In this volume, the product of decades of study and research, the
world's foremost geneticist surveys the major developments in what is
emerging as the most important single area of scientific inquiry in the
twentieth century: biological theory of evolution in particular.
Noting that the theory of evolution in biology is more than a century
old, Dr. Dobzhansky points out that it is nevertheless only in recent
times that our knowledge of its physical basis as well as our
understanding of its dynamics has progressed greatly. Yet, he notes, new
problems have replaced the older ones at the forefront of scientific
inquiry, problems which require entirely new approaches. It is to these
manifold and exciting new questions that the author brings a lifetime of
experience.
Throughout, his goal is to create not a summary of all the available
literature, nor a professional book written only for the scientific
community, but rather a presentation of basic ideas, accompanied by the
indispensable references which would enable interested readers to pursue
the matter further. The book has been purposely kept short to enable it
to be read as a whole, and above all, it has been written in a manner
which will hold the attention as well as inform both the general reader
and the professionally concerned scientist.
