Modern human begins come from a few million years ago where the life expectancy was around 30, more or less. Then, biology did not expect for the human female to reach menopause. Nevertheless, the life expectancy began to rise near the 20th century. But that is a digression.
Since it was a life of 30 years, half of that was set aside for child rearing. Do the math. Once a female had a kid or two, she didn't NEED to win another mate. |
