I’ll keep this short for today, although maybe I’ll discuss more — origin and implications — in a future post.
Basically, I was thinking about women’s equality, which led me to think more broadly about gender differences in humans, in general. And I realized something that’s probably obvious, but not intuitive.Genetically, men and women are significantly different. Duh! But let me explain.
Genetically, men and women differ by a Y chromosome, although there are genes on the Y chromosome that are shared on the X chromosome also. So let’s estimate that 1/2 of the Y chromosome is unique to men. That’s 1/2 of 59 million base pairs or, to make calculations easier, 30 million base pairs. Now, the human genome is about 3 billion base pairs long. That suggests that men and women differ by about 1% of their genome.
Doesn’t sound like a lot, does it? But wait.
A human genome differs from that of a Chimpanzee of the same gender by 1.2%. That means that you are about as similar, genetically, to your spouse as you are to a chimpanzee in the local zoo!
That could go a long way in explaining why men and women don’t understand each other.
Insight and longevity.
