"WHAT EVOLUTION IS is not the last book you will ever need on the subject [of evolution]. Too much jargon still clings to Mayr's professorial tweed jacket, and he's not too generous with the anecdotes and oddities you will find in most popular work son evolution. But if you approach the book without unrealistic expectations, you will find a wise and illuminating account that sorts out the complexities of evolution with insight and an authority often lacking elsewhere. The book makes some modest demands on its readers. Mayr isn't interested in an audience that won't take a little time to think. I came to think of WHAT EVOLUTION IS as a friendly textbook, less daunting and less exhaustive than the real thing, and a lot easier to carry on the subway."Mayr, Ernst is the author of 'What Evolution Is' with ISBN 9780465044269 and ISBN 0465044263.
