mammalian evolution towards colonization of land‚ however in some instances this trend has been reversed; there are three large orders of mammals that have separately re-adapted to marine life‚ the Cetacea (whales‚ dolphins and porpoises)‚ the Pinnipedia (seals‚ sea lions and walruses)‚ and the Sirenia (dugongs‚ sea cows and manatees). This “re-adaptation” is most extreme in the cetaceans which have evolved a totally fish-like form‚ masking their true mammalian ancestry (Coffey‚ 1977). The evolution of

one species exists today—Homo sapiens‚ or human beings. Dr. Alistair Evans and his colleagues based their study off of hominin tooth sizes while trying to figure out what rule governed the evolution and development of teeth in hominins. This study provides a development-based expectation to examine the evolution of the unique proportions of human teeth. While on their journey‚ Dr. Evans and his crew found two types of hominins: the species that we classify as Homo and australopiths. These scientists
