I've often wondered how I came to be the way I am... or better yet, what about that guy over there!? Phew! Are we changing for the better or the worse? According to some scientists our future is narrowing.
Through diligent work and with the help of a few thousand rats that volunteered to have their genes spliced, scientists have determined that if my ancestors had enjoyed a larger choice of mates I would now be far healthier. In their words, "They (researchers from the universities of Bath, Edinburgh and Sussex) believe that if our ancestors had benefited from the vast choice of mates available to other species such as mice and rats, there would have been fewer of the mutations in our DNA that can trigger illness."
I not sure if I am happy for all those healthy rats and mice, or saddened at my genetic propensity to illness... Maybe just a bit of each.
