Molecules and evolution

the long version

"A definitive statement of the chemical basis of evolution, this book describes in detail the present knowledge and success that science has acquired in deciphering the evolutionary history of living organisms. This book places major emphasis on the concept that the number and sequence of chemical bases in molecules of DNA are a cryptogrammic record of the evolutionary history of each species. The solution of the cryptogram and the evolutionary history of each species come from the study of proteins and the genetic code"--Publisher's description.
