The gene that is always expressed and will produces a trait is a genetic statistic. This statistic is what is created when the gene is dominant.
Evolutionary Tree Information: This species may be a direct descendant of Au. anamensis and may be ancestral to later species of Paranthropus, Australopithecus, and Homo. AL 288-1. âLucyâ (AL 288-1) is an adult female, 3.2 million-year-old A. afarensis skeleton found at Hadar, Ethiopia.Because she could walk upright on the ground and climb trees, she and other members of her species were able to use resources from woodlands, grasslands, and other diverse environments.he Laetoli footprints were most likely made by Australopithecus afarensis, an early human whose fossils were found in the same sediment layer. The entire footprint trail is almost 27 m (88 ft) long and includes impressions of about 70 early human footprints.
From paleontological and archaeological evidence, the Australopithecus genus apparently evolved in eastern Africa around 4 million years ago before spreading throughout the continent and eventually becoming extinct somewhat after 2 million years ago.or some hominid species of this time, such as A. robustus and A. boisei, some debate exists whether they constitute members of the same genus. If so, they would be considered 'robust australopiths', while the others would be 'gracile australopiths'.
