Of all the books of recent date that try to explain what life ""out there"" ight be like, this one will make the most sense to the layman. In a free-flowing, imaginative style with touches of humor, an experienced scientist-writer discusses facts he feels are significant to speculate upon the nature of exobiology. His approach is to compare our own familiar biologic patterns of life and the environments that molded them, with the environments that must mold any life existing on the planets or elsewhere in space. So, Dr. Berrill takes us on an intriguing tour through the ""remodeling"" factory of nature--Evolution--offering a wide range of knowledge of physics and life processes that is easily assimilated, and even entertaining. In spite of the statistical possibilities of some form of life existing elsewhere in the universe, he makes it very clear that our earth is one of the most satisfactory places for the evolving forms of organic nature to have arises.
