This is the final of three reviews of MIT Press books in The Vienna Series in Theoretical Biology dealing with convergent evolution, something I consider to be one of evolutionary biology’s most exciting topics. Are evolutionary changes happy accidents, i.e. contingencies? Or is there a law-like repeatability underneath, explaining why some traits evolve time and again, i.e. convergence? Is it even a matter of either-or? And what lessons does this hold for life elsewhere in the universe? Philosopher Russell Powell wrestles with these questions in a manner that is as rigorous as it is intellectually rewarding. Evolutionary biologists will want to give this excellent book a very close read.
Convergent evolution was the subject of the first book I reviewed on this blog and is a topic I keep returning to. MIT Press recently published two further books on it, Convergent Evolution on Earth in 2019 and Contingency and Convergence in 2020. I felt the time was ripe to finally read their 2011 book Convergent Evolution that I bought some years ago. All three of these are part of The Vienna Series in Theoretical Biology, a series I hold in high regard. This, then, is the first of a three-part dive into what I consider one of evolutionary biology’s most exciting topics.
As mentioned previously in my review of Barbara King’s Evolving God, religion is a pervasive phenomenon, and many scholars have put forward explanations of how, when, and why it arose. The arguments King put forth did not convince me that religion is anything more than a by-product of our evolution. Apparently, so did Darwin. Though believers often like to point out Darwin was a Christian too, he struggled to reconcile the two and ultimately lost his faith. American psychiatrist E. Fuller Torrey gracefully acknowledges this intellectual heritage and here updates this idea, putting forth the convincing argument that religion arose as a by-product of brain evolution.
