Homosexuality and evolution

Post Reply New Topic

In models 3 and 5, where Antrax assumes a constant population, everyone has the same probability of death. There is no law of statistics or biology that states a population can't die faster than the replacement rate. If you want to introduce that assumption into your argument, you have to justify it.

I responded to you saying that there has to be competition between species. What does this have to do with mortality rates being greater than birth rates for some populations within a species?

This is the definition of not being significant enough of a drag on reproductive fitness. Say completely arbitrarily that a population was increasing at 5% a year, but then there's a mutation that caused some of them to only increase at 2.5% a year. They'd still be increasing in population, but the mutated gene would be halving their growth rate. I don't see how that would be bred out unless there was some kind of direct competition where numbers was an advantage. It's not evolution exactly but it is a competition: the North won the Civil War because they had like four times as many people (and they were better armed, etc.).

a lot of gay boys have dominant mother and loser father .

The definitions of fitness I have seen were concerned with the proportion of an allele in the next generation, not the absolute number.


Resources are finite, so there is a limit to population size. Infinite growth is impossible outside of mathematical models. There are many ways of competing: attracting better or more mates, being better at finding the resources needed for survival and reproduction, being better at hiding or running from predators, having more efficient metabolism, having better resource extraction skills. Many of them have nothing to do with either other species or with killing within a species.


So where is the other species that you said is necessary?


Sounds very Freudian. Do you have a reference?

So do a lot of straight boys too.

Whats your point?

If your point is that that environment produces gay men -then- why hasn't there been a gigantic outbreak of male homosexuality in America's Black ghettos iwhere female headed households are close to being the norm?

A lot of gay boys drank homogenized milk when they were kids. A lot of straight boys did, too.

What next, "Refrigerator Mothers"?

Well...

You keep your homogenized milk IN … a refrigerator.

And that's why ...we have kids who end up on milk cartons!

Right alongside the runaway trains.

Across similarly long time scales everything else evolves and all the niches change. Things in nature aren't in evolutionary equilibrium with each other with respect to their "niche," they're constantly chasing shifting conditions that change what's optimal. You're thinking with a convergence mindset about a system that never converges.
