Document Summary
When and where did the first humans appear (con"t) Lucy australopithecus afarensis; discovered by donald johanson. In 2005, at the site of gona in ethiopia cut marks on animal bones associated with australopithecines that date to 2. 5-2. 6 mya: indicate that these early hominids used stone tools. In 2010 butchered animal bones dating to 3. 4 mya near some australopithecines were found: probably were consuming a portion of meat in their diet, scavengers; meat eaters. Mosaic evolution: characteristic of hominid history, evolutionary changes where certain body parts evolve more quickly than others. Australopithecines can be divided into two different categories. Robust: a. boisei, a. robustus, a. aethiopicus (sometimes called p. aethiopicus) Robust larger bone structure, pronounced sagittal crest and zygomatic arches: cheek bones are zygomatic arches, much larger jaw and dentition. Features on skull adapted for chewing tough foods. Enormous face and jaw muscles (gorillas have a big sagittal crest)
