DZ said:It's been known that most of male (Y) chromosome genes has already
been lost during evolution leading to modern humans and it would be
already extinct if not for the event when once it was "saved" by an
abberant addition from a non-sex chromosome. The female chromosome X
has been stealing up the genes from Y even including sex-determining
genes like SRY. Dr Jennifer Graves says the wimp Y is running out of
time. At the rate it's losing its genes now there'll be no genes left
in 10-45 mln years.
It's also quite probable the species wont exist at all in 10-45 mln
years, so we have plenty of things to worry about between now and then.
