Sex and Portfolio Investment

We propose an answer to `why sex?', a long-standing question stemming from the observation that asexual reproduction is ostensibly more efficient than sexual reproduction.
From the perspective of a genetic allele, each individual bearing that allele is akin to a stock share yielding dividends equal to that individual's number of offspring. The totality of individuals bearing the allele is its portfolio investment. Alleles compete over portfolio growth. Evolutionary reproduction strategies are then seen essentially to be on-line learning algorithms seeking improved portfolio growth, with sexual reproduction a goal-directed algorithmic exploration of genotype space by sampling in each generation. We show that the algorithm of sexual reproduction yields higher expected growth than that of asexual reproduction, thus explaining why a majority of species reproduce sexually.

Joint work with Omer Edhan and Dana Sherill-Rofe.
