The question of why females mate with multiple males has long puzzled evolutionary biologists. A new study of African foam-nest tree frogs, led by University of Wollongong (UOW) researchers, reveals polyandry could be the key to reproductive success and a safer home for offspring. The findings shed light on how amphibians have evolved to protect their young in challenging environments, presenting a new hypothesis for the evolution of polyandry that ties mating behavior to the quality of nest construction.
