Orangutan 48 1980: Banding patterns of humans and chimpanzees match. 1961: Gorilla and orangutan chromosome numbers are 48. 1982: Telomeres in middle of human chromosome 2. 1975: Detailed analysis confirms common ancestry. 1960: Chimpanzee chromosome number is 48. 1958: Human chromosome number is 46. Evolution is TestableHuman & Ape Chromosome Numbers Hypothesis: Human chromosome 2 resulted from the fusion of two chromosomes present in the common ancestor of humans and the other great apes.
