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.
1891 The first H. erectus fossils are found in Java. We now think the species appeared at least 2 million years ago in Africa and, again, looked distinctly human. 1924 The discovery of the first Australopithecus remains in South Africa shifts the focus of study to Africa.ut look at its foot and you could think it belonged to our species, which appeared just 200,000 years ago. Its skull, though, makes clear that the brain was less than half the size of ours, and more like that of some species of Homo that lived about 2 million years ago.
