The History of the Human Body. Evolution, Health, and Diseases

Usually, scientists look for logic and strict connections where everyone else sees chaos. Daniel Lieberman, head of the Department of Human Evolutionary Biology, comes to the opposite conclusion: the human body, the most complex biological machine in the world, appears harmonious only to the inattentive eye. For an evolutionary biologist, it is a construction of functions that do not always fit perfectly together, each of which helped solve some problem in its time. The problem goes away — the function remains.
