'In 2006, Rudie Botha launched an all out attack on the legitimacy of the claim that the South African archaeological site of Blombos had evidence of 'fully syntactic' language 75,000 years ago. No one has been able to counter the logic of his argument, and this book applies that same relentless, illuminating logic to other claims in the study of language origins. In doing so, Botha shows just how carefully any claims must be justified, and just how powerful his Windows Approach is. Students and researchers in archaeology, primatology, linguistics, and comparative ethology cannot ignore this book.' Iain Davidson, University of New England
'This book will prove to be a milestone in the field … a meticulous, rigorous, and yet highly readable guide.' Paul T. Roberge, University of North Carolina, Chapel Hill
