Having originated in the oceans, land vertebrae have never completely relinquished the watery medium. The human embryo develops in a pocket of amniotic liquid, our bodies consist of nearly 95 % water at birth and 60 % in adulthood: these figures remind us of our marine origins.
The passage from aquatic to land life, the act of crawling out of the water, is the result of a long evolutionary process, made up of progressive adaptations to the initially hostile conditions of the new environment. A collective work, written by a number of experts — biologists, physiologists, physicians and philosophers — this book covers various aspects of an amazing adventure that may well not be completely over yet.
This is an illuminating, multi-facetted study of a fascinating question in human evolution.
