Many neo-Darwinists treat natural selection of genes and individual or
ganisms as broadly equivalent. This enables Wilson & Sober (W&S) to pr
opose a multilevel group selection model by drawing parallels between
individuals and groups. The notion of gene/individual equivalence is a
profound misconception. Its elimination negates W&S's current approac
h but offers the best way forward for both life and behavioural scienc
es.
