[QUOTE]Originally posted by Baloo: [QB] Not to compare homosexuality to a disease, but the most relevant example I can think of at the moment [i]is[/i] one (bear with me please). If you are of African descent, there is a chance you carry the gene for sickle cell anemia. If you have one gene for the disease, you will not develope it. However, if you inherit the gene from both parents, you will develop sickle cell anemia. Doctors did not understand why a gene that could cause a disease would be so prevalent. They figured that after a few generations, the gene would be eliminated. After much research, scientists discovered something interesting. The people most likely to have the gene for sickle cell anemia lived in areas where malaria was a severe health threat. As it turns out, people with one gene for sickle cell anemia are resistant to malaria. People with the gene are less likely to contract the disease than people without it and if they do get the disease, the symptoms are much less severe. Similarly, gender preference could be governed by a combination of genes that confer a strong survival advantage. After all, we are quite different from our nearest relatives in the animal kingdom with regard to sex. We humans are revved up all the time, at least compared to the rest of the animal kingdom. Since our females don't have an obvious estrus or "heat", it must be necessary to have a number of characteristics that ensure we (collectively, anyhow) mate with the right sex often enough to ensure the reproduction rate outstrips the death rate. Males lack any highly sensitive sensing ability which could clue us in to which female is "in season". Likewise, females lack the knowledge or instinct of when they are most likely to conceive, and are thus not driven to mate when they are fertile. Perhaps the genes (I'm sure it can't be just one gene) for human sexual behavior are so complex that the combination that wires the brain so it knows what to go "Hubba, Hubba!" for can occasionally wind up telling it's host that the correct mate is the same sex. Obviously, there are plenty of us around, and I'll bet the ratio of straight to homosexual persons has been relatively constant throughout history. Of course, since I am not a biologist (and a scientist by method only) I can't say that those are the facts, but I've read enough on the subject to know that real scientists (with letters after their names and [i]everything[/i]) postulate much the same theory. No-one's sure whether it's correct yet, but it seems to be the way to bet right now. --Baloo [/QB][/QUOTE]
