Australopithecus

he concluded that this knee belonged to an individual who was bipedal; a species that walks on two legs. A year after his first finding, Johanson went back to Ethiopia with his own expedition team to find what will later be called, Lucy, the Australopithecus Afarensis. Lucy turned out to be one of the oldest human ancestor at the time. At first Lucy’s skeleton looked like an ape’s…

Dr. Donald Johanson discovery of Australopithecus Afarensis in Hadar, Ethiopia and Mary Leakey’s discovery of the Laetoli footprints in Olduvai Gorge, Ethiopia proved beyond any plausible doubt that human species had evolved and Lucy was one of the species that bridged this gap between pre-humans…

Mary Anning was considered to be the first female paleontologist and the greatest fossil finder. She overcame a lack of formal education to emerge as one of the foremost authorities on fossils. When she was twelve year old, she found the skeleton of one of the first Ichthyosaurus, a giant marine reptile that lived in the early time of Jurassic period in Asia and Europe. She discovered more Ichthyosaurus fossils and also many other important discoveries as an amateur fossil collector in the…

features that are associated with arborealism (Australopithecus, 2000). Africanus was next it was classified as having combined primitive characteristics with derived features associated with the human pad-to-side precision pinch and handling grips (Australopithecus, 2000). Anamensis lastly is a proximal hand phalanx that is curved and has strong ridges for the attachment of the flexor sheath (Leakey et al 1998). Both features are present in Australopithecus a farensis and are considered…

known hominid, Australopithecus Afarensis, also known as "Lucy", had a difference in their appearance compared to modern humans. Lucy's height was about three feet tall, almost the average height of a female (three foot five). I tried researching Lucy's weight and had little success, however, the average weight of a female was about 64 pounds. Also, the average height for the males was about four feet eleven inches and the average weight of a male was 92 pounds. The Australopithecus Afarensis…

Charles Darwin is a scientist that came up with the theory of natural selection to explain variation and evolution. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype (Zimmer&Emlen, 2013). This means that in an environment where the condition is constantly changing, species that stay in that environment and use it as their habitat adapt to the changes of the environment to survive the changes and their off springs are also able to…

proved their theory by digging up fossils of these ancestors. The differences between the hominids: Australopithecus afarensis This species of hominids was discovered during the 1970s. The fossils found was believed to have been dated back to 3 million – 4 million years ago. The Australopithecus Afarensis is thought to be the oldest hominids species to have ever lived. Australopithecus Afarensis…

ramidus was first reported. Ardi's foot bones appeared to have a divergent large toe with a rigid foot. Her pelvis showed she had tree climbing and bipedal abilities. Australopithecus afarensis       Australopithecus afarensis was one of the longest-lived and well known early human species. Australopithecus afarensis lived among the Eastern Africa in Ethiopia, Kenya, Tanzania.…

we different from other species. Science brings us to new knowledge of how humans evolved in this world and the transition of apes to humans. The Human family tree starts from the Ardipithecus groups about 6 million years ago, the next one is Australopithecus group is about 4 million ago, the third one is paratroops group is about 3 million years ago and the last one is the homo groups is about 1 million years ago. Ardipithecus kaddaba was discovered in Ethiopia in 1997 by a…

Hominids are humans and their bipedal relatives; hominid evolution has taken many years of looking for fossils to discover the modern humans past. There has been many scientific research and development done in order to find more about the modern human’s ancestors. Hominid evolution is a lengthy process of change occurring for millions of years. Modern humans, also known as Homo sapiens, are the only surviving species of the genus Homo. Three important ancestors that share close relationships…
