Readers may recall that New Scientist published an article yesterday on 13 ways we need to “rethink the theory of nature.”
Their Number 1 rethink is GENES ARENʼT DESTINY (genetic plasticity)
Most of the article is paywalled but here’s the gist of #1:
The more we learn about genetics, the clearer it becomes that “genetic determinism” – the idea that genes and genes alone fix our destiny – is a myth. A given set of genes has the potential to produce a variety of observable characteristics, known as phenotypes, depending on the environment.Michael Le Page , Colin Barras , Richard Webb , Kate Douglas and Carrie Arnold, “Evolution is evolving: 13 ways we must rethink the theory of nature” at New Scientist (September 23. 2020)
Sure but then what about the famous twin studies that were supposed to prove so much about human nature? No? Then it’s probably best for the New Scientists to just get out of the “gene for that” hell while they can.

What becomes of “natural selection acting on random mutation” if a variety of means of evolution are “natural,” mutations are not necessarily random, genes aren’t selfish and don’t come only from parents, and the fittest don’t necessarily survive? Just for a start…
