Research has shown that women who are infected with the parasite tend to be more warm, outgoing and attentive to others, while infected men tend to be less intelligent and probably a bit boring. But both men and women who are infected are more prone to feeling guilty and insecure.
Other researchers have linked the parasite to schizophrenia. In an adult, the symptoms are like a mild form of flu, but it can be much more serious in an infant or fetus. Oxford University researchers believe high levels of the parasite leads to hyperactivity and lower IQ in children....
Lafferty argues in a research paper published Aug. 2 in the Proceedings of the Royal Society, Biology, that aggregate personality types, or what cultures tend to be like, fit neatly with the effects that the parasite causes on an individual level.
Is a cat parasite creating different owners that make human societies better for our lords and masters? He now says that:
Cat lovers need not get rid of their cats. The chances are not great that a modern cat, kept on a diet of safe cat food and not left to feed off rats, will transmit the parasite to humans. It's possible, but not likely, Lafferty says.
But is a parasite making him say that? It isn't clear from this report what all the changes are in males with the parasite. Male rats become more adventuresome and less frightened of cats making them easy prey. Was this cat biological warfare against rats that is now being modified for humans?
