The variability of man

[GOD]

I read something quite interesting about IQ and the sexes, basically to see whether there was any substance behind the notion that men score better in IQ tests than women etc.

One very surprising fact I uncovered is that while men and women tend to have the same mean intelligence, males have a wider spread (The bell shaped curve is flatter). Hence, this would indicate that some men are more "intelligent" in larger quantities than women, but also at the same time there are more men lower than women.

The hypothesis being that males carry the greatest genetic variability and while there are more negative handicaps there are also more positive "handicaps". Hence, any benefits could be passed amongst the general population faster as males can impregnate more females.

This also sums up what I'd always thought, males are the wild card XY and females the safe bet with ** which averages genetic differences.

Just so damn interesting!

Slightly off centre but interesting to note:

Excerpt: "THE male *** chromosome appears to have saved men from a rare but debilitating brain disorder passed down to women only.

Australian researchers have become the first to unearth the genetic cause of a hereditary disease that triggers epilepsy and intellectual disability in the female line of families. "

Gotta admire the complexity and cleverness of our existence, the survival of the species and all that-brilliant bit of creative footwork.

Thats is one exception to the commonly regarded rule that women are less prone to genetically problematic issues because one X can cover off any problems with the other X. Whereas Men are out of luck because the X and Y don't cover each other off.

We all probably remember those sniff tests when women selected blokes based on their differences in body odour... well, given her children (esp the daughters) are most likely to gain from a completely different X from the father, then she would be more likely to have a healthy baby. Not so sure about the male (as the father versus having a son) I guess it works for the father because he's more genetically orientated to having as many kids as he can muster. Its the usual natures quality v quantity game. (men quantity, and women quality).

I remember reading about how feminised men actually have very feminised daughters. However, I believe the "gay" gene is just the migration across sexes (As I believe there are major genetic rifts that play themselves out over generations).

Another thing that I noticed once was the reported offspring of Chief Exec's in the largest listed companies in Britain, it was really strange to see that they had 2:1 in favour of girls (The book wasn't about that, but I just curiously added up the ratio's of their reported offspring).
