Phys.org / A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father

Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it ...
