A. I'm aware that people don't naturally look for the reason in things. Basically, it's kind of like watching a movie you've already seen several times before, you know the plot and major things that will occur but, obviously, the characters in the movie will always respond the same way. No matter how much you analyze the movie, the characters never don't change nor do they have to. Even if they could, it's not nessecary because they already fufill their purpose of entertainment. Something else would be like donating money to a charity. You'll probably never know what happens with the money but you're convinced that it will benefit someone even if ends up being a scam in the end. You don't look for the logic in it first, you just do it or, if you do, you generally don't go as in depth like a conversation like this.
What I meant is that the emotionally driven response that a lot of people have towards any given survival scenario is an evolutionary adaptation because in those high intensity situations where survival depends on quick thinking and fast response times, there isn't time enough to think things out logically, and therefore it's the first "instinctive" and often highly emotional response that takes over. Also, emotions drive people more strongly and more often than reason. This is because emotional responses are, in many instances, the most effective responses in terms of survival.
In short, in certain survival situations, emotions>>logic.
B. In terms of reproduction though, they could still be seen as "unfit."
No. If their genes are still capable of combining with another set of genes to form a viable offspring, they are not "unfit." Darwinian fitness applies to reproduction anyway, so there should be no "in terms of reproduction" regarding this topic as it is ALL about reproduction.
In the far off past, they'd basically drag themselves along the ground but in modern times they could have a wheelchair but the end result of reproduction is still the same.
And if they have wheelchairs, then their offspring will also have wheelchairs, which is comparable to people driving cars to get around, so what is it about this scenario that makes either them or their offspring "unfit"? You could say they are "less fit" than people born with mobility because they need to expend that extra amount of resources to acquire mobility, but there's a certain point where it all blends in with other factors in the same way that other people have lower intellect, or are born into the lower tiers of the socio-economic structure, or simply don't socialize well and may have trouble finding mates.
EDIT: You could be the most athletic and the most intelligent person on the planet, but if you, for whatever reason, don't mate or don't have any offspring, your Darwinian fitness is 0.
Basically, humans have evolved beyond the standard terms for natural selection based on our technology, intellegence, and overall social structure but I still see it a different variation of evolution though.
That's the error in your reasoning, I think. Social evolution isn't any more different than any other aspect of evolution. It is all evolution. It's just social biology. It's game theory. It's genetic warfare. Survival strategy breaks down to numbers and specific scenarios in the end. If the "standard terms" for a scientific theory don't match up with what is observed in nature, it is the theory that is flawed. However, social biology explains how social structure fits right in with evolution and how it is itself a result of natural selection.
Humans haven't "evolved beyond" anything. Humans have simply evolved in a trend that is comparable to social insects. No one is "beyond" evolution. Everyone is a "product" of evolution.
The only end point to evolution that I can see is when a species takes control of the underlying mechanism that allows evolution to occur: genetic mutation. See also, "genetic engineering."
But that's another topic all together.
Also, what's the theory you have about homosexuality? I'd love to hear it.
I thought this thread was destined to be locked by now?
I don't know if social biologists have conducted much investigations into homosexuality in humans and the biological significance of it. I'm sure they have more interesting things to investigate than political non-issues. My speculation goes back to the social insects. Worker ants are sterile; only the queen procreates (most of the time). This set-up is an adaptation that has worked for the success of the species.
Homosexuals are not sterile, but they are less likely to have offspring.
The family unit in human societies is based on cooperation. One aspect of cooperation is providing care for a relative's child when that child's parents are deceased. So, if you and your spouse died, and you have siblings, one of your siblings can provide care for your child. This is more beneficial than not having a family unit, in which case your child would likely die without any parental care. However, if your sibling already has children, the parental care that your sibling and his/her spouse is able to provide for your child has to be divided between all their other children.
But if your sibling is homosexual, has a mate, but no other children, your child would get 100% of the parental care of both foster parents. This would increase the likelihood of your child's survival. Since your child and your sibling share common genes, it would be in the best interest of your sibling to ensure the survival of your child.
This brings to light one of the factors that can place a limit on the benefits of social cooperation, that being intra-societal competition, or competition within the family unit. Most parents favor their own children above all others, and "all others" would even mean the children of deceased relatives whom they must now care for. There is very little such competition within an ant colony (most of the time) because all the workers and soldiers are sterile (again, most of the time), but as they share genetic similarity with the queen and the queen's offspring, it is within their best interest to work for the queen and for the overall good of the collective.
