The evolutionary tradeoff between becoming a bigger fighter or lover could lead to new species among dung beetle populations. Male beetles may not transform in the blink of an eye, but natural selection seems to have driven rapid evolution in the size of their fighting horns - and their reproductive tools - during a time period of just 50 years in one newly studied case. "As horns get bigger, copulatory organs get smaller, or vice versa," said Armin Moczek, an...
