Figure 1. Alternative evolutionary paths from a state of biparental care and moderate sexual selection to a state of uniparental care (in this example, female only care) and intense sexual selection acting on the noncaring sex. The first evolutionary path ((a)–(c)) involves initially a transition in the type of care, from biparental to uniparental, followed by a transition in the intensity of sexual selection acting on the noncaring sex. This follows what would be predicted by the parental investment hypothesis. The second evolutionary path ((d)–(f)) conversely, predicts first a transition in the intensity of sexual selection acting on one sex, followed by a transition in the care-type. This follows what would be predicted by the sexual selection hypothesis.
