Here and welcome to another edition of the Art of Manliness podcast.

So one of the things that makes humans well human is the ability to make a fist.

Other primates can't do this.

The commonly accepted theory is to why humans developed this ability to make fist that

needed to do so in order to grasp tools.

But research conducted by my guests today have led

into positive, very different theory.

They argue that one of the reasons we can make a fist

is so that we can give better knuckle sandwiches.

That's right, we have a fist so we can punch.

Their names are Dr. David Carrier and Dr. Michael Morgan.

Dr. Carrier's Professor of Evolutionary Biology

at the University of Utah.

And Dr. Morgan is an emergency room physician.

When Dr. Morgan was an undergrad at the University of Utah,

he worked with Dr. Carrier on two papers

to explore the role of physical aggression,

what it may have played in the development of the human fist.

Today on the show, we discuss that idea

and the theory that human bodies, especially male human

bodies, evolved for fighting.
