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.
Sewall Wright proposed that populations occupy adaptive peaks on a fitness landscape. In order to evolve to another, higher peak, a population would first have to pass through a valley of maladaptive intermediate stages. A given population might be trapped on a peak that is not optimally adapted.
