Homosexuality not genetic - its epigenetic (says article)

Interesting idea- that persecution paradoxically caused propagation.

By extension- if it were no longer persecuted it would gradually die out.

In the old days you got married 'because it was the thing to do", or because you wanted children.

But now- even gays who want children can marry the same sex- and adopt.

So even it they get married thier genes would not be passed on- even if their family line and name is.

Lets just say this: its less rediculous than all of those "are we aspies the next stage in human evolution?" threads folks start here.

So - if you want to persuade a homophobe to support same-sex marriage- just use that argument! Same sex marriage will paradoxically CAUSE homosexuality to eventualy die out!

They might buy it!

Lol!

I find the Idea of Aspies as a next level of evolution intriguing, but only in part. I believe that we have traits that could be positive in human evolution, but, we have traits that would also hamper us, at the same time, if speaking in a natural selection setting. But, given our very technologically based society and its continuance to go that root, we are actually shaping our own evolution artificially, although we don't know it's actually happening. I see it more as a different presentation of give and take, I have my positive quirks that come at a cost in other places, and sometimes they cause pain and grief, but I can live alongside it. if I'm equipped to cope, I can succeed.

We on the autism spectrum are part of the genetic stock of variation that is the very stuff of evolution.
But I dont see evidence that we are either expanding or disappearing. Just remaining an endemic minority.

But if some selective force came along that favored autistic traits- then autistic traits would gradually become prevelent. You could write a sci fi novel in which autistics turned out to be better suited than nt's to live in underground caves on mars or live in hollowed out asteroids ( i dont know if they would be-lets just say they are). Space colonization of the solar system starts to move forward. Tens of millions live beyond earth in space cities or planetary colonies. Then earth gets clobbered by a supervolcanoe, or asteroied.

Generations later Earth gets repopulated by a back migration of space colonists- who are disproportionately autistic. And there you would have it - an autistification of the whole human race.

You forgot about reproductive technology such as egg/sperm donation. These methods are becoming more popular among gay couples who want a child that is biologically related to them. This opens up a can of legal worms, though.

Also, what if it is a combination of recessive traits that need certain conditions to become activated.

Whoa! Well lock up your wives and daughters!

In terms of looks, she is feminine looking. But, in attitude, she doesn't seem highly feminine to me from that picture.

I was not really making a prediction about the future evolution of human sexual orientation.

We were talking about evolution from the past to the present and how it might have been influenced (even counter intuitively) by sexual mores and cultural beliefs.

Then as an afterthought I extended his idea into the future as a thought experient.

If one really really does want to predict human evolution in the next centuries- then you're right- its anybody's guess because of the kind of thing you're talking about. The current revolution in genetic know how. Doesnt effect most people right now. But 100 years from now-who knows?

Gays siring kids via sperm doners will be least of it.

A hundred years from now- we all might have designer babies from catalogues- for all we know.
