2. Does The Evidence Support Evolution?
“More than a century ago, Darwin and Huxley posited that humans share recent common ancestors with the African great apes. Modern molecular studies have spectacularly confirmed this prediction…”

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.
