As fossil evidence has shown, we see that all pre-human forms, from Proconsul to Australopithecines, have resided in parts of Africa. We don’t see any movement out of Africa until the appearance of the Homo erectus fossils. These fossils have been found not only in Africa, but have also been found in parts of Europe and Asia. 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 been presented is the Uniregional Theory. This theory states that although Homo erectus did migrate out of Africa into these areas, Homo erectus evolved into Homo sapiens in, and solely in Africa. These H. sapiens then traveled into the other continents and replaced the H. erectus and Neanderthals that were living there. More fossil evidence has been found to support the Uniregional theory at this time and is the most likely option for human migration. Scientists try to prove these theories using fossils found in different locations, studying what DNA can be found in the fossils, and they also look at other evolutionary theories for possible answers and clues to the peopling of the continents.
“Multiregional evolution requires the "simultaneous" or "convergent" evolution of modern humans in different isolated populations,” (Hawks and Wolpoff 89) and is based on the idea that earlier hominids, such as Australopithecines, e...

The Origin of Modern Humans Essay

- Throughout history, humans have asked many questions in regards to our own beginnings. Religion and science have examined what makes us who we are, and have tried to answer the enduring question of our own modern origins. Scientifically, theories are still debated as to when, where, and how modern Homo sapiens came to be what they are today. There are two major theories that now dominate the discussions of experts in the field of biological anthropology: the “Out-of-Africa” model and the “Multiregional” model of evolution....   [tags: Debate, Multiregional Method, Scholars]

Early Erectus Tools Found in China Essay

- Early Erectus Tools Found in China In the January/February issue of Archaeology magazine, the article "Early Homo erectus Tools in China" holds additional, yet questionable information about the foundations of the genus Homo. After recent findings of stone tools and animal bones at Renzidong (Renzi Cave) in Anhui Province, eastern China, Chinese scientists have concluded that Homo erectus may have been established there 400,000 years earlier than formerly believed, almost 2.25 million years ago....   [tags: essays papers]

Essay about Homo Sapiens and The Ecological Hypothesis

- ... Anthropologists completed studies using different species of primates in order to prove that brains in humans have indeed been evolving over time. They compared brain to body weight ratio by using a measurement of Comparative Brain Size (CBS). This ratio is independent of body size because it is the estimated sum of the size of the brain after the removal of body size percentages (Clutton-Brock & Harvey, 1980). In these studies they took into consideration variables such as the primates body weight, body length and predicted brain size....   [tags: human brain, evolution, theories]

Essay on Neanderthals and Homo sapiens

- There is evidence to suggest that Homo neanderthalensis and Homo sapiens had coexisted for approximately 35-40,000 years, (Fagan 2010) from around 60,000 years ago to 25,000 years ago when they finally went extinct (Gibbon 2001). Anthropologists are still uncertain what the cause of their extinction was. This paper will analyze three main theories of Neanderthal extinction. The first theory is the competition theory, which claims that the Homo sapiens and Neanderthals had to compete for resources, ultimately leading to their demise....   [tags: Ancient History]

Essay on How Humans Developed: The Homo Sapiens

- “The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1).

Essay about Homo Sapiens Neanderthalensis

- The Homo sapiens Neanderthalensis were present during the end of the ice age, and were very adapted to living in this cold environment. Socially, the Homo sapiens neanderthalensis were also thought to be more advanced than species of the past. Bones of this species were also very robust as well as muscular. These characteristics were first thought to be signs that they were hard-working, but these same characteristics were also found in children; therefore, it is now believed this was a genetic trait instead Visual comparisons of phenotypic traits may be misleading and do not necessarily reflect the genotype that causes them to be expressed....   [tags: Advantages, Structure, Improvements]
