Title: Now in its fifth edition
Review: This fascinating book is now in its fifth edition since late 2008. But somehow in the page for the fourth edition Amazon did not show this in "Other Edition". And judged from the current sales rank in May 2009, 4th edition sells much more than the 5th edition. I have not done a comparison between the two editions but you may want to check out the new edition with this link:How Humans Evolved: (Fifth Edition)
Is the review positive or negative?
