Marine study finds women suffer more injuries, shoot less accurately than men

39. I would have agreed with you in the 1970s, but now I am less sure

The main reason for the change was a set of autopsy on London Cabbies done about 20 years ago. The Cabbies all agreed to be autopsy before they died of natural causes. One of the results of those Autopsy was that the cabbies had an extra large size part of their brain that is believe to be tied in with direction. This supports the observation that your BRAIN will develop in ways that benefit you. If you need a better sense of direction, your brain will put more brain cells in that part of your brain for you are using it more. If you do not need a sense of direction, then that part of the brain is NOT developed.

This would explain men's superiority in direction. Men are NOT naturally superior in a sense of direction, but given women tend to follow our leads (look at most couples when they are in a car, it is the MAN that is driving), women do not develop that part of their brain that involved direction. As young girls they follow their parents or brothers, as young women they tend to leave their dates, and later their mates to drive and decide where to go.

Thus men playing better darts then women may go back to playing baseball as a child. Boys tend to play more baseball or simple throwing the ball at each other then do girls. Thus boys developed that part of the brain tied in with throwing and catching accurately, while girls do not for they play less such games. Thus men may be better at darts for the simple reason they developed the part of the brain that goes to accurate throwing when they were boys, while women did other activity as a young girl.

Hand and eye coordination is different. It is the use of a tool to do something. That could be using a paddle to make cake, or a bat to hit a ball. Either effort would improve that part of the brain tied in with hand and eye coordination. Chasing younger siblings could also be part of that brain development (i.e. figuring out where the kid will be not where the kid is right now when you are chasing him or her). Just a comment that hand and eye coordination would be some other part of the brain being developed as a young child, and playing at cooking thus playing at using a tool, would help someone's ability to use any tool, even a pool que.

Just a comment that it may be "Training" as a young child that is the key and the resulting change in the brain that may explain the differences more then the ancient need to hunt.
