Excuse me but Creationists have known evolution occurs for at least 200 years. The debate isn't about micro or macro either. If you read talkorigins on the topic macro is evolution at or above the level of species. Linneaus knew that species were not indicative of the Created Kind. He placed it at the level of genus. That alone says Creationists agree with macro as defined at TO. (this is also part of the deception used by evolutionists)
What Creationists debate is the formation of new structures such as arms, legs, spinal cord and brain from an alleged organism that didn't have them.
What is the barrier? Limits exist in life so why is life itself supposed to be an exception? The barriers would be (at least) 1) irreducible complexity; 2) protein structure; and 3) information.
I really wish evolutionists would learn what it is they are debating against. This misrepresentation of the Creationist & IDists position screams of ignorance and does nothing but distract from the debate.
