Crow believes that the same genetic changes that allowed the development of language by creating imbalance in the brain also created the potential for schizophrenia. The causal link between exposure to high levels of testosterone in the womb and subsequent left-handedness has not been conclusively proven, and indeed more recent research strongly suggests a genetic link to left-handedness being far more likely.

Tricky business, eh? RESEARCH GUIDE. Research by Amar Klar indicates that about 45% of left-handers have anti-clockwise hair whorls, compared to only about 8% of right-handers, suggesting a possible genetic link between the two phenomena, but it is by no means a simple link.
