Fish are what made our brains evolve, not mushrooms lol. In fact, humans will probably never lose their attraction to shiny things, particularly men. It's so embedded in our reptilian brain and useful just in case we do see the end of our civilized world.
And what does it matter what skin color we started with? Though I think skin color has always been as diverse as it is now, because humans didn't all originated in one place. It's not like a switch flipped and suddenly everyone's walking around. Everything adapted by our ancestors wasn't exclusive to one group of people in one specific region. People traversed the landscape way back then, and as such met new groups of people and things were shared and spread out among many different peoples.
Yes, the popular opinion was that Africa was the cradle of our evolution - but the climate there wasn't as it is now. One of the theories for why we are bipeds now is because we often reached for food in trees rather than climbing them. This hints at abundance, which further illustrates that in fact it wasn't a hot, dry or desert landscape that would dictate our skin color.
Then again, I personally don't believe Africa was where everything came from - I think that is where the evolutionary process was most dominant but I believe human evolution was a global phenomenon, nature's plan is something we've never been able to figure out.
Then let's not forget about the extinct Neanderthals - what skin color were they? Evidence dictates that both Homo neanderthalensis and Homo sapiens neanderthalensis co-existed and were somehow on the same evolutionary scale....
All this stuff is very thought-provoking
