University of Rochester researchers developed a new evolutionary model that suggests human intelligence developed to meet the demands of our infants, in a self-reinforcing cycle: bigger brains led to shorter pregnancies, requiring parents to have even bigger brains.
A study of 986 Bolivian women found that on average, a lifetime infection with a type of roundworm named Ascarius lumbricoides led to an extra two children in the family. Their paper, published in the journal Science, suggests that the worm is altering the host’s immune system, making it easier to become pregnant — in effect, the parasite increases female fertility. The researchers hope this discovery will lead to “novel fertility enhancing drugs.”
