Heart disease genes may boost reproductive success

Associated Press

Coronary heart disease has likely plagued and killed humans for thousands of years and is still one of the leading causes of death worldwide in the 21st century. Big question: why hasn't evolution weeded out the genes that cause this common, deadly condition in the human heart system?

It seems we might need those genes for something else that the human species considers an even more urgent, primal need – raising lots of children. Researchers found that the same genetic variations that contribute to plaque buildup in arteries, which cause coronary heart disease, also contribute to greater male and female reproductive success.
