Imagine spending 40 years of your life promoting Darwinian evolution with Galapagos finches, only to find out on Darwin Day that the birds hybridize and cross-breed.
There's something magical about believing in evolutionary anthropology: a sense of numinous awe at how much they don't know but believe might be possible.
It would seem Darwinism has been falsified by evidence for organisms that never evolved for "two billion years" but some call this a vindication for Darwin.
