Australopithecus afarensis is one of the longest lived and as well-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals. Found between 3.85 and 2.95 million years ago in Eastern Africa, this species survived for more than 900,000 years, which is over four times as long as our own species has been around. Australopithecus afarensis is very similar aspect of both modern chimpanzee and human.
The first and most important is that physical characteristics of modern chimpanzees has same and different point from Australopithecus afarensis. According to “Exploring Biological Anthropology” Craig Stanford, John S. Allen, and Susan C. Anton say that in 1974 Donald Johanson and his team discovered Lucy, the famed skeleton of Australopithecus afarensis. She stood a little over a meter tall and possessed a cranial vault suggesting a modest brain size about equal to that of an adult chimpanzee. The cranium and teeth of afarensis are intermediate in appearance of a modern chimpanzee. The cranial capacity is small but slightly larger than that of a modern chimpanzee. The afarensis face was prognathic, but not so much as in the modern chimnpanzee, and the cranial base was relatively flat, similar to that of modern chimpanzee. Cranial crests, flanges of …show more content…
According to “Faithful Ancestors” Bruce Bower discusses the claims of monogamy of A. afarensis. Also, modern humans, chimpanzees, and gorillas confirm that this technique is accurate and that skeletal size dimorphism in A. afarensis was most similar to that of contemporary Homo sapiens. These data eliminate some apparent discrepancies between the canine and skeletal size dimorphism in hominoids, imply that the species was not characterized by substantial sexual bimaturation, and greatly increase the probability that the reproductive strategy of A. afarensis was principally

Lucy

...Abstract Covering Lucy’s discovery, her physical attributes, and the astounding significance of Lucy to the human family tree; this paper was written to explain it all and educate the audience on what a crucial puzzle piece Lucy has come to be to anthropologist everywhere. First I will explain who found Lucy, where she was discovered, and when she was uncovered. I will then write about Lucy herself. I will describe her age, size, and how her gender was determined. Last but not least, I will explain how we know Lucy is a hominid, where she lies in the hominid line, and the significance of Lucy’s discovery to anthropology. Lucy On the morning of November 24th, 1974, Dr. Donald Johanson found the remains of a hominid that would shake the world of anthropology. Then a University professor, Johanson was on an expedition to Hadar, Ethiopia. Although this site was a proven haven of early fossil remains, Johanson had no idea he was about to make the discovery of a lifetime. Dr. Donald Johanson’s discovery of Australopithecus afarensis in Hadar, Ethiopia is a crucial piece to the puzzle of the human family tree. In this paper, I will not only discuss the 3.18 million year old “Lucy”, but I will also explain the significance of her revolutionary discovery to the world of anthropology and the hominid line. Being several weeks into his third expedition to Hadar, Ethiopia, finding Lucy was no small feat for Dr. Johanson. At the time, Johanson was a professor at Case Western...

Laetoli Footprints Research Paper

...footprints in three different ways. First, the background of the Archaeologists and the discoveries leading up to the Laetoli footprints because these people found many interesting things that surrounded the footprints, and it was interesting how long it took them to actually find these footprints. Secondly, I will be talking about the actual discoveries of the footprints, because not only do they use dating methods that we learned about but they are also interesting to look at because of their distinct size but very familiar stride. Lastly I will talk about the significance of these footprints, not only did it prove the hypothesis to be true, but it also has many other importance that helps us learn about our past. First I will start off this paper by telling you the background of the dig. As I said it was interesting to see how long it took them to find these footprints, but also it was just as fascinating to see all of the discoveries around it as well. The start to this very important discovery goes back to 1935 when a man named Sanimu convinced an archaeologists named Louis Leakey to look at the area in a place called Tanzania, which is located in East Africa. There he found several mammalian fossils along with a left lower canine tooth, but they didn’t think it came from a human. Then in 1938 a German archaeologist Ludwig Kohl-Larsen found numerous remains which include; premolars, molars, incisors (pointed tooth). These remains showed to be from hominid species which just mean...
