The Basis of Evolution was published by Christian Anfinsen in 1959. |
And finally, Anfinsen tied protein chemistry, genetics, and evolution together. He wrote, “The principle aim of this book has been to examine the basic principles underlying another possible method for the study of evolution (instead of fossils or comparative anatomy). This method is based on the hypothesis that the individual proteins which characterize a particular species are a unique reflection of the genes which control their synthesis….The structure of proteins may be a relatively direct expression of gene structure and…comparative protein chemistry may furnish a qualitative view of genotypic differences and similarities.”
