Homo sapiens neanderthalensis (Homo neanderthalensis) The Neandertals are the most controversial human ancestors that have coused many confusion in the past century and a half. In chapter 12 page 287 The origin, evolution and dispersal of modern people, discovery of the Neandertal in Feldhofer Cave was the first and famous one. It was featured in the Decoding Neandertals video. https://www.youtube.com/watch?v=tevSkylmvXk These Homo species existed between 230,000 and 30,000 years ago. â€Å"According to one theory, Neanderthals, Denisovans, and modern humans are all descended from the ancient human Homo heidelbergensis. Between 300,000 to 400,000 years ago, an ancestral group of H. heidelbergensis left Africa and then split shortly after. One branch ventured northwestward into West Asia and Europe and became the Neanderthals. The other branch moved east, becoming Denisovans. By 130,000 years ago, H. heidelbergensis in Africa had become Homo sapiens—our ancestors—who did not begin their own exodus from Africa until about 6 0,000 years ago.† https://genographic.nationalgeographic.com/denisovan/ Just like Homo sapiens, Neanderthals originated in Africa but migrated to Eurasia long before modern humans did. Neandertals and Denisovans both left Africa about 300,000 years ago and settled in Europe and western Asia. Scientists discovered a 40,000-year-old adult tooth and a five to seven years old a young girls fossilized pinkie bone in 2008, in Altai Mountains cave in southern Siberia.Show MoreRelatedQuestions On The Midterm Exam1486 Words   |  6 PagesWestern counterparts. For the most part, they believed that Africans had made little, if any, progress since some humans left the continent and established themselves in other parts of the world. While this viewpoint may seem ludicrous to most modern people, Westerners actually based their claims on various theories. A major theory used to promulgate this viewpoint was the concept of Social Darwinism. This theory holds that human beings, like other organisms, ares subject to the concepts naturalRead MoreHuman Origins And Methods Used For Biological Anthropology1500 Words   |  6 Pagesorigins of human evolution; some common methods include the study of fossils, the study of genetics, or a combination of both methods. Using resent studies of fossil records from Dmanisi in the Republic of Georgia , Genetic and fossil studies of Denisovans from Siberia, and genetic studies of Neanderthals, the evolutionary history of these extinct hominids can be use to determine the environment into which modern humans evolved and its origins. In Bioanthropology, the dispersal of early homininsRead MoreThe Evolutionary Social Theories ( Teggart ) Essay1051 Words   |  5 Pagesamong peoples geographically far apart, often being different forms of mankind, we find phrases, arts, industry, social styles and customs, folk-tales, beliefs and Gods, and even literatures very much alike† (O.

Since then, questions about their relationship with modern humans have been fiercely debated between anthropologists. But what attracts most interest from scientists and popular media is the possibility of hybridization between Neanderthals and modern humans if, in other words, they were a genetically different specie or a single specie capable of producing offspring.

These species however, all lacked a cognitive flexibility which would destroy the blinding walls that blocked any connection between their multiple intelligences.

Without his speculation and theories on evolution, the way we look at evolution today may have been very misguided. Darwin created new ideas and theories that dramatically changed the way we see science today. His impact on the scientific community was both exciting yet controversial. Charles Darwin was born in Shrewsbury, England on February 12 in the year 1809. His parents were Susannah and Robert Darwin (BBC, 2015).

According to the lectures, most evidence trace to the first theory because of a few satisfying valid reasons. In the lectures it was told that â€Å"fossils of modern humans are particularly found in Africa† (Zeanah: lecture).

This is when scientists begin to disagree on how these pre-modern humans spread from Africa to other continents. Some scientists believe in the hypothesis known as the Multiregional Theory. This theory states that Homo erectus left Africa about two million years ago and from there migrated to Europe and Asia. These H. erectus then evolved, simultaneously, into Homo sapiens, or the modern looking and culturally evolved humans we are today. Another hypothesis that has beenRead MoreBiology lab Essay1805 Words   |  8 PagesHardy-Weinberg Law. The law proves that natural selection is necessary for evolution to occur (SparkNotes: population genetics, 2014). The conditions set up by the Hardy-Weinberg Law allow for variability (the existence of different alleles) and inheritance, but they eliminate natural selection (SparkNotes: population genetics, 2014). The fact that no evolution occurs in a population meeting these conditions proves that evolution can only occur through natural selection (SparkNotes: population genetics
