There was nothing in the data available 10 years ago that would lead to your stated conclusions.
‘When we do this alignment, we discover that only 2400 million of the human genome’‘s 3164.7 million ‘‘letters’’ align with the chimpanzee genome - that is, 76% of the human genome. Some scientists have argued that the 24% of the human genome that does not line up with the chimpanzee genome is useless “junk DNA”’
As I noted above, there was never 24% of the human genome that does not line up with the chimpanzee genome; most of that 24% represents DNA we never assembled in the chimp genome, so there was no comparison to be made. Who were the scientists who argued that this was junk DNA?
