so today in my 1st period class we were talking about sexual reproduction, the genes, and the chromosomes
and whatnot..
then my teacher said something which was very interesting & shocking,
something that i did not know and never heard of before.
well, as we all know [or at least i would think so],
women carry XX chromosomes while men carry XY
chromosomes..and my teacher said that scientists have been researching and
the Y chromosome that men carry keeps shrinking like every year, so it's getting smaller & smaller
each year.
and the Y chromosome contains 76 genes.
anywho, so if the Y chromosome keeps shrinking then that means that men will not exist
in the future.
my teacher said that in about 125,000 years men will possibly not exist.
that is fucking insane.
how will humans or women reproduce?
i have no idea.
that is very interesting though & it's quite awkward...
