Let say the “common knowledge” aka the “common science” ascribes all major human variations to genes, you know from schizophrenia to homosexuality, etc. In many cases this creates some evolutionary dilemmas, as it becomes difficult to explain why there is such a prevalence of a trait that can put a “host” at a presumed disadvantage. Resolution requires some very heavy lifting. In my previously posted lecture – Robert Sapolsky on Metamagical Schizotypal Thinking, he argues that the reason we still have so many schizophrenics is because they often have a cousin who is a shaman, a rebbe, etc. In other words there is a shadow, highly beneficial for a group trait and this might explain the evolutionary advantage.
But there is a radically different way to explained this. Let take the Toxoplasmosis as an example. Suppose there is a microbial pathogen, an organism that can change the behavior of a mouse (or even a man) to the extent that it not only stops fearing cats but gets attracted to them! Indeed in that Atlantic article that I linked to, the psychiatrist E. Fuller Torrey maintains that the spread of schizophrenia parallels the domestication of cats in Western Europe (urban Paris).
Now Gregory Cochran takes the pathogen hypothesis to the most politically incorrect and logical conclusion, her writes on his blog – Depths of Madness:
“I’ve said it before, but it’s probably time to say it again. The most likely explanation for human homosexuality is that it is caused by some pathogen. It’s too common to be mutational pressure (and we don’t see syndromic versions, as we would in that case), it’s not new, identical twins are usually discordant (~75% of the time), and it’s hell on reproductive fitness. There is no way it is adaptive: the helpful gay uncle notion, group selection, compensating advantage in females, etc: these range from impossible to bloody unlikely. It doesn’t exist in most hunter-gatherers: you have to explain what it is you’re even talking about when you ask them. Presumably with diagrams.
As for Freudian explanations, exotic-becomes-erotic, etc: just reading the social-science literature on the subject is enough to make you wonder if the human brain really does exist to cool the blood.
A fair number of the smarter people interested in the subject agree with me. Not that they think it proven, but they agree that it is the only theory out there that makes any evolutionary sense.”
This of course opens up the hellish possibility that the pathogens, unlike genes, are transmittable.
P.S. A pathogen will interact with a human organism much like a BPA. And we know what these plastic bastards are up to:

Distress Signaling in Plants

Ben-Gurion University study claim that plants communicate with each other through the root system. In an experiment, a selection of plants where exposed to a drought. The stress signal was evidently transmitted through the roots to the neighboring plants, the plants not exposed to the drought. These neighboring plants in response similar to the “drought plants” shut down their “Stoma” or pores on the surface of the leafs. Then the neighboring to the drought plants relayed the stress signal to the further plants that were not immediately bordering the plants exposed to the drought. Here is the paper: PLoS One – Rumor Has It…: Relay Communication of Stress Cues in Plants.
I am trying to think through the implication of this hypothesis, discovery. Can this imply an even more elaborate communication among animals and even people? Is our collective connectivity evolutionary rooted and hard-wired?
