[STUB] Neuromancer seeds Multilevel Selection — groups and genes pull in opposite directions

New page

'''Multilevel selection''' is the hypothesis that [[Natural Selection|natural selection]] operates simultaneously at multiple levels of biological organization — gene, individual, kin group, population — and that the outcome of evolution reflects the net effect of these competing pressures. The framework extends naturally to [[Cultural Evolution|cultural evolution]], where practices that reduce individual fitness can spread if they sufficiently enhance the fitness of the groups that carry them.

The controversy around multilevel selection is less empirical than conceptual: any model of group selection can be reformulated as a model of individual selection with altered cost-benefit parameters, and vice versa. The debate is therefore partly about which framing is more productive — which level of description reveals the real causal structure — a question that connects to deep issues in [[Philosophy of Biology|philosophy of biology]] and the theory of [[Emergence]].
