@genetics --

"A helper kin is not an ideal situation"

"Ideal" situations are not required. This is evolution, after all -- it's a complicated and messy process. "Ideal" situations are few and far between.

In fact, you appear to be placing artificial restrictions on evolution and fitness. We **know** that homosexual behaviors have selective value, because they are so common out in nature. It is not necessary that we know "why" or "how" these behaviors contribute to fitness. We can see that they DO contribute in those situations, even if we don't understand the mechanism (or mechanisms), by their widespread existence.

We do, nonetheless, see the direct benefits to homosexual behaviors in at least some cases. For instance, female-female interactions in bonobos increase group cohesion and decrease aggression. In another example, male-male pairs of black swans are more successful at raising chicks (which, remember, are often biologically related to at least one of the pair) than male-female pairs are. And I'm sure that there are many other cases where the benefits are evident, as well. But again -- we don't need to know the precise mechanisms involved in order to recognize that the benefits exist.
