Long after this wonderful event in the Earth's history, when the human species was spread over a good deal of Asia, Europe, and Africa, migration to the American continents began in attempts to find new feeding grounds and unoccupied areas for hunting and fishing.
Indeed, if our ancestors of millions of years ago hadn't learned how to care for one another and hunt in packs, they'd all have ended up being eaten by leopards.
We have enforced a Darwinian process on wolves, turning them into the shy and elusive animals they've become. They didn't have that fear of us 30,000 years ago. We didn't have gunpowder; we had rocks. Wolves would have seen us as lunch, and we were weak and slow and tasty.
But what really excited me was the idea that humans had a tremendous pre-history that went back millions of years. I wanted to go to Africa to find some of these creatures.
No conclusion is more fully established, than the important fact of the total absence of any vestiges of the human species throughout the entire series of geological formations.
We estimate that there are perhaps 20,000 prehistoric hunter-gatherers frozen up in those glaciers. Now, if they simply thaw and wander around, it's not a problem, but if they find a leader - a Captain Caveman, if you will - we'll be facing an even more serious problem.
That ere long, now that curiosity has been so much excited on this subject, some human remains will be detected in the older alluvium of European valleys, I confidently expect.
Animals' taste systems are specialized for the niche they occupy in the environment. That includes us. As hunters and foragers of the dry savannah, our earliest forebears evolved a taste for important but scarce nutrients: salt and high-energy fats and sugars. That, in a nutshell, explains the widespread popularity of junk food.
Humans have lived for much, much longer than the approximately 10,000 years of settled agricultural civilization.
Until about 30,000 years ago, there were at least five other species of humans on the planet. Homo Sapiens, our ancestors, lived mainly in East Africa, and you had the Neanderthal in Europe, Homo Erectus in part of Asia, and so forth.
Primitives of our own species, even today are historically shallow in their knowledge of the past. Only the poet who writes speaks his message across the millennia to other hearts.
For at least 2,000,000 years men have been reproducing and multiplying on a little automated spaceship called earth.
We are all descended from cavemen who broke the skulls of their enemies with rocks for fun or profit. But that hardly mitigates the crimes of a man who does the same thing today. I see no problem judging the behavior of the Islamic State and its apologists from the vantage point of the West's high horse, because we've earned the right to sit in that saddle.
He doesn't write like a Neanderthal. He may be a Cro-Magnon.
