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…” 2005

3 Evolution is Testable Human & 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. 1958 Human chromosome number is 46. 1960 Chimpanzee chromosome number is 48. 1961 Gorilla and orangutan chromosome numbers are 48. 1975 Detailed analysis confirms common ancestry. 1980 Banding patterns of humans and chimpanzees match. 1982 Telomeres in the middle of human chromosome 2. centromere telomeres 48Orangutan 48Gorilla 48Chimpanzee 46Human 1958: Human chromosome number is 46. 1960: Chimpanzee chromosome number is 48. 1961: Gorilla and orangutan chromosome numbers are 48. 1975: Detailed analysis confirms common ancestry. 1980: Banding patterns of humans and chimpanzees match. 1982: Telomeres in middle of human chromosome 2.
