Penile spines – which make the penis more sensitive and speed ejaculation – are more common in animals that face intense competition for mates, and where females are likely to mate with many males in rapid succession. The loss of penile spines may have allowed our ancient ancestors to copulate for longer, a development thought to have nurtured monogamous couples and paved the way for more complex social structures.
