I believe the Greeks had an appropriate word for this: Hubris.
I wish to see an experiment, without tampering with the genes, where the initial and future conditions of an environment are set, and a prediction is made that is verified--especially with something like a fluke becoming a new species--according to what was predicted. Of course, one can look to variations that cannot be controlled in the environment, and therefore perhaps not a 100% perfect result can be had.
Until that happens, the know-it-alls like the fellow quoted above can stuff it.
And as far as 'we have already verified this theory', stating that one theory is valid because another theory supports it ( thereby fufilling predictions of the first theory ) is dishonest legerdermain.
OK. Take two herds of horses. Keep one on the plains. Put the other one in an environment where the land rises one inch per centry. 1 foot in 1200 years, 1000 feet in 1.2 million years. Let's let it go on for say, 5 million years.
I'm sure the actual biologists here can do better, but I'd predict that the 'horses' on the higher, more mountainous area will resemble (at least in behavior, I don't know about appearence) present-day donkeys or burros more than the original horses. (eg, they'd be more sure-footed than their ancestors)
When you've invented time travel, let's conduct the experiment. Until then, we have to work with what's available, namely fossils and DNA.
Can some creationist/IDer give me pointers on how to set up an experiment where we can observe 'special creation'?
