X and Y chromosomes: This would explain a LOT

Something else I learned from Journey of Man:

When a baby is born … the X chromosomes get mixed together every time they’re passed along. Girls get one X from Mom and one X from Dad. Therefore, the marker with which scientists would’ve been able to trace the matrilineal line geneologically back to the beginning of creation is muddled in the DNA soup. They can’t find who the original mother is — only the original father, the ancient male in Namibia from whom every human on the planet is descended.

But Y chromosomes — girls are XX and boys are XY if yall can’t remember — Y chromosomes are passed from father to son UNCHANGED. Throughout the generations. This is how they found out we’re all from Namibia.

Again: Y chromosomes are passed from father to son UNCHANGED. The X is the variable. The Y is the constant. Not sure how all men on Earth don’t all have the same Y and all look the same, but it’s something like that.

Stuff makes a tiny bit more sense now.

Bible stories about ruthless leaders killing the first-born male of every household in rival kingdoms …

God Himself even threatening the same thing

The near-worldwide cultural importance males place on bearing a son instead of a daughter …

Why men feel they have a say in women’s sex lives and reproductive rights, and why most everywhere they control it with a chokehold combination of religion and force …

All the way to the old standby headline ‘MAN KILLS WIFE AND TWO CHILDREN BEFORE TURNING GUN ON HIMSELF IN A CROWDED 7-11 PARKING LOT’ …

Yeah.

I guess men are genetically encoded to feel protective of their own blood relatives for a slightly different reason than women are.

I have no point or proclamation. No emotions to superimpose upon this fact-find I stumbled across. Just a profound sense of eureka.

... and each of them harbored their own agenda. The end

“That same night I will pass through Egypt and kill the first-born son in every family and the first-born male of all animals. I am the LORD, and I will punish the gods of Egypt. The blood on the houses will show me where you live, and when I see the blood, I will pass over you. Then you won’t be bothered by the terrible disasters I will bring on Egypt”. -Exodus 12: 13

p.s. more about the X.
