Books by Williams

First published in 1975, this book is a comprehensive and quantitative study of the shoot apex and leaf growth. Its central purpose is to provide precise quantitative descriptions of shoot apical systems of very diverse types.

Examining the mechanism and action of natural selection in evolution, the author offers his own synthesis of modern evolutionary theory, including discussions of the gene as the unit of selection, clade selection and macroevolution, diversity within and among populations, and other central issues.

This important landmark book shows that the evolution of the species is related to the evolution of the environment and that the reverse is also true. The environment and life developed together. There is then an intriguing problem for the long-term future of life if man changes the environment - even if only of trace (Catalytic) elements.
