Thats not how it works. Human population because it has no predators grows rapidly until it reaches it’s carrying capacity. Carrying capacity is high in a place with lots of food, living space, etc and low in a place like a desert.

You are thinking of exponential growth when population is actually logistical growth.

Could be. But, given a large enough area and the fact that any destructive threat would be localized, I would think that, over the space of a continent, the population would be densest where it is oldest. Locally, I think you are correct but, continent wide, I think the total population would be able to overcome local destructive events. Also, using birthrate data, the population should be multiples higher over a 25 million year time period. Geometric, linear or localized. We've doubled the world's population in my lifetime (according to the UN) and I'm simply not that old!

I'm curious to know if anyone has OBJECTIVELY modeled human population growth from the pre-historic period to present. If OBJECTIVE analysis could possibly be used in this highly political field, it may shed some scientific light on the theory.

Also, why would humans emerge from a desert unless stress makes them think better to survive.
