Australopithecus Afarensis
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
Australopithecus afarensis existed between 3.9 and 3.0 million years ago. The distinctive characteristics of A. afarensis were: a low forehead, a bony ridge over the eyes, a flat nose, no chin, more humanlike teeth, pelvis and leg bones resembled those of modern man. Females were smaller than males. Their sexual dimorphism was males:females; 1.5. A. afarensis was not as sexually dimorphic as gorillas, but more sexually dimorphic than humans or chimpanzees. A lot of scientists think that Australopithecus afarensis was partially adapted to climbing the trees, because the fingers and toe bones of the species were curved and longer than the ones of the modern human.
A. afarensis is classified as an ape, not a human. It is a Hominid, which is an ape closely related to human beings. The first fossils of a skeleton were found at Hadar; a site in northeastern Ethiopia. The team named the skeleton “Lucy” after the Beatles song, “Lucy in the Sky With Diamonds.” In terms of overall body size, brain size and skull shape, "Lucy" resembles a chimpanzee. However, A. afarensis has some surprisingly human characteristics. For example, the way the hip joint and pelvis articulate indicates that "Lucy" walked upright like a human, not like a chimp. This means that upright posture and bi-pedalism preceded the development of what we would recognize as human beings and human intelligence.
All non-human primates sleep in the trees at night. So, it would seem to be that A. afarensis slept in trees also. Their skeletal structure agrees with their arboreal lifestyle. “The large premolars of A. afarensis suggests they were frugivores, and the thick enamel on the teeth suggests they may have eaten nuts, grains, or hard fruit pies” (Boyd and Silk, p.

The Gallipoli campaign was a military disaster but it is still one of the most important conflicts in which Australia was involved. On 25th April 1915 between 4:30 and 6:30 am the Gallipoli Peninsula was invaded by British, Australian and New Zealand forces. This was to start the long, hard weeks in which the troops were fighting for ground that the enemy controlled in Turkey. They were attempting to gain a supply route to Russia to aid them in repelling the German and Turkish soldiers from their country. I will be discussing the willingness of Australians to volunteer for the war effort and the love and respect they had for their Mother Country, England. I will also discuss how the young, naive soldiers arrived at war not knowing what warfare entailed. They were shocked by the conditions and casualties. I will also discuss the bravery that was shown by the ANZACS in the most dangerous conditions. I will conclude with my reasons of why the Gallipoli campaign holds such value and importance in Australian history and ideology.
...s much of the time that some people have been led to believe. This belief had begun when they had discovered a fossil that has since been given the title “Selam”. “Selam” is the skull of a three year old female Australopithecus Afarensis who is believed to have been alive about 3.3 million years ago, having been discovered in the year 2000 in Ethiopia, Dikika by a paleoanthropologist named Dr. Zeresenay Alemseged. With Selam they have found that with the skeleton of her, that it shares many similarities when compared to the bone structure of an ape, meaning that the A. Afarensis may have lived a somewhat arboreal lifestyle. They at first checked the shoulder blades of “Selam”, with both remaining in fully intact which is considered to be very rare due the fact that the shoulder blades had remained intact through 3.3 million years, as it would allow them to find out
After analyzing the remaining family group, their appeared to be a difference in size among the discovered fossils. Johanson claimed that all the remains found belonged to one species; however, other anthropologists and scientists disagreed and believed that two or more were from different species. The analysis of Lucy’s knee joint indicated that cranium, mandible, dentation and postcranial skeleton contained unique characterizes, which resembled in a large degree the ones in a human being, and also indicated bipedal locomotion.

