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.

That was the Taung Child, the fossilised skull of a young child who lived about 2.8 million years ago in Taung, South Africa. The Taung Child was discovered in 1924 and was studied by anatomist Raymond Dart.
