Explain this:

“Here we present a draft genome sequence of the common chimpanzee (Pan troglodytes). Through comparison with the human genome, we have generated a largely complete catalogue of the genetic differences that have accumulated since the human and chimpanzee species diverged from our common ancestor, constituting approximately thirty-five million single-nucleotide changes, five million insertion/deletion events, and various chromosomal rearrangements. We use this catalogue to explore the magnitude and regional variation of mutational forces shaping these two genomes, and the strength of positive and negative selection acting on their genes. In particular, we find that the patterns of evolution in human and chimpanzee protein-coding genes are highly correlated and dominated by the fixation of neutral and slightly deleterious alleles. We also use the chimpanzee genome as an outgroup to investigate human population genetics and identify signatures of selective sweeps in recent human evolution.”

I explain it simply by the fact that it relies upon the assumption of human-chimpanzee common ancestry to begin with, thereby becoming an example of circular reasoning. See, these differences between the human genome and the chimpanzee genome are assumed to be "accumulated" through divergence from a "common ancestry" - something which is not, actually, immediately apparent from simple observation of the differences. They only "become" evidence for divergence (rather than simple autonomic difference) when one views the evidence through the lens of the philosophical assumptions of evolutionism. There is nothing here which intrinsically "proves" evolution - it merely shows that evolutionists are good at making assumptions and then extrapolating from them.
