This book grew out of the bewilderment of one of the authors, w<br >has no formal training in evolutionary science, at the lack ofrespol<br >from those who have had such training to the fascinating work<br >Vificent Sarich and Allan Wilson, of Berkeley in California. and th<br >colleagues. The work, published in widely read and respecta[<br >scientific journals such as Nature and Science, is about the origin al<br >evolution of all living things. That means it is about mankind. [<br >studying the molecules of life from living species, rather than tl<br >preserved fossil remains of extinct ones, Sarich and Wilson showe<br >is long ago as 1967, that our kinship to the African apes is mu~<br >:loser than any mainstream palaeontologist has ever acknowledgec<br >Fo an astronomer with an outsider s interest in the subject, th<br >vidence seemed dramatic and important enough at least to caus<br >xcited debate among the experts, yet each paper in the journal<br >eemed to sink with scarcely a ripple of interest. The new picture o<br >uman origins raised novel and interesting questions, as well a<br >-*solving old puzzles, and it portrayed an inherently interestin~<br >abject - ourselves.
