Reinventing Darwin,Ā Niles Eldredge
The most prominent phrase in this book by far is “we naturalists”, which I think demonstrates pretty well the ideological stance of the author. Niles Eldredge begins by setting the scene: the “naturalists”, people like himself and Stephen Jay Gould, vs the “ultra-Darwinists”, like Dawkins. The naturalists have a more nuanced view of natural selection, while the ultra-Darwinists think selection occurs on genes and genes alone (according to Eldredge). This book is a debate about the fine details of natural selection, not about whether it happens: “Darwin demonstrated without a shadow of a doubt that natural selection is an ineluctable law of nature” (p.12), “No one doubts that Darwin’s theory of evolution by natural selection is correct” (back cover) — so if you’re in any doubt about evolution itself, this won’t convince you.
I don’t know whether science has sorted out a lot of this dichotomy yet, or whether you don’t see it at BSc level, or if the structure of the Open University is such that you happen to get exposed to both views, but I didn’t think of the debate in these starkly delineated terms at all. I’ve been taught principles espoused by both sides, in a kind of synthesis. Of course, it probably also helps that I’m coming in from outside, but either way, I see value in both sides of the debate.
Eldredge manages to beĀ reasonably even-handed, despite the “we naturalists” refrain, and sets forward a good case for species sorting, punctuated equilibria, stasis, etc. Even though my training leans toward the genetics end of things, because I find the biochemistry fascinating and ecosystems less so, I can’t think of anything I vehemently disagreed with, except that refrain of “we naturalists” — which started to come across as needlessly divisive, given that plenty of people sit somewhere in between.
Of course, this is from 1995, so it’s not the most up-to-date text; to me, it was kind of interestingĀ because it fossilised attitudes at the point Eldredge was writing. I don’t think anything in it was new, surprising or controversial to me. The style was rather dry and repetitive (we get it, we get it, “you naturalists” are not denying natural selection); I’m told Gould was a better prose stylist, so that’s probably where I’ll turn next.
I’m told that there are still problems with geneticists just ignoring the whole of palaeontology with regard to evolution but also that the problem appears to be slowly eroding away since Dawkins’ ultra Reductionist viewpoint was conclusively proved wrong by the development of neo-epigentics. It became impossible to reasonably hold the view that all you needed to know was the sequence of base pairs and the “law” of natural selection – a view that never held water anyway as it totally ignores the emergent phenomena of ecology and the idea of arbitrary catastrophic de-selection. But since *molecular biologists* developed epigenetics it couldn’t be ignored by genetic evolutionary theorists…
This whole saga shows both the weaknesses of Reductionism in science and that one ignores or arbitrarily dismisses everybody outside one’s own narrow discipline at one’s peril. It’s a real shame that Gould didn’t live to see the current state of the field.
And speaking of Gould, he was a great scientist and excellent popular writer on his own field, the practical challenges of modern scientific debate and proper scientific method (unlike Dawkins).
