Male faces 'evolved to take punches'

[BKM-2010]

I always suspected that a big jaw, chin and brow ridge help absorb punches better. But I doubt they help as much as a strong, thick neck, And there may also be something in the skull structure that helps prevent the brain from shaking after a punch.

Dwyane Wade must have a Margarito chin then.

Saw this on BBC news today, thought it was of interest to the fight fans here:

A new theory suggests that our male ancestors evolved beefy facial features as a defence against fist fights.

The bones most commonly broken in human punch-ups also gained the most strength in early "hominin" evolution.

They are also the bones that show most divergence between males and females.

The paper, in the journal Biological Reviews, argues that the reinforcements evolved amid fighting over females and resources, suggesting that violence drove key evolutionary changes.

Fossil records show that the australopiths, immediate predecessors of the human genus ****, had strikingly robust facial structures.

For many years, this extra strength was seen as an adaptation to a tough diet including nuts, seeds and grasses. But more recent findings, examining the wear pattern and carbon isotopes in australopith teeth, have cast some doubt on this "feeding hypothesis".

"In fact, [the australopith] boisei, the 'nutcracker man', was probably eating fruit," said Prof David Carrier, the new theory's lead author and an evolutionary biologist at the University of Utah.

Masculine armour
Instead of diet, Prof Carrier and his co-author, physician Dr Michael Morgan, propose that violent competition demanded the development of these facial fortifications: what they call the "protective buttressing hypothesis".

In support of their proposal, Carrier and Morgan offer data from modern humans fighting. Several studies from hospital emergency wards, including one from the Bristol Royal Infirmary, show that faces are particularly vulnerable to violent injuries.

"Jaws are one of the most frequent bones to break - and it's not the end of the world now, because we have surgeons, we have modern medicine," Prof Carrier explained. "But four million years ago, if you broke your jaw, it was probably a fatal injury. You wouldn't be able to chew food... You'd just starve to death."

The jaw, cheek, eye and nose structures that most commonly come to grief in modern fist fights were also the most protected by evolutionary changes seen in the australopiths.

Furthermore, these are the bones that show the most differences between men and women, as well as between our male and female forebears. That is how you would expect defensive armour to evolve, Prof Carrier points out.

"In humans and in great apes in general... it's males that are most likely to get into fights, and it's also males that are most likely to get injured," he told BBC News.

Long-running debate
Interestingly, the evolutionary descendents of the australopiths - including humans - have displayed less and less facial buttressing.

This is consistent, according to Prof Carrier, with a decreasing need for protection: "Our arms and upper body are not nearly as strong as they were in the australopiths," he explained. "There's a temporal correlation."

The facial buttressing idea builds on a previous observation by Prof Carrier and Dr Morgan that the early hominins were the first primates to evolve a hand shape compatible with making a fist - and thus, throwing a punch.

That earlier paper attracted criticism from some other researchers, and Prof Carrier expects this new contribution may also prove controversial. He says that debate about the role of violence in human evolution is not new.

"[Our paper] does address this debate of whether our past was violent or peaceful," he told the BBC. "That's an argument that's been going on for a very long time."

"The historical record goes back a short time, the archaeological record goes back a few tens of thousand years more... But the anatomy holds clues to what selection was important, what behaviours were important, and so it gives us information about the very distant past."

Has anybody told Amir Khan?

[Biolink]

of course they did. that's intuitive.

women today aren't attracted to the whole caveman look, but they appreciate a sturdy chin and set of cheekbones.


primates are f#cking violent. men fight. it's in our nature.


that modern men are largely nonviolent is a conventional phenomenon. i blame squeelpig.

But for the most part they still are doe. A guy with a nice fit body still has the advantage over a skinny hipster looking dude in most settings.

HGH

there are lots of muscles in the face, bro. the neck, too.

most naturally strong dudes have jaws that look like they can open cans.



plenty of studies have been done that demonstrate an ability for men and women to diagnose the upper body strength of men based on looking only at the face.


strong faces, strong dudes.
