mm-hmm, what kind of powerful experiments did darwin do to overturn the very old theory of his day??
seems like evolution was impossible to do experiments on..
was going to submit an essay on this article but had no idea how long it was already
He didn't overturn the old theory so much as he described the mechanism of natural selection. Evolutionary theory had been around for a while.
Also most of the evidence for evolutionary biology is observational, not experimental. People don't live long enough for the kinds of experiments that would be fun to do with evolution.
