The new mini-mockumentary attacking evolution by Ray Comfort has gotten a lot of promotion on this site and I thought I’d post one of my responses to the claim that no scientist in the world can give an example of one “kind” of life changing into another “kind”, and how this is such a terrible proof against evolution. I said to someone asking for such an example:
It’s a trick question. “Kind” has no biological or biblical definition and all forms of life are in some sense the same “kind”, because all “kinds” of life fit within parent or daughter groups which unify all living things – this is why universal common ancestry is so widely accepted. For instance you might say cats and dogs are different “kinds” of animals, because one is a feline (along with lions, panthers etc) and the other is a canine (along with wolves, coyotes, foxes, dingoes etc), but canines and felines are all mammals, they are all the same “kind” of animal, as opposed to reptiles, amphibians, dinosaurs, birds, etc. But then all those groups are all animals as opposed to say plants. But then plants and animals are all eukaryotes, because they have nucleic cells and various other cellular and genetic traits, and so on and so forth.
If by “kind” they mean species we’ve observed that, google “observed instances of speciation” or check out ring species (which these big creationist websites have no response to whatsoever) for examples of species splitting off to form new but similar species. In reality evolution isn’t a dog turning into a worm or whatever nonsense, it’s more like one feline species branching into two varieties of felines. Over vast stretches of time and slow, geological changes in environments the differences get more significant, but we only know this by fossil and genetic evidence. This is similar to the way we all observe the english language changing in our lifetime but we only know the extent to how much it’s changed over hundreds or thousands of years by looking at documents from different centuries. But no one would suggest that because we don’t observe in a year 500 years of change that it didn’t happen. That in shakespeare’s day they spoke the same english we do.
But I could do the same thing they’re doing and demand you show me in person an example of one “kind” of language changing into another “kind” of language and mocking or editing any answer you gave to make it sound ridiculous.
