Researchers have analyzed the genomes of thousands of women in the UK and the Netherlands to measure the extent to which a woman's genes play a role for when she has her first baby and how many children she will have. Significantly, they have found that some women are genetically predisposed to have children earlier than others, and conclude that they have passed down their reproductive advantage to the next generation.
