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.
An important part of our family tree, Australopithecus, literally meaning 'southern ape, is now extinct, but the genus was made of five distinct species: A. afarensus, A. africanus, A. anamensis, A. garhi, and A. sediba. With their various characteristics, they each contributed to the evolution of Homo sapiens.ifferent aspects of its teeth point to similarities to other Australopithecines as well as to Homo species. Its pelvis and lower chest resemble those of Homo, while other traits resemble those of Australopithecus. A. sediba is therefore a good candidate for being a direct ancestor of the genus Homo.
