The Cambridge Social Biology Topics series comprises texts that cover elements of advanced biology that are not covered in sufficient detail in traditional texts.The Origins of Humankind is a new edition of The Origins of Mankind. The material has been updated substantially since its first edition. The text starts by explaining the theory of evolution and further chapters discuss the human journey. The text handles this material sensitively and reminds the reader that the explanations of how humans have developed over time are by no means facts. Rather, the hypotheses are continually modified on the basis of observations and evidence of human remains.
