The existence of men has long puzzled scientists. Sexual reproduction is inefficient and costly, yet the majority of multicellular species opt for this method to keep their genes going. So why do men exist? Researchers from the University of East Anglia (UAE) believe they may have finally cracked it, suggesting that the evolutionary force known as ‘sexual selection’ plays a key role in improving population health and protecting us against extinction.

The study, published in the journal Nature, looked at Tribolium flour beetles to understand why most multicellular organisms rely on sex to reproduce. Under controlled laboratory conditions, researchers studied 50 generations of beetles over a ten year period and tested the impact of sexual selection. Famously theorized by Charles Darwin, sexual selection is a process whereby males compete for a chance to reproduce and females choose which male to reproduce with.

"Almost all multicellular species on earth reproduce using sex, but its existence isn't easy to explain because sex carries big burdens, the most obvious of which is that only half of your offspring—daughters—will actually produce offspring. Why should any species waste all that effort on sons?” lead researcher Professor Matt Gage, from UEA's School of Biological Sciences, said in a statement.

"We wanted to understand how Darwinian selection can allow this widespread and seemingly wasteful reproductive system to persist, when a system where all individuals produce offspring without sex—as in all-female asexual populations—would be a far more effective route to reproduce greater numbers of offspring," he added.

The researchers found that when sexual selection was removed and beetles were paired up into monogamous couples, the population's health declined rapidly and the bugs were wiped out by the 10th generation. Conversely, beetles that had a strong influence on sexual selection, where intense competition saw 90 males trying to compete to reproduce with only 10 females, were more resilient to extinction.

"To be good at out-competing rivals and attracting partners in the struggle to reproduce, an individual has to be good at most things, so sexual selection provides an important and effective filter to maintain and improve population genetic health,” saidGage. "Our findings provide direct support for the idea that sex persists as a dominant mode of reproduction because it allows sexual selection to provide these important genetic benefits."

The study suggests that sexual selection plays a crucial role in sifting out harmful genetic mutations, as competition means females are less likely to mate with genetically inferior individuals. Even after 20 generations of inbreeding, the study found that the populations that were strongly influenced by sexual selection had a higher fitness and were able to maintain population health and avoid extinction.

And to keep balance in most small societies of animals.


Plus motivation. ... males are usually the ones trying to get the nut off. You need the aggressive one..... and the nurture one after the fact.

Why does this thread exist?

"University of East Anglia (UAE)" sounds like the college of one of those princes who wants my social security number

"In 2012 the University was named the 10th best university in the world under 50 years old, and 3rd within the United Kingdom.[11] In national league tables the university has most recently been ranked 14th in the UK by The Times and Sunday Times, 20th by The Guardian and 16th by The Complete University Guide.[12][13][14] The university also ranked 1st for student satisfaction by the Times Higher Education magazine in 2013."

Is this not interesting information into why males exist? You seem to be taking it as an affront or something :heh:

This is why religion fukks your head.

You know there are species that absolutely reproduce on their own, right?

You fukking idiot. :stopitslime:

You are master of the obvious. :stopitslime: You don't need a college education to know that there are asexual species retard.
NTM, they show random female lizards on PBS that don't need males to reproduce, even the most average minds know..... But of course you feel you have some advanced knowledge when realistically your a simple minded hyper-E-aggressive basic little bytch:mjlol:

I knew when I seen you quoting me it would an insult to ME and to Religion.:mjlol:

FYI, my post has ZERO to do with religion.

I was just answering the question because idiots like you Never actually provide a viewpoint or answer.......... you just talk shyt and remain unhinged. :wow:

:wow: when the lose they close their eyes and cry^

But someone remain obsessed w a nikka:wow:


Dude is an ugly lame Beta male with 20 threads on how Atheist have it soo tough on Earth and dreams about the day that Robots take over the world , But actually this world isn't even real............ Along with genetically modified humans:skip:
