Look what the cat dragged in: do parasites contribute to human cultural diversity?
Kevin D. Lafferty
2005, Behavioural Processes (68) 279-282
If human culture emerges from the modal personality of a population, can global variation in parasitism that affects personality lead to cultural diversity among nations? The answer could help explain why people seem to vary so much from one land to another. Thomas et al. (2005) review how parasites manipulate behaviour,...
