Canadian Scientists Find that Men are Responsible for Female Menopause
Ever wonder why the word “men” appears prominently in the word menopause? Canadian scientists may have found the answer. After decades of laboring under other theories that never seemed to add up, a team led by biologist Rama Singh has concluded that what causes menopause in women is men.
Singh, an evolutionary geneticist, backed by computer models developed by colleagues Jonathan Stone and Richard Morton, has determined that menopause is actually an unintended outcome of natural selection – the result of its effects having become relaxed in older women.
Over time, human males have shown a preference for younger women in selecting mates, stacking the Darwinian deck against continued fertility in older women, the researchers have found.
“In a sense it is like aging, but it is different because it is an all-or-nothing process that has been accelerated because of preferential mating,” says Singh, a professor in McMaster’s Department of Biology whose research specialties include the evolution of human diversity.
