The first book on Evolutionary Developmental Biology that is for undergraduate and general readership.This is the first book on the new field of Evolutionary Developmental Biology that is aimed primarily at an undergraduate and general readership. It focuses on the question of how embryonic development changes in the course of evolution, thus giving rise to new types of creatures. It takes the controversial view that biases in the ways that embryos can be altered are just as important as natural selection in determining the directions that evolution has taken, including the one that led to the origin of humans.This is the first book on the new field of Evolutionary Developmental Biology that is aimed primarily at an undergraduate and general readership.
