New light shed on chimp genome:

The key to the distinction between the two species could lie in the functional importance of different levels of gene expression.

OK, we've had our fill of surveys of "junk DNA," let's look at what's functionally important. In these specific details is where the real gold is. It's all good to say that our genome is 98-99% chimp (and so emphasize our common genetic kinship phylogenetically)-but common sense tells us that that 1-2% difference is very crucial indeed (and so realize our uniqueness anatomically).
