Human beings have brains that are more or less the same as they have been for about 250,000 years. That's the late Pleistocene period, in which Homo sapiens were well, back then living in small bands of 30 to 50 kin-basedindividuals. They knew each other in real life, they saw each other every single day. They knew they were related
I think that it's very comforting to believe that certain phenomena are natural or biological or are hardwired in, like the Pleistocene era. And we all love-- we don't, I don't, I love carbohydrates-- but many people love Paleo diets, or this idea that something was natural
According to the report, above the skeleton was a thick layer of slate rock that was unbroken. things as early Pleistocene , early middle Pleistocene , and things of that sort.
This has become very stable societies. Quite the opposite of those Upper Paleolithic Pleistocene societies. At Catalhoyuk, this is where we're excavating in the south part of the site in a small area.
bits and bytes; cogno, neurons. And they even created a Pleistocene park.
group of hunter-gatherers in Tanzania called the Hadza. The Hadza have been hunting and gathering continuously as a culture since the Pleistocene . They don't live in, you know, the same, exact same circumstances as ancient humans, but they
Something else is kind of taking over in a way. And we have to go all the way back to the Pleistocene to explain this.
This is a musk ox. Musk ox is a species that's represented now-- in the Pleistocene , there were four species of musk ox. There's only one left.
Cool. So those kind of qualities-- and there are a whole lot more-- that's what I've been trying to develop consciously since I was 19. And that was way back somewhere in the Pleistocene Era as far as I can remember. So how did I get into this?
We send in there a bit of synthesized mammoth DNA. So there's a place up in Northeastern Siberia called Pleistocene Park.
According to the report, above the skeleton was a thick layer of slate rock that was unbroken. So if it was from the middle or the early Pleistocene , that would be anomalous for them.
So the Church of England was created, the dissolution of the monastery was about to happen. The quarry was gravel, Pleistocene , 920,000 years old.
You can count on getting food from someone else. There's decadal scale variation that we know is going on in the Pleistocene in Africa, and if you had great information, you could say,
bits and bytes; cogno, neurons. Not Jurassic Park, but a Pleistocene park in northern Siberia.
So what I've got here is-- it's temperature proxy data, so this is inferred temperature by a million years before present, so we're going from more ancient to more recent. Humans are a product of what's called the Pleistocene , which is a geological epoch that spans from about 1.8 million years ago to about 10,000 years ago, and the two things that should be really obvious from this plot are that one,
According to the report, above the skeleton was a thick layer of slate rock that was unbroken. So they would have said, that jawbone was found in an early Pleistocene layer, which
According to the report, above the skeleton was a thick layer of slate rock that was unbroken. They expected human beings like us to appear only in the very latest, very recent Pleistocene
According to the report, above the skeleton was a thick layer of slate rock that was unbroken. But if we're talking about the formations that are millions of years old-- say early Pleistocene formations,
and which is bad? It's helped my ancestors to survive on the African plains, in the Pleistocene and before.
I called the South African Heritage Resource Agency, because there's actually cell phone coverage at the site, to get permission to take it out. Every animal we find is the most complete that has ever been discovered in the history of Plio-Pleistocene paleontology on the continent of Africa.
And in 2008, shortly thereafter, myself, my colleagues, You'll see huge volcanic fields, and you'll see dry lake beds that were, in the Pleistocene , home
For example, we've learned that bison, horses, and mammoths all peaked in population size around 40,000 years ago, and then started to climb. And this is interesting, because two of the main hypotheses about what caused the megafauna mass extinction at the end of the Pleistocene , when we did lose mammoths and many other of these big species, were that they didn't like the peak of the last Ice Age--
We send in there a bit of synthesized mammoth DNA. And he's been doing some experiments, where he's keeping them out of some parts of Pleistocene Park and letting them graze on other parts of Pleistocene Park
But most people feel that climate isn't the sole factor. But maybe not even the main factor, because there are earlier warmer periods way back in the ice age in the Pleistocene , which did not lead to the same response.
there is the possibility, that as faithful as we've started out and as faithful as we intend to be, that changes will come into effect--what I call the "butterfly effect." Which I'm sure, being the audience you are, you all understand because you've read Ray Bradbury's "A Sound of Thunder." You step on a butterfly in the Pleistocene and it seems very minor, but suddenly you return to the future and all of human history has changed because of that butterfly. A small change can produce large changes later on. And that's a question on the show. I mean,
