A smart, provocative and wonderfully accessible look at a new and controversial area of evolutionary science.
This book is about a simple measurement of the human hand: the 'finger ratio', or the length of the ring finger relative to the index finger. John Manning uses a tiny difference between the sexes - that men tend to have a greater finger ratio than women - to examine a dizzying group of questions about human behaviour, from sexuality, to musical ability, to predisposition to disease. Controversial, but unfailingly clear and balanced, John Manning's cutting-edge research poses many fruitful questions about what makes us as we are.See all Product description

"the finger ratio might make you this - or might make you that"
The research is tame with very small sized research groups and most of the conclusions he draws are from a selection of his unpublished studies.
The most frustrating part is that few of his findings are supported by facts or statistics just platitudes such as "a large number" or the "largest proportion" so we're left wondering how conclusive are or were were the studies he describes.
I have read this after reading the much more informative and rigourously preparred "Bad Science" book and I'm sorry but unfortunately Prof Mannings is an example of - just bad science.
