Article: The Face that changes the Human Story: But How? Scientists have discovered a new species of the human ancestor in a South African cave that adds to the family tree. The discovery is primitive in certain aspects like the face Trey Nielsen World Baseball Classic Jersey , skull, and the teeth that show adequate modern features to justify the creature in the human being linearity. An artist called Gurche spent more than 700 hours to reconstruct the head from the gathered bone scans and used bear fur for the hair (Shreeve, 2015). The bones found deep within a South African cave are a representation of a new species of human ancestor. The scientists called it Homo Naledi, and it appears primitive with a tiny brain, and apelike shoulders for climbing and in other ways like the modern humans. The questions of when it lived Tommy Layne World Baseball Classic Jersey , where it fits in the family tree, and how its bones got into the deepest hidden section of the cave were some of the issues to find out. It appears that the story is one of the greatest discoveries of the past half-century and has a significant meaning to understanding the evolution of man. The discovery In 2013, two recreational cavers entered a cave called Rising Star which is 30 miles northwest of Johannesburg. The cave is popular for cavers since the 1960s (Shreeve, 2015). The first half of the 20th century saw the region of South Africa produce many fossils of the early ancestors that later became the Cradle of Humankind. The two cavers knew that a scientist in Johannesburg was in need of bones. Tucker and Hunter cruised their way through a constriction called Supermans鈥機rawl that people can only fit through by holding one arm tightly against the body and stretching the other above the head. They crossed a large chamber and climbed a jagged wall of rock called the Dragon鈥檚 Back. Hunter removed his video camera, and Tucker eased himself into a fissure in the floor of the cave. His foot felt a finger of rock and another beneath it and empty space. After dropping down Tiago da Silva World Baseball Classic Jersey , he entered a narrow, vertical chute and called his friend to follow him. Their body size enables them to fit in the chute which is the most astonishing human fossil discovery in the recent past. Tucker and Hunter moved deep 40 feet down the narrow chute in the Rising Star cave and dropped into another pretty chamber having white flowstones in one corner. The passageway directed them to a larger cavity, 30 feet long and a few feet wide having its walls and ceiling with the bewilderment of calcite gnarls and flowstone fingers (Shreeve, 2015). At the floor, there were bones everywhere. The cavers thought that they were modern since they were not heavy like other fossils nor were they engraved in stone. They lied on the surface Sebastian Poma World Baseball Classic Jersey , and they noticed a piece of a lower jaw with teeth intact that looked human. Lee Berger is the paleoanthropologist who had requested the cavers to look for fossils. He wanted to find fossils that could shed light on the existing mystery in human evolution which is the origin of our genus, Homo. There are apelike australopithecines there were known as Australopithecus afarensis and the famous representative, Lucy, which is a skeleton found in Ethiopia in 1974 (Shreeve, 2015). Next to it is Homo erectus Sam Gaviglio World Baseball Classic Jersey , which was a species known to be tool wielding, fire-making and with a big brain and body proportions like ours. A million year gap is said to be the transition period of the bipedal animal to a nascent human being adaptable to the environment and with a functional mind. The fossil records appear frustrating and ambiguous due to the many questions of the evolution phases. Homo habilis, handyman, as called by Leakey and his colleagues believed was responsible for the stone tools found at Olduvai Gorge in Tanzania. In 1970s, a team led by Louis son Richard found more H. habilis specimens in Kenya (Shreeve Rob Segedin World Baseball Classic Jersey , 2015). All along, the species offer an unsatisfying basis for the human family tree. According to Berger, Homo habilis was a very primitive creature that could not fit in human genus. He argued that South Africa was the best location to search for the real earliest Homo and not East Africa.
