摘要

Sex is a costly form of reproduction compared with parthenogenesis, but sex persists because of the more resistant and competitive descendants that it produces. We obtained thelytokous offspring from unmated female Doru lineare (Eschscholtz, 1822) earwigs, a species of insect in which parthenogenesis has never before been reported, and found that their number and survival rate did not differ from offspring of mated females. Current hypotheses support advantages of sex or parthenogenesis, but never equilibrium between them like the one reported in this paper. We suggest that parthenogenesis is how females multiply their entire genome and renew themselves.
