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 hyoid bone of the juvenile Australopithecus afarensis fossil suggests that this species probably couldn t: speak like a human. The large brain is often considered a hallmark of modern humans and our hominid ancestors; however, it is not one of the characteristics thought to be obligate when discussing hominids.e is unable to remember the species name but knows that it lacked the specialized teeth seen in living apes, had elongated toes, an opposable big toe, and was part of a multidisciplinary study that reconstructed the early hominids habitat. The fossil he is.
