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.
The first A. afarensis knee joint was discovered in November 1973 by Donald Johanson as part of a team involving Maurice Taieb, Yves Coppens, and Tim White in the Middle Awash of Ethiopia 's Afar Depression.y the time it was found, it was the first complete skull of A. afarensis. The rarity of relatively complete craniofacial remains in the A. afarensis samples before the discovery of AL 444-2 seriously hampered prior meaningful analysis of those samples' evolutionary significance.
