Science Masters: Plan And Purpose In Nature

George C. Williams explains how evolution can produce remarkable adaptations in the natural world, and examines how the same process can also produce design flaws that can cause serious problems in living things - including in human beings.

Plan and Purpose in Nature is a brilliant survey of Darwinian evolution in the natural world. It tells the story not only of the wonderful adaptations which the process of the natural selection produces throughout nature,but also the limitations of evolution for the 20th century human beings,which environment and diet have changed drastically while their biology and psychology have not.
