Man, gorilla, and chimpanzee likely shared an ancestor in whom the fine genetic organization of chromosomes was similar to that of present man. A comparative analysis of high-resolution chromosomes from orangutan, gorilla, chimpanzee, and man suggests that 18 or 23 pairs of chromosomes of modern man are virtually identical to those of our "common hominoid ancestor", with the remaining pairs slightly different. From this lineage, gorilla separated fist, and three major chromosomal rearrangements presumably occurred in a progenitor of chimpanzee and man before the final divergence of these tow species. A precursor of the hominoid ancestor and orangutan is also assumed.
