We hear that fish and other marine creatures are migrating north because the water is getting warmer and is thus not the correct environment for them. One assumes that this is an instinctive reaction, part of the evolutionary way that life forms manage to survive.
Given our far greater intelligence, why then did Man stay in areas of the world such as Africa where drought and famine are rife? Those parts of Asia where flood and severe weather is common?
Current thinking is that Man first existed in Africa and that, thus, some of the species DID move to more suitable climes. What caused the rest to stay? Did Man evolve into two (or more)slightly different forms? Is African man, or Asian Man, EXACTLY the same species as European Man?
I am not asking for theories, but for a pointer to some work of reference where I can find out what current thinking is.
