OK, here is a fun puzzel with 3 senarios.
At the begining of times of Humans here on earth:
1- All humans both Males and females are "Heterosexuals"
2- Humans are equaly split between "Heterosexuals" and "Homosexuals"
3- All humans both Males and females are "Homosexuals"
Q: what the result of impact of each scenario on humanity?
1-Homosexuality will emerge.
2-Heterosexuals will become more frequent than homosexuals in the overall population, but homosexuality will not disappear.
3-Homosexuals will have heterosexual relationships to continue breeding until such a time that heterosexuality re-emerges, or the species will die out.
I have a better one, though.
4-Approximately 10-20% of humans are homosexual or bisexual, the other 80-90% are heterosexual.
Since #4 is much closer to reality than any of yours, I'll go with that one. So far, it's working out great. We've still got more than six billion humans around and we're still growing faster than we should be.
There's a lot of research on this topic. Please educate yourself. Please.
