Tom Rees, over at Epiphenom, draws our attention to some fascinating research:
Polygamy is pretty popular. Most pre-industrial societies were polygamous in some way, and there are increasing pressures in the west for polygamy to be legalised. After all, it’s surely just a matter of personal freedom of expression. If homosexuality and other forms of sexual expression are legal, then why not polygamy. Polygamy never hurt anyone, right?
Well flat wrong, actually, if the evidence presented by Joe Heinrich, at the University of British Columbia, is anything to go by.
