For all of you with an attractive cousin – I have some good news.
According to new research by Murdoch University professor Alan Bittles, having sex with your cousin does not lead to any negative health consequences:
“Our findings over years of research have shown that the health risks associated with consanguineous marriage have been exaggerated, largely due to flawed research design, with a failure to allow for non-genetic factors that can adversely influence health outcomes,” he said.
Bittles claims more than 1.1 billion people or 10% of the world’s population are either married to a close relative or the offspring of such a marriage. He believes that there could be some genetic advantages to same-blood offspring:
“mainly the advantages are social and economic in nature, with the strengthening of family ties, and the maintenance of family goods, including land-holdings,” he said.
Bittles denies researching this topic because he has a sexy cousin and insists that the “central aim in (his) work is the prevention of genetic disease through a better understanding and appreciation of how genes are transmitted within families and communities.”
