How did Pangea breakup contribute to evolution
swat32
<span>If a geological barrier (like a continent splitting apart) separates a population of primates, then each population will evolve separately to fit the different conditions of their environments.

As a hypothetical example, if one part of Pangea went north, the primates on that part would adapt to cold temperatures. If the other part went toward the equator, those primates would adapt to heat and direct sunlight. Eventually they would evolve into different species over many generations.</span>
