Anthropology

[In this book, the authors] are interested not only in what humans are and were like; [but they are] also interested in why they got to be that way, in all their variety. When there are alternative explanations, [the authors] try to communicate the necessity to evaluate them logically as well as on the basis of the available evidence. Throughout the book, [they] try to communicate that no idea, including ideas put forward in textbooks, should be accepted even tentatively without supporting tests that could have gone the other way. -Pref.
