One is that males are necessary to combat disease: without sexual reproduction, a clonal species is vulnerable to increasing parasitic attack. The other theory holds that sex helps purge the species of genetic mutations by shuffling the genes in each generation.
even if sex proved to be genetically unnecessary, it still wouldn't be a total waste of energy.
It is to sex, after all, that we owe most of the things we consider aesthetically appealing in nature.
If it were not for sex, there would be no blossoms and no birdsong. A flower-filled meadow resounding with the dawn chorus of songbirds is actually a scene of frenzied sexual competition.
everything extravagant about human life, from poetry to fast cars, is rooted in sexual one-upmanship.
The author states:
First, the good news: people will still be trying to get each other into bed in 2025, ....
Having sex is too much fun for us ....
, it will be more for recreation than procreation.
AS FAR AS I CAN SEE FOR MILLIONS OF YEARS IT WAS ALWAYS FOR FUN.
IT IS STILL THAT FOR BILLIONS OF PEOPLE TODAY!
