I'm not saying it is "useless junk", just that the coding regions are almost identical. That near identity speaks volumes about the relationship between us and chimps.
Has Chimp DNA even been completely sequenced yet? If not, how can one say with certainty that the coding regions are almost identical? One would have to resort to statistical analysis, which in this case is fraught with difficulties.
That near identity speaks volumes about the relationship between us and chimps.
The 'volumes' in that 4% contain probably around 120 million base pairs, equivalent to approximately 12 million words, or about 40 large volumes of information. 'Near identity' and 'the relationship between us and chimps' is in the eye of the beholder.
Cordially,
