Intelligent (maybe), but far from perfect

One of the inconsistencies brought up by an early post is the diversity (imperfections and all) that exists in humans today and the belief that we all come from A&E 6,000+ years ago. It is my understanding that ID accepts microevolution but not macroevolution. If we all started out perfect with A&E, then how did we become so different in such a short time? If one accepts microevolution, DNA mutation leading to minor changes, then one most accept that the rate of this mutation has been well documented for many speicies. The point is that there are too many mutations in the human genome for all of this to have happened in 6000 years.

According to this from the Discovery Institute, IDers are ok with microevolution but not macroevolution. I'm not an ID expert by any means, I've just had discussions with ID beleivers.http://www.discovery.org/scripts/viewDB/filesDB-download.phpSorry, I'm new here, but what does YEC refer to?
