Ron Reagan, the son of former President Ronald Reagan, slammed Republican presidential candidates Rick Perry and Michele Bachmann on Monday for not accepting the theory of evolution and evidence of climate change.

"Neither seem to accept Charles Darwin's idea that species, including the human species, evolve over time," he said, appearing on MSNBC. "Instead, they pretend there is a scientific controversy involving evolution where none exists."

Reagan noted that neither candidate believed human activity was contributing to climate change, mocking Perry's suggestion that all evidence of such climate change was a hoax.

"Any rational person would consider such wild, unsupported claims an embarrassment, and the folks who made them unfit for high office, yet here they are," he said. "President and crazy are not two words we want connected."
