For creationists who claim that microevolution and macroevolution are two different things, here is a simple challenge:

Show us a single genetic difference between the human and chimp genome that could not have been produced by known microevolutionary processes in either the chimp or human lineages.

Just for clarity, I am defining a microevolutionary change as a single mutational event (e.g. base substitution, insertion, deletion, transposon insertion, retroviral insertion, or genetic recombination) that is passed on to descendants.

As an example, here is a comparison of portion of the human HNF1 homeobox A gene and the homologous chimp gene:

Query 121 GGCCCTACCTCCTGGCTGGAGAAGGCCCCCTGGACAAGGGGGAGTCCTGCGGCGGCGGTC 180
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Sbjct 1220 GGCCCTACCTCCTGGCTGGAGAAGGCCCCCTGGACAAGGGGGAGTCCTGCGGCGGCGGTC 1279

The human sequence is on top, and the chimp sequence is on the bottom. The "|" symbols indicate where the two sequences are the same. As you can see, there are two base substitutions in the middle row.

Can any creationist give us a single reason why two microevolutionary events could not produce those two base differences? Can creationists point to any different in the chimp and human genomes that could not be produced microevolution?

To admin: Would prefer placement in the Biological Evolution forum.
