as sanpaku pointed out upthread: mitochondrial DNA is strictly matrilineal. that is, it has its very own DNA, outside the nucleus, and it only gets passed from mother-to-offspring. similarly, Y-chromosomes only come from dad (whereas X chromosomes can come from either parent).
if you evaluate the genetic variability of Y-chromosomes and mitochondrial DNA, it would seem that mitochondrial DNA exhibits more diversity than Y-chromosomes*. thus, we conclude that more women have been contributing their unique mitochondrial genes to the pool than have men and their unique Y-chromosomes. s
o basically most babies were made by one guy and a lotta chicks
*nb - i am just parroting sanpaku on this. i've never heard this stat, and have neither reason to doubt it, nor to believe it. that being said, it doesn't seem shocking to me at all to learn that back in civilization's small times, ~alpha males~ (or w/e) made more babies (via polygamy, harems, and/or rape). i should also point out that mitochondrial DNA is subject to different selective pressures than Y-chromosomes. that is: if 1000 couples have 1000 babies, 1000 of those babies will inherit their mom's mitochondrial DNA, and only half will inherit their dad's Y-chromosomes. kinda spit-balling here, but one could see how that might result in a diversity of maternal DNA, and a relative narrowing of the uniquely-male contribution. could be rong tho, I Am Not A Geneticist

They would probably say "sweeeet this means the second coming is around the corner, now all that has to happen is the prophet gets shot in the middle east and that rock on the conference center breaks open, Jesus #1"

Funny, yesterday I googled Polyamory, and every 2guys/1girl scenario starts out a fair description of the pros and cons, personal tales, individual situations, all of them ended up describing "doubel pen", let's call it that...

I kind of think polyandry is cool NOT because I am interested in it, but because it is practiced by magpies. And magpies are probably the best creatures on earth!
