History And Evolution Of Africa - 850 Words
Africa played a pivotal role in human evolution. Itââ¬â¢s the site of the beginning of human evolution, as they slowly evolved from their primitive ancestors and continued to evolve for millions of years. A majority of the fossils, some dating back almost 7 million years, are found in Africa. As ancient humans migrated out of Africa they stayed close to the coast. Scientists have been able to trace their migration to areas around the Indian Ocean, South Asia, and even as far down as Australia, also referred to as Out of Africa Theory (OOA) by many scientists. By examining these fossils scientist have discovered a plethora of early human and pre-human species. In central Chad fossils of Sahelanthropus tchadensis have been discovered, dating between 6 and 7 million years. Some researchers believe that Sahelanthropus tchadensis is the common ancestors that links humans and chimpanzees. In Ethiopia Ardipithecus ramidus fossils, the earliest known biped, have been found dating back 4.5 million years ago. Bipedalism was a major shift in early evolution that many scientist attribute to climate and diet change. It arose around 4.2 - 3.5 million years ago when hominids began moving away from areas that had dense trees and foliage to savanna areas. Savanna habitats are primarily made up of tall grasses, giving bipeds an advantage; allowing them to have a new elevated eye position and reduced their exposure to solar energy. Not only did it allow hominids to be able to see over the tallShow MoreRelatedAfrica The Home Of Humanity1253 Words à |à 6 PagesAfrica the Home of Humanity Human origins, evolution, and diffusion are important for understanding the history of Africa. African historians take pride in the fact that Africa is most certainly the birthplace of humanity. There is evidence showing that humanity began in Africa by remains left behind by human groups and societies. They have retrieved fossils of living organisms, and even written records, like cave drawings. Dating back millions of years ago Africa provides the best time lineRead More Human Evolution Essay1020 Words à |à 5 PagesHuman Evolution à à à à à When people take a look at African history in general many topics and ideas come to mind. How the people of Africa lived, how they developed civilizations and cultures, and how their oral traditions came about are just a few examples. When I am trying to learn about different groups of people and different areas of the world I most likely start at the very beginning of their existence. Africa being the origin of man and the home for the majority of developments of early humansRead MoreEvolution Is The Process Of Inheriting Traits Through Dna Over Successful Generations1319 Words à |à 6 Pages Evolution is not just a story about where we came from, but an epic at the center of life itself. Evolution is the process of inheriting traits through DNA over successful generations. Charles Darwin, a naturalist and geologist synthesized a theory later known as Darwinism, which explains that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual s ability to compete, survive, and reproduce (Darwin, 1859).

It is the ability to digest milk in adulthood, conferred by genetic changes that occurred as recently as 3,000 years ago, a team of geneticists has found.The finding is a striking example of a cultural practice ââ¬â the raising of dairy cattle ââ¬â feeding back into the human genome. It also seems to be one of the first instances of conve rgent human evolution to be documented at the genetic level. Convergent evolution refers to twoRead MoreUnderstanding The Evolution, Life History, And Aids, Acquired Immunodeficiency Syndrome868 Words à |à 4 Pagesoriginated in Sub-Saharan Africa. AIDS, the result of HIV, human immunodeficiency virus, has been an ongoing pandemic for decades. Meanwhile, the first Ebola case was recognized in the 1976 and has incurred severe sporadic outbreaks but has been controlled (Rajak, 2015). While both rapidly mutating RNA viruses, several key factors have allowed AIDS, to become a worldwide pandemic while Ebola has been controlled at present (Calmy, 2015). Understanding the evolution, life history, and the socio-economicRead MoreOrigin of Man Essay989 Words à |à 4 Pagesbe correct. In reading the History of Africa by Kevin Shillington and watching The Real Eve I have come to the conclusion that the birthplace of man was indeed Africa. Early signs of humans have been trace to be founded in Africa, with the recovery of ancient bones, fossils, and stone tools. With the recovery of ancient bones that determined that humans did indeed populated Africa at one point it is hard to believe that we donââ¬â¢t come from Africa. In the case of Evolution, we evolved from primateRead MoreOn The Origin of Species by Charles Darwin915 Words à |à 4 PagesHuman evolution has been of interest to people for quite some time. Even though in the publication of On The Origin of Species by Charles Darwin in 1859 human evolution was not specifically mentioned, only that light will be thrown on the origin of man and his history, Darwin did argue for the evolution of new species from older ones (1). Since then, interest in evolution, and especially human evolution, has been growing. An example of one of the first debates about human evolution is the debateRead MoreEarly African Societies Essay933 Words à |à 4 Pages The beginning of time has always played a major role in history. The beginning of time explains the reasons for each and every creature, plant, and unexplainable phenomena that have occurred on this earth. Chapter one of World History: A Topical Approach primarily explains to the reader the different arguments that people believe are true. There are many claims that scientist have found to be very true, but then there are others who believe in a phenomenon quite different. Some scientists dateRead MoreWhat is Evolution?

You might think of evolution as a mutational problem, which fits with the situation but it is not just that. Evolution is actually the change that appears to happen in a certain population over time. When I say the word ââ¬Å"populationâ⬠I am saying it is a group of the same species that happens to share the same specific location and habitat. Evolutionary changes often occur all the time near the genetic level. What I am actually saying is that evolution is a process that will resultRead MoreThe Majestic Mammal631 Words à |à 3 Pagessurvived one of the greatest ice ages in Earthââ¬â¢s history. There were many different kinds of mammoths that evolved, and eventually, went extinct. When one studies the genus of mammuthus, they might want to look at interesting facts, the different species, how they evolved with their surroundings, and the theories of their extinction. First, mammoths were an interesting animal. They lived all over the world. At the beginning, they lived in Eurasia and Africa, but as time went on, they moved over to North
