"We usually think of natural selection as acting directly on the genes that influence a specific trait," said Leonid Kruglyak, one of the co-authors on the paper and the William R. Harman '63 and Mary-Love Harman Professor in Genomics at Princeton. "This paper shows that there is an indirect evolutionary force that can override this direct effect -- selection acting on neighboring genes that just happen to travel together on a chromosome with the genes that influence the trait."
An interesting article on pros and cons of capitalism. While capitalism offers financial profit for anyone willing to work hard, capitalism also allows for selfishness and wayward personal motivation. An interesting moral view.
