Re: X-seed 4000
Savage! That would be seriously awesome. But how could it get planning permission? Won't the shadow be a problem?

Re: How can gayness have a genetic basis?
For sure. Really my whole interest in this concerns the possible genetic basis at root of the phenomenon. The only reason I've used the term 'gayness' so broadly is that unless we want to speculate...

Re: Random Question About Genetic Traits
Do yourself a favour and never mention your profession in discussion if it's just something to lend a whiff of authority to your unsubstantiated claims. What you end up saying is that at least your...

Re: How can gayness have a genetic basis?
As I said in the OP, I find this unsatisfying as an explanation. I can see how an excess of hormones/whatever might make a male less likely to reproduce - I don't see how it could result in gayness....

OK slow down. Please don't put words in my mouth.

I have not said that gayness is unfit - I have said I do not see how it can be.
