'In this book Dr Finlay takes several examples to illustrate our evolutionary tree at the molecular and genomic level. Step by step he provides a wealth of cumulative evidence that demonstrates how our genomes are related to other primates and to our more distant biological relatives. The evidence is compelling and shows the elegant ways in which we are connected to the rest of biology. Nonetheless we are more than just intelligent apes, and Finlay is careful to emphasise that our genomes are only part of the story of what it means to be human and that we have also been shaped by historical, cultural and religious factors that may not affect our physiology and anatomy but define us a human beings.'