Australopithecus afarensis who existed 3.5 million years ago and a 4.4 million year old skeleton of an Ardipithecus ramidus are the closest science has come to discovering the human lineage. Shattered Ancestry an article written by Katherine Harmon discusses the remains of two hominids found within Ethiopia. These skeletal remains have created a huge controversy within the topic of evolution questioning many assumptions that have been made referencing the human lineage. The skeleton of the Australopithecus afarensis was named Lucy and was discovered in 1974. The evidence of her walking upright on her two feet essentially guaranteed her a spot in the human lineage line. Lucy was a chimplike ape that was said to walk upright making scientists believe the human ancestry was simple. The complete skeleton found in Ethiopia of an Ardipithecus ramidus named Ardi completely changed all assumptions made from scientists about the complexity of the human lineage. These remains have encouraged researches that the human line is not the only lineage to have evolved but the chimpanzee line has undergone drastic changes as well. There are many traits that researchers have always directly linked to the human lineage however since these discoveries occurred researchers are reconsidering. The recent discoveries that have shattered what has always suggested what linked a species to the human lineage have changed the certainty of whether it is possible to confidently identify the human’s last common ancestor. Majority of scientist had forgotten that there would have been many hominid species living together at one time. New theories have been suggested since scientists revealed that the foot of a hominid found called the Burtele site was found ju...
As archeological discoveries of bone fragments and fossils continue to support the existence of homo-sapiens
At the onset of World War 1 in 1914, the ‘sick man of Europe’ known as Turkey, or the Ottoman Empire, sought foreign financial aid after the stress of the Balkan Wars. The belligerents of World War 1 saw an opportunity in the Ottoman misfortune, as a Turkish alliance equated to control of the Dardanelles Strait near the peninsular city of Gallipoli. To the Allies consisting of Russia, Britain, and France, the Dardanelles was Russia’s primary contact route, and also facilitated the movement of 90% of Russia’s grain exports and 50% of Russia’s exports overall. Conversely, to the Central Powers of Germany and Austria-Hungary, control of the strait posed a major threat to the Allies. When Britain failed to deliver two battleships which Turkey requested, Germany was quick to deliver a gift of two German battleships to the Dardanelles Strait. Turkey accepted Germany’s gifts, closed the strait, and secured their active role in the war. The Allies would soon arrive to regain access to the strait, and Turkish Soldiers bore the responsibility of its defense. Of all Turkish military leaders, the young Lieutenant Colonel Mustafa Kemal earned a reputation as the most competent leader at driving the operations process. Mustafa Kemal effectively understood, visualized, described, directed, and led operations at the battle of Gallipoli to defeat Allied forces.
During an excavation in the middle Awash Region of Ethiopia, Haille- Sellaise unearthed six hominid teeth. These were at first thought to be the fossilized teeth of
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.
Corns and calluses: these forms where the skin becomes harder by developing thick layers to protect itself from pressure and friction. The difference between corns and calluses, is that calluses develops in weight-bearing areas, likes the soles of the feet, whereas, corns are develop on top and sides of feet, smaller than calluses, painful.

“As a base for air warfare against Great Britain in the Eastern Mediterranean, we must prepare to occupy the island of Crete. For the purpose of planning, it will be assumed that the whole Greek mainland including the Peloponnese is in the hands of the Axis Powers.” This quote is a direct reflection of the growing need and concern for terrain to support future operations in the Mediterranean area made by Adolph Hitler in Directive No. 28. In 1941, it had become clear that the Mediterranean area is becoming an extremely decisive area for both sides to influence the future of the Second World War. The Germans saw that by taking Crete it would prevent the British forces from hindering operation in the Balkans that would further influence their attack on the Soviet Union planned for the summer of 194...
Austalopithicus meaning “southern ape” was the first specimen to be found. The Austalopithicus was found in African and was know to have lived from 4.2 to around 1.0 million years ago (Standford 251). They had a small body like an ape that would get approximately 64 to around 100 pounds. They had a big jaw with a U-shaped mouth of small teeth. The brain size of a Australopithicus was small and would get approximately 340 to 500 cc, which is in the same range as gorillas and chimpanzees brain sizes. The top of their skull was of a bony ridge. They were able to walk on their two feet and had a small pelvis. The Australopithecus were found with stone tools, which made them the first stone tool makers.
