““If you had no variation at all, you wouldn’t get evolution,” Petrie told LiveScience.”

I don’t see any sign of evolution in modern man.

How about because people have varying concepts of "beauty?"

What is attractive to one, could be ugly to another (for animals).

Add onto this humans, who hopefully are not so base that all humans marry based on physical appearance.

Ugly people don’t get the chance to reproduce as much........

For some species, females select the most attractive males to mate with: female peacocks will choose males with the longest tail feathers—the peacock version of George Clooney.
 

This should never be mentioned without referencing Zahavi.

Angelina Jolie’s pouty lips

She wasn't born with them either.

My oh my, how educated these dumb people are.

This is easy: once upon a time, God ordained that::

“There shall be an Ass for Every Seat!”

And people have been obedient to that law since time began.

Sheesh

As a seventy plus year male, I have been puzzling over this for many years. I very much appreciate this information.

As my statistics professor once put it:

“The normal curve is a cruel b!tc#.”

But clearly this isn’t the case: for every Johnny Depp out there, there’s a George Costanza—in humans, birds and other animals alike.

Well! There's your proplem. I think George Costanza is WAY sexier that prissy, scary, Johnny Depp.

It all comes down to individual brain wiring. I tend to select my mates by there testosterone, sweat and agression and not their pampered, soft-handed good looks.

Well that study doesn’t apply to me, so I’ll skip this thread.

We don’t all drink beer all day.

That would fix it...:)

[ArGee]

The answer is easy.

We think we know why animals pick a mate.

But we really don’t.

We just think we do.

That’s probably the case for much of biology.

Shalom.

In some of her earlier work, Petrie showed that men with greater genetic diversity in areas of the genome relating to disease defense were also rated as more attractive by women.

Bodies better at killing bacteria smell better.

I believe the point of the research is this:

Beautiful people are more likely to possess/carry genetic (DNA) mutations. Nature wants these subtle mutations, so it makes the carriers more attractive and more likely to mate more often.
