Homosexuality is not determined by genes. The theory is that homosexuality is associated with a combination of gene sequences (not individual genes) with gestational hormones.
Gene sequences can occur and recur regardless of whether certain individual genes become rare or even extinct.
If homosexuality is genetic, born to parents that aren't, that would mean the gene is recessive. Suppose H is heterosexual and h is homosexual. If two Hh's marry and the kid gets h from both parents, s/he is then gay.
This depends on who you are asking. Some people will say no (because they will not have any children of their own). These people usually do not like homosexuals. Some people will say yes (they will not pass on their genes to the next generation).
It depends on who you ask and where you are asking. The world is in a state of rapid evolution on the subject.

Cultural evolution is the phenomenon whereby cultural ideas, notions, views, etc. propagate throughout populations, like alleles propagate throughout population gene pools in biological evolution.Some propose that the way these ideas propagate throughout populations is similar to the ways of biological evolution, in that cultural ideas (or memes) are subject to a kind of cultural selection, that determines how fast they spread, and to what degree.
a game where your creature changes/evolves throughout the game, famous evolution games are, evolution the game of life, spore, dark-spore(coming soon) and also two free flash games, monster evolution and bug evolution (but the last two defiantly aren't as good).
The relationship among an organism's environment, adaptations and evolution is that the environment will alter, so the organism has to adapt to the new environment. Throughout the years this has created evolution seen in fossils and history books
Yes. There is no set rate for evolution; the speed by which populations diverge behaviourally, morphologically and genetically is determined entirely by circumstance. Even different genes in the same population gene pool can have different rates of evolution.
Some would like to say that there is no such thing as evolution, some would argue for the idea. I suggest that the whole concept of evolution is a relative one, in which we as humans have determined what it is or isn't, as we do with most ideas. So what evolution is will be different for each person. Hence there is no need to say there is or is no evolution, but rather, this is my idea of it. Still there is a problem I feel, with the question itself. It asks about the "cycle" of evolution. That assumption may not be shared even by those who agree that we are an evolving species. Whether it be from a biological evolution or a spiritual one, does the process have to be cyclic? Could it be linear, or multi-dimensional? Could it be finite or infinite, even if it is determined to be cyclic? Thus the questioner needs to rephrase his or her question. I think when doing this, the answer will be found in the question! - Parinda
Mckinnels' hypothesis of homosexuality being an evolution of man is quite a perculiar and distinct theory(Also disturbing). This theory includes ideas so radical that it is almost unbelieveable however, the theory is quite straight forward if understood correctly. The theory was that "gayness"(see Homosexuality.) is an evolution of man to help with the growing problem of population growth. Mckinnel stated that whenever there was a problem in the past mammals have evolved to deal with it. E.g African lung fish moving onto land. So he proclaimed that humans evolved to help humanity deal with population. If humans infact all becanme "gay" then the population would drop dramatically and hopefully save the human race from population overload. The quote "people are born gay" obviously proves the fact that its an evolution/mistake in genetics. Mckinnel hoped that his theory would be realised and took on board by younger generations.

The point of Evolution is that it doesn't start or stop at any given point. It's a natural process that happens throughout life. Evolution is caused by triggers in genes. Different animals have different triggers. These triggers can be caused by different things, but most commenly a change in habitat.
