Though the study isn't able to conclude that (a human gay gene), the dude, Hayes, seems quite worried that that IS possible. However, like someone mentioned below, there IS plenty of evidence of gay behavior in nature... and this is a relatively new pesticide (or is it? Ya know, I don't know that...). That being said, it certainly looks possible that the chemical can effect male humans in a similar manner (and may already be doing so).

Is it the cause of homosexuality in humans? Probably not, but it certainly can be contributing to the numbers now (more so than nature).

In the Youtube video I linked he talks about the offspring of rats, I think, that had been exposed to atrazine. A few generations away, and the side effects were not pretty.

Crazy stuff. 😲
