Darwin and Sport

This article seems to have potential.  It discusses a connection between Charles Darwin and Sport Psychology.

Here are some of my ideas about the anthropology of sport, which I have been studying for the last 27 orbits of this planet:

1. Sports act as a metaphor for war.  We refer to athletes as soldiers, prepare offensive strikes and defend particular territory.
2. Sports establish local social hierarchies.  Sports allow people to physically dominate others.
3. Sports promote cooperation among the group.  Through teamwork, the group strives for a common goal.
4. Sports promote competition against "them".  We set up society as an us and them situation.  We will dislike the others for no reason other than they cheer for Dook, etc.
5. Sports prepare us for physical survival.  Our neuromuscular system can either leave us hopelessly uncoordinated or be honed into the physical prowess of performance.
6. Sports let us realize that we are all athletes.  Some of us have become detrained.  The 1.8 million years of human evolution left us with a lean fit body.  If we don't take care of our bodies, we lose those skills.  However, we can re-train our bodies, it just doesn't always feel good.
