In attempting to understand why men exist, researchers from the University of East Anglia wanted to know “why sexual selection – whereby men compete and women choose their partner for reproduction – actually occurs.” Their findings, published in the science journal, Nature, state that they believe sexual selection “helps to maintain health in the population and protects against extinction.”

As a takeaway quote, this is certainly a worthy topic for conversation: “In the absence of sex, populations accumulate deleterious mutations through a ratcheting effect where each new mutation takes a population closer to extinction. Sexual selection helps to remove those mutations, enabling populations to persist against the threat of extinction.”
