right handed 100,000 years ago.

sex on the wrong brain theory suggests it makes a difference which side of the brain we associated sex with - which hand.

right hand to left brain increased greed, fear, and the need for certainty (absolutism, bigotry, patriarchy, suspicion, lack of empathy, etc) , and that was a an advantage in times of conflict as populations increased. in the last few thousand years as populations and 'civilizations' grew they began to delay the age of reproduction sex on the wrong brain got worse.
