Dear Mr. Darwin, You may find it presumptuous of me, if not a little macabre, that I should take up my pen & write to you more than 100 years after death . . . So begins a correspondence -- from a 21st-century geneticist to the author of On the Origin of Species, first published in 1859 -- debating the surprising findings of modern genetics & their influence on the evolution of biological novelties, from genes to organisms to human nature. Author Dover sets up a lively & stimulating discourse. From junk DNA & selfish genes to the position of the individual organism at evolution s center-stage, this book illuminates some of the most complex theories of contemporary biology & Dover s own original view of evolution in a uniquely compelling & readable way.
