One of the hardest things to get from a true believer is an account of what evolution actually is, and how evolution occurs.

Everything that I observe in nature tells me that evolution does not occur. Take three examples of birds that were transplanted to the western hemisphere for sporting purposes: ringneck pheasants, gray partridges and chukar partridges. All have been successful pioneers on this new (to their species) continent, but only within the realm of their original habitat. They all look exactly like their ancestors, and none have "evolved" the ability to expand their range into apparently friendly habitats that border their range.

Why have these species not been able to adapt and expand into new range? What prevents their adaptation?

An open mind is a rare and precious thing. If you agree with me, you are open-minded.
