Death of Y may spawn new human species

"She will tell the conference that new 'male making' genes on other chromosomes could step up to do the job of the Y chromosome's SRY gene, which is the key to making males male.

But this could mean men without Y chromosomes would split off from those with, eventually evolving into a new species of hominid.

"It's quite possible that you could make new hominid species that way," she says."

Early humans had sex with chimps

"Our early ancestors interbred with chimpanzees after the two species drew apart millions of years ago, a new paper suggests.

The provocative idea is sketched by US genome experts, who have discovered that hominids and chimps diverged far more recently, and over a much longer timescale, than anyone had thought.

During this time, the authors theorise, the two primates were rather more than kissing cousins: they had sex, swapping genes before making a final separation. "

I was watching a show where a doctor was saying (postulating?) that a male baby causes what he described as an almost 'antibody' genetic reaction in the mother. So each succeding male baby becomes more and more female-like, and likely to be homosexual...

(chuckle) I heard that too. The funny thing being is I'm the youngest in a family of four boys, no girls.

On one paw, I'm decidedly not gay, but neither does it freak me out like my brothers. It's like "yeah, so, not my cup of tea", but that's it.

On the other paw, I'm a Kleinfelter's moasic (85/15 XY/XXY). So I'm not exactly normal to begin with.....

...and the majority of the decendants live in the south.
