I was wrong in the detail. It's closer to 98% than 99%. (Sibley et al.,
1990, Journal of Molecular Evolution 30: 202-236) using DNA-DNA
hybridization methods, which measure the similarity at the DNA sequence
level of all single copy sequences between two genomes found that humans
differed from chimpanzees by 1.61% (on average, 161 substitutions are found
along any string of 10,000 nucleotide sites). Gorillas differ from humans by
1.72%, Oranutans by 3.39%, Gibbons by 5.05%, Old World monkeys by 7.43%, and
the next similar animal is around 10% (New World monkeys).

DNA hybridization does not require sequencing.

You got me there!
