Louis Leakey Essays - Louis Leakey, Mary Leakey, Anthropology, Kenya

Louis Leakey Louis Leakey Discovering the Secrets of Humankind's Past Louis Leakey was born to be an archaeologist, for his childhood in Africa truly prepared him for the field life he would later lead. The son of missionaries Harry and Mary Leakey, Louis grew up in Kenya near Nairobi, among the Kikuyu African tribe who the elder Leakeys were trying to convert. Despite intervening periods in which the Leakeys moved back to England, Louis grew up practically as a Kikuyu tribe member, and at the age of eleven he not only built his own traditional hut in which to live but was also initiated as a member of the Kikuyu tribe. It was within this hut that the beginnings of Leakey's archaelogical aspirations took place. In one section he started a personal museum, collected all things naturalistic, from bird eggs to animal skulls. It was in 1916, at the age of fourteen, when Leakey first truly realized that he was meant for archaeology; after reading the account of stone-age men entitled Days Before History he was hooked. After reading about the arrowheads and axeheads created by these people, Louis began collecting and classifying as many pieces of obsidian flakes and tools as he could find. After confirmation by a prehistory expert that these were truly stone tools of ancient Africans, truly links to the past, Leakey knew that the rest of his life would be devoted towards discovering the secrets of the prehistoric ancestors of humankind. Despite not being accustomed to the school structure back in England and the accompanying problems he had in public school, Leakey was accepted into Cambridge in 1922. However, blows to the head sustained during rugby games resulted in epilepsy and headaches for Leakey, and he had to leave school in 1923. This, however, was a blessing in disguise, for Leakey landed a job as an African expert on an archaeological mission to Tendaguru in what is now Tanzania. He was to accompany the archaeologist and dinosaur bone expert William E. Cutler. With his fluency in Swahili, Leakey soon orgainized an entire safari to the site. Working with and observing Cutler, Leakey learned more about the technical side of the search for and preservation of fossil bones than [he] could have gleaned from a far longer period of theoretical study. Many dinosaur bones were dug up although a complete skeleton was never found. After several months Leakey was forced to leave, leaving Cutler to continue. Back in En gland, Leakey wrote many articles and letters about the dig. Cutler, however, died in Africa a few months later, a victim of Blackwater fever. Leakey returned to Cambridge and studied anthropology. From these studies and independent ones, Leakey developed the view that early man had originated in Africa, not in Asia as most scholars believed at the time. He became fascinated with the Olduvai Gorge site and the Homo sapiens skeleton discovered by German paleontologist Hans Reck. Great controversy surrounded Reck's find because the age of the skeleton could not be proven. Further, Reck could not return to the site because, as he was German and Britain had won that region of Africa in World War I, he was not able to go there. Leakey was fascinated with the site and told Reck that they would one day go back. For the time being, this had to be put on hold. Finishing finals, Leakey graduated with excellent marks and recieved many grants for research in Africa. He was twenty-three, and he was about to lead his own expeditions. Over the next few years Leakey dug at many sites, finding many stone tools, animal bones, and other artifacts. His search, however, was for proof of the use of a specific Chellean hand-axe style found in other parts of the world. This he found in 1929, and its discovery pushed back the age of the Great Rift Valley in Africa a great deal. Further, it provided critical evidence for a level of sophistication in East Africa equal to that of European cultures at the time. By this time Leakey's work at caught the attention of the archaeological community and he began to receive much acclaim. In November 1929 he returned to England with a

Women on the front lines essays

Women on the front lines essays Can women meet the physical requirements as men? In most cases no, they can not. As you have seen day in and day out the standards for hiring women are being lowered. Women are considered a minority in todays world along with every ethnic group there is now present in our society. But lowering the standards for women also bring in individuals who are not capable to do the job or even have the right classifications to ensure the safety of the coworkers as well as the public. There should not be a standard for one classification such as men and different one for others. If the job can be done to the standards it was originally set for, there should be no deflections from those standards. We have seen in WWI, WWII, Vietnam, Korean, Gulf wars which no or a minimal amount of women serve on the front lines. Most women were not brought up to be in combat, things may be changing to accommodate some women but we are close to providing this type of employment for women and mothers who have children at home as well as major responsibilities to who they are accountable for. There shouldnt be any questions when our men or woman are providing the service which is the outmost one can give!!!! Most women feel that since only men are serving in the military it is a discrimination against women. As you know already the lawsuits which have been present in courts now and in past years have made women a more powerful influence in our society. Therefore providing them with a tool which gives the women of today an equal ability to do as men do in there everyday life; this in turn gives them the right to serve in the military. As for military service physical standards, which give women more of a chance to serve the military, they shouldnt lower their requirements for women so they can pass just for them to feel ...

Nuclear Power Essay Example | Topics and Well Written Essays - 500 words

Nuclear Power - Essay Example One of the ways is through the use of renewable resources such as wind and hydraulic power. However, there are limitations to these alternatives and this is one of the reasons that nuclear power has become an increasingly used resource, but many countries are fearful of the powerful and destructive nature of nuclear power. Nuclear power operates on the principle of nuclear fission. The process of nuclear fission is the bombardment of large molecules in order to split the nucleus. The splitting of the nucleus causes an enormous release in energy. As the elements undergo more and more of the process of nuclear fission, toxic chemicals are produced in the reactor, which must be stored away for extremely large periods of time in order to prevent radiation exposure. Even though there are numerous safeguards designed to protect the reactor in case of a breach, there have been huge nuclear disasters that have left the global community apprehensive about the proliferation of nuclear energy technology. The nuclear meltdown at Chernobyl is considered to be the worst nuclear reactor accident in history. An explosion in the core reactor of the building lead to the proliferation and spread of dangerous radioactive material into the atmosphere, spreading across the Soviet Union and Western Europe. At first the Soviet Union did not report on the incident until countries started seeing the effects of the radiation fallout. There was also contamination in the water supply that had to be accounted for since the plant was near a river system. In addition to the people killed at the plant, there were mutations and cancers associated with the exposure to the radiation as it proliferated across the globe (Berger, 2010). In addition to Chernobyl, the only other level seven disasters occurred at the Fukushima Daiichi nuclear disaster. Unlike Chernobyl, the precipitant to the nuclear disaster resulted in an earthquake, which damaged the systems.
