In humans, our adaptive traits are particularly fascinating because they span such a wide range – from the way we think and behave to the very functioning of our bodies.
In 1962, human geneticist James Neel proposed the thrifty gene hypothesis. According to this hypothesis, so-called “thrifty genes” evolved in some human populations because they allowed people to get by on fewer calories and store the rest as body fat when food was plentiful.

Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.
