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.
ONE of our closest long-lost relatives may never have existed. The fossils of Australopithecus sediba, which promised to rewrite the story of human evolution, may actually be the remains of two species jumbled together. The first fossils of A. sediba were found at Malapa, South Africa, in 2008.At 2 million years old, they show a mix of features, some similar to the ape-like australopithecines, others more like our genus, Homo.ith anatomy in flux, it is possible that one A. sediba had an Australopithecus-like spine and Homo-like jaw, while another had a Homo-like spine and Australopithecus-like jaw. There are other features of the A. sediba vertebrae that might explain the differences Been found.
