The question of the tempo of evolution cuts right to the heart of evolutionary theory. Emeritus professor in evolutionary biology (and a list of other disciplines) Philip D. Gingerich here takes an empirical stab at quantifying how fast evolution happens, something which has not been done very often. The resulting Rates of Evolution is a technical monograph for an academic audience that contains thought-provoking ideas.
In my recent review of She Has Her Mother’s Laugh: The Powers, Perversions, and Potential of Heredity, I mentioned how the concept of heredity has become ever fuzzier the more we have learnt about how traits can be passed to the next generation. We have come from a very gene-centric period in biology, but biologists Russell Bonduriansky and Troy Day are ready to shake up the field. Neither a Lamarckian redux nor an attempt to downplay the importance of genes, this book successfully argues that the time has come to take into account non-genetic forms of heredity. Along the way, they provide a very interesting history lesson on how we got here in the first place.
