Ernst Mayr (1904–2005) was Professor Emeritus and former Director of the Museum of Comparative Zoology at Harvard University. For his contributions as an evolutionary biologist, taxonomist, ornithologist, as well as historian and philosopher of biology, Mayr was hailed as 'the Darwin of the 20th century'.

'In this first book of the second century of his long career, the biologist Ernst Mayr at age 100 has given us his reflections on the most interesting and important questions about life: why living things can't be understood just as very complex machines, how humans evolved, why we haven't yet communicated with any extraterrestrials, and others. Written with a clarity and vigor that shine from every page, this book is best summarized in one word: exciting!' Jared Diamond, UCLA, author of Guns, Germs and Steel (Pulitzer Prize, 1998)
