Simon Baron-Cohen's book Zero Degrees of Empathy.
I reviewed this book for the Guardian
Baron-Cohen's book The Essential Difference is also a "must read" book. It should really be on the national curriculum, we should all be learning this stuff at a young age. The Essential Difference will teach you a great deal about yourself and about those you know. Get someone to buy it for you for xmas.
My book remains a really good read; there is a lot of finely interwoven context enabling the big-picture to the fascinating world of female dominated primatology to be told.
BEATRIX CAMPBELL, SCOTLAND ON SUNDAY'...a book in which journalism and scholarship unite in a riveting insight into a new branch of knowledge...'
(My Darwinian vampire novel, "Worth Their Weight in Blood" will be published in 2012 & will also be "riveting" - check this page for up-dates.)
The Third Chimpanzee is fabulous, you must read it! Diamond's book does a great job of contextualising evolution.
Frans de Waal’s The Age of Empathy is also a wonderful read.
Paul Stewart's book Galapagos - Islands the Changed the World, is a spectacular book, full of amazing photographs and a full historical and scientific appraisal of Darwin and the Galapagos Islands, value for money here.
