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.
Best Answer: There is one thing you must understand about the so-called cavemen. They were nothing like the guys you see in the Geico commercials. The species known as AUSTRALOPITHECUS AFARENSIS is an extinct hominid which lived between 3.9 and 2.9 million years ago (if you want an exact year, put BC after the 3.9 million) and was the first hominid--or man-like being--to walk on both feet, and not live in trees.
