The species is also known for the footprints at Laetoli, Tanzania (3.6mya). Lucy was only about 110 centimetres tall but was a fully grown adult when she died. These changes have resulted in dramatic increase in brain size and the reorganisation of the brain in which some parts, such as those involved in learning, have developed more than others, such as smell and vision. like all human ancestors, the spinal cord emerged from the central part of the base of the skull rather than from the back.

Part way along the trail the individuals pause and turn to the left before continuing. Its age indicates that Australopithecus anamensis coexisted with Australopithecus afarensis, a species that anthropologists thought lived later on. In 2010, fossil bones bearing cut marks were found in Dikika in Ethiopia, dating to about 3.4 million years old. Sticks and stones picked up unaltered from the ground were probably the only implements used by the great apes and earliest human ancestors. Key Difference – Paranthropus vs Australopithecus Hominidae is a taxonomic family of primates whose members are known as great apes or hominids.This taxonomic group included the ancient extinct hominins such as Paranthropus, Australopithecus and Homo group including modern man.The Paranthropus is described as a genus of extinct hominins. The most celebrated Australopithecus, Lucy, discovered in 1974, was a member of this species. The names Praeanthropus africanus and Praeanthropus afarensis have been suggested as alternatives by researchers who believe this species does not belong in the genus Australopithecus. Although no hominin remains were found at the site, the discoverers believe A. afarensis was responsible for the cut marks as no other hominin species dating to this period have been found in this region. The fossil skull was from a three-year-old bipedal primate that he named Australopithecus africanus. In the past, our ancestors relied on genetic adaptations for survival. They show that the heel was the first part of the foot to strike the ground. The book is the most in-depth account of the fossil skull anatomy and evolutionary significance of the 3.6-3.0 million year old early human species Australopithecus afarensis .
