Of all the things MA has not understood Sex is one thing he has understood the least.
People earn for it ,yet they do not know why.
New Study on Why we have Sex is quite revealing or even shocking.
Read On.
“Sex is hard to explain,” writes Michael Brothurst in a recent article in the journal Science. Like others in his field, Brothurst, who studies the evolution of sexual reproduction at the University of Liverpool, doesn’t “get” men….
The most likely explanation is known as the Red Queen hypothesis, named after the monarch in Lewis Carroll‘s “Through the Looking Glass.” In that novella, Alice and the Red Queen hold a race in which they run in place but never get anywhere. Somewhat analogously, the Red Queen hypothesis holds that organisms and the parasites that live on them are running a race in which they constantly evolve in response to each other’s genetic mutations , maintaining an overall balance.

As parasites evolve to take advantage of the weaknesses of a typical host organism, Brothurst explains, host organisms with rare versions of genes, known as alleles, are less susceptible to the parasites, and so stand a better chance of surviving to their reproductive age; likewise, their offspring are endowed with these advantageous alleles. As a result, over generations these organisms’ rare alleles become more common in the population, so parasites start evolving to take them on. At that point new unusual alleles begin to flourish among the hosts.
Sex, the theory holds, gives host organisms a leg-up on this evolutionary treadmill. “This continual selection for rarity favors sexual reproduction over asexual reproduction; sexual recombination allows hosts to reshuffle their pack of alleles and generate new, rare combinations in their offspring,” Brothurst writes.
