History of evolution

By evolvingthoughts on July 15, 2008.

Ryan Gregory at Genomicron has a couple of interesting posts; One on Natural Selection before Darwin, which discusses prior presentations back to Hutton. I think he's right that prior to Darwin selection was typically not thought of as a way to form new species. It's generally not after Darwin either - speciation is usually thought of as a side effect of selection. Also he argues that abiogenesis, the formation of life from abiotic materials, is a part of evolution, but not required by evolutionary theory. I agree: but not because abiogenesis begins with replication. Rather, I think replication is itself the outcome of selection on chemical autocatalysis. Finally, he argues that epigenetic evolution is not Lamarckian, something else I agree with.

Also note that the journal Evolution and Outreach has a new edition - free to view.

Myth 6: Darwin thought everything was due to natural selection
Darwin's Dangerous Idea, according to Daniel Dennett in the book by that name, is natural selection. This is often referred to as "Darwin's theory". But Darwin did not always think evolutionary events or processes were due to natural selection. First off, let's say this again: Darwin did not think…

Fodor on Natural Selection
Philosopher Jerry Fodor offers up the latest example of a familiar genre: essays declaring the forthcoming demise of natural selection, coupled with very little in the way of supporting argument. He is writing in the London Review of Books. There's quite a bit I find wrong with Fodor's essay. In…
