Answers. It was Charles Darwin who highlighted the reproductive advantages of environmentally adaptive traits. One of the most important naturalists, he studied evolution and is the one who devised the theory that we and monkeys have the same ancestor.
Adaptive traits, such as skin color, have frequently been used to define races in humans, but such adaptive traits reflect the underlying environmental factor to which they are adaptive and not overall genetic differentiation, and different adaptive traits define discordant groups.here are no objective criteria for choosing one adaptive trait over another to define race. As a consequence, adaptive traits do not define races in humans. Much of the recent scientific literature on human evolution portrays human populations as separate branches on an evolutionary tree.
