• New research suggests that we need men because of the process of ‘sexual selection’, where they improve the gene pool by competing to be chosen by females for reproduction.
• Scientists have been long puzzled by man’s continual existence through evolutionary selection given that their only contribution to reproduction is sperm and that a system that produces offspring without sex (such as an all-female asexual populations) would be more efficient in this regard.
• Research performed by Britain’s University of East Anglia revealed that the gene pool and population health is improved through competition, whereas a lack of competition would result in weaker genetic populations which are then at risk of dying out.
• Matt Gage who led the study noted that sexual selection acts as a filter to remove harmful genetic mutations which help populations flourish in the long term and avoid extinction!
• The research was published in the journal Nature on Monday.
