conference paper description
For a population to undergo evolution by natural selection, it is assumed that the constituents of the population form parent-offspring lineages, that is, that they must reproduce. I challenge this assumption by analyzing the notion of reproduction into two sub-processes that produces parent-offspring lineages between the parts of a population, that is multiplication and inheritance, and show that their population-level roles, generation and memory respectively, can be effected by processes that do not rely on such local. I further argue that these two population-level processes are necessary conditions for a population to undergo Darwinian evolution, not local parent-offspring lineages.
