle-walking is a later chimp/gorilla/ape mutation. Ours and apes' ancestors were bipedal upright walkers.... I love science!
@@ConontheBinarian Bipedal due to balance walking on tree limbs -- yes, indeed! And it make lot's of sense. That stupid "walking upright because there were no trees left" always felt and looked SOOOOOO wrong to me. I am over 60, FYI.
@@ConontheBinarian yes, indeed! thank you! FYI, research shows, the ability to upright walking has nothing to do with thinning trees nor with unavailability of such. No "solidification of adaptation" was needed. Bipedality was shared by all humanoids before the great apes' separation from our evolutionary tree....chimps, bonobo, gorillas, gibbons, macaques, spider monkeys, capuchins, and others are all frequent bipedal walkers. Scientists discovered Ardipithecus ramidus, a human-like hominid descended from the common ancestor of chimpanzees and humans. Ar. ramidus engaged in upright walking, but not knuckle-walking. This leads to the conclusion that chimpanzees evolved knuckle-walking after they split from humans six million years ago, and humans evolved upright walking without knuckle-walking. Yes, you are more correct than you think - no "walking" through ice sheets ever happened, as it is physically impossible. Humans used dugout tree kayaks and of course fished and hence traveled near the shores - check out the early 1900 images of South American Patagonia nomads who lived and moved around in such canoes.

What is never entered into the equation of past climate conditions is plate movement. Things we see in the fossil record doesnt mean that is the location geologically speaking then as it is now.
40 years old. I am a huge fan of EHOtU as well as HOtE. So glad to see another channel. If they would have had something like this when I was in middle/high school, I would have not been so bored in class.
I beg to differ . . . I think that we did not so much adapt or evolve to survive in various environments - instead, we used our brains to create tools that _allowed_ us to survive in environments we did _not_ adapt to. From clothing to hunting to housing to heating to food production . . . _these_ are the things that allow us to survive in environments that would otherwise kill us outright.
Evolution played it's part. You don't find any tall thin dark skinned people that naturally evolved in far northern climates. Dark skin combined with lack of sunlight leads to major Vitamin D deficit. Skinny tall frames lose heat more rapidly in cold weather.
I think the name of this video should have been more like "climate change through the ages" or something, i feel i still dont really know how earth was like when humanity began.
Thank you guys for another fantastic video. The idea of the Arctic Ocean as a massive freshwater sea blooming with plant life sounds magical to me, sort of like the old Greek myth of Hyperborea. God be with you out there everybody, and Merry Christmas! ✝️ :)
I find your voice very soothing. Are there plans for these videos (as a form of podcast) to apear on spotify? Like a similar channel on youtube does...(mayne you know who i am talking about ;) )
that opening is basically what was predicted in the 90s... And compared to today's politicians? Those of the 90's look like they were taking sharp action. Yet at the time it looked like it does now. Suits beholden to fossil fuel and old men who didn't care about the future as they'd be too deadto suffer through it.
I swear. I don't know English so good but I can say. This is a good a** cuality content. Meybe I am high, maybe I am drunk, maybe this video pop up in my recommendation. But. Is bon a drunk answer, I'm 23. You're good my brotha, salute from Raval Barcelona. Dominican 💕 love
it is misleading to say uptick in calories available for our brains, but revealing to say hands are for tools and holding children. More food means more children. better tools means more children. Bigger brains means better children. More better children means higher adaptation rate. Higher adaptation rate means less adaptation needed. Less adaptation means single species.
How. And why aren’t we now if we can? And if there is a reason we cannot, why aren’t we addressing that issue? That’s like having a bleeding wound and saying ‘I could stop the bleeding if I want’ and then not doing anything until you die.
