(I will leave you to imagine a world without men, but there is one immediate benefit from their extinction. Adam's curse is permanently lifted. Sexual selection disappears, for the simplest of reasons - there are no longer two sexes. Sperm no longer fights sperm for access to eggs. There are no sperm to do battle, no Y-chromosomes to enslave the feminine. The destructive spiral of greed and ambition fuelled by sexual selection diminishes and, as a direct result, the sickness of our planet eases. The world no longer reverberates to the sound of men's clashing antlers and the grim repercussions of private and public warfare.)
