Aliens and asexuality

Ok I'm going to try this again! Being that this was the post I had to re-write.

You're probably wondering what Aliens and asexuality have in common but pull up a chair and read on and you'll hear the interesting storyline that happened between a coworker and I :P

A coworker of mine listens to a radio broadcast in the evenings called coast-to-coast on AM radio. This particular show has a lot of guest speakers on and some of which can be pretty wacky. Anyway, one evening they had on a scientist who was trying to explain why alien encounters all over the world seem to all describe a similar being. There have been scientists who found people with no or very limited access to media ie they've never seen alien pictures of the typical "grey" people describe and yet these people still described very closely the same being. They all seem to describe a genderless, non-featured being that is grey, big eyes and less than 5 fingers.

Well the scientist stated that since the Y chromosome the (male) one was going away in nature in humans that eventually the X chromosome would take over and thusly humans over a million years or so would become asexual and genderless much like the aliens people describe now when they claim to have had an encounter. He came to this conclusion due to the lack of Y chromosomes in humans out there today. I can only guess he means the 52% female to 48% male population.

Well IMO this is due to the fact that since our inception we have hunted, created wars etc and most of the time until recently women have played a small role in these activities. There's at least 2+ wars a year (many more in the world as a whole) this takes its toll century after century. So what do you all think? Are aliens just a future us? Genderless, asexual beings...

Time will only tell :P
