Document Summary
Revolutionary because it is one of the oldest things anyone had discovered. Australopithecus afarensis (same genus names originally used for south african forms) Showed body plan (most of finds in this time were just bits and pieces of squeleton) Long powerful arms in relation to legs (hip, knees, ankles changed first) Feet extremely ape like (lucy= a mosaic of features. She resembles modern apes and modern humans anatomy. ) Laetoli: place where about 3mya, there was a volcano eruption (the surface was coated with volcanic ash. ) Before the ash cooled completely, a number of animals, including bipedal humans, walked on it, leaving footprints. The humans had similar feet to ours, and had bipedal walking. Their big toes completely aligned with the rest of the toes (just like us) Older than lucy, but in the same area, different genus name. Aramis is the area where they found them. They are more like the common ancestor of chimps/gorillas.
