OK. The environmental conditions of my ancestors selected for such things as conservation of heat, long term planning and vitamin D production. hence we tend to be more rotund, with bigger brains capable of more complex problem solving and pale skin to make the best use of the available sunlight.
the environmental conditions of african ancestors selected for such things as heat dissappation, protection from UV radiation and parasite defense. leading to leaner, narrower bodies and heads, dark skin and sickle cell trait.
of course there are many, many other adaptions. I would not do as well in africa, africans would not do as well in europe.
Almost right.
That little bit about bigger brains blah blah blah...
Your study is about harsh environments is great, so apply it. How about we break this down into base level arguments. And for the purposes of "evolution" lets talk caveman.
Are you saying the environment is not harsh in aferica?
Are you saying the aferican environment is soft?
that is your argument? both are harsh, so what's the big deal? the big deal is that they are both harsh in different ways. cold climates necessitate more planning for food and shelter, warm climates don't.
Both were harsh therefore BOTH work with your argument of "Learning capabilities enhanced in harsh environments" Level field.
ahhhh... here we go with denying reality again. do you honestly believe that living in a climate with cold and hungry winters selects for the same attributes as living in a dangerous but warm climate year round? really? come on now!
There are different dangers present in those different climates, and divergent skill sets required to live in them. You're ignoring the fact that you've got generations of handed down knowledge in dealing with one, but not the other. It is a perfectly logical counterpoint to show you where you ignore that advantage / disadvantage.
