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. Stringer and Andrews argue that genetic and paleontological evidence supports a more recent Out-of-Africa model as opposed to a more drawn out Multiregional method that also incorporates gene flow (1263). In contrast, Wolpoff, Hawks, and Caspari claim that the Multiregional model is misunderstood, and clearing up discrepancies could bolster support for this theory instead (129). Pearson notes that while people like Wolpoff et al defend the Multiregional model, archaeological evidence seems to show that likely no intermixture between modern Homo sapiens and other archaic hominins happened during the spread of early Homo sapiens out of Africa (145). It is easy to see that the debate lingers onwards with an end not clearly in sight. This paper will further examine the arguments asserted by these authors and identify their core arguments, the data they use to support their arguments and determine which paper is the most convincing of the three.
According to Stringer and Andrews, the Out-of-Africa Model suggests that there is a fairly recent common ancestor that shares many of the anatomical characteristics displayed by modern Homo Sapiens (1263). This version is more parsimonious with regard to the fact that it ...

...uestion, we will be able to extend research about why humans came from where they did as well as know where to expect the fossil record to lie. Without debates like this one, the research community could lay stagnant, but instead these debates promote new motivations to answer the ever-human desire to know.

The Origin Modern Humans Essay

- The origin of modern humans is a matter of debate. There are two different theories regarding the origin of modern humans or Homo sapiens. The first and primary theory states modern humans emerged in one place and from a single origin. This theory is known as the Recent African Origin Model. It suggests that modern humans are the product of speciation during the late Pleistocene in Africa. Homo sapiens eventually migrated out of Africa to Eurasia, and replaced all other human populations, without interbreeding....   [tags: Anthropology]

Modern Humans Are The Only Ones Who Exists Today Essay

- In the Pleistocene Era, hominins have been expanded rapidly in terms of survival, such as availability of food resources, migrating and how they defend their territories. Then, this has been lead hominins to develop intelligence and create a wide variety of tools. However, there is no specific evidence or answer to, how did human beings evolve and where did they come from. Environmental conditions or pressures have been played importantly, that contributed to the selection of the genus Homo in Africa, Europe, Asia, Australia, and there is an anatomical evidence over the past one million years, culminating in our modern genome; leads to developing human cognition and explains why modern human...   [tags: Human, Human evolution, Archaic Homo sapiens]

Essay on The Course Of The Origin Of Man

- The Course of the Origin of Man Humans have wondered for years where they came from. They have searched many sources: the bible, novels by Charles Darwin, to long told stories passed on by the generations. Ideally we can look at two different schools of thought the first stating that the different races of humans evolved independently of one another or that they all sprang from a common source. Over the years science has lead us to new discoveries, with the finding of fossils, ancient tools, and DNA....   [tags: Human, Human evolution, Evolution, Africa]

Prejudice: A Problem With an Unknown Origin Essay

- ... After examining the test results, they discovered that monkeys stared longer at monkeys outside of their group. The test monkeys stared less at the monkeys who recently joined the group because they did pose a threat. Psychologist Catherine Cottrell and Steven Neuberg believe that prejudice became wired in us when we started to live in groups. The psychologist said, “To protect ourselves, we developed ways of identifying who belongs to our group and who doesn’t” (Grewal 2). The monkeys and humans have developed in a way that being prejudice towards outsiders is a natural part of how we form and distinguish groups....   [tags: ongoing problem in modern societies]

Essay about The Evolution of Modern Humans

- While time travel still remains elusive to us, scientists have been able to discover things about our past as a species that were practically inconceivable over 150 years ago when Charles Darwin released his book entitled The Origin of Species. They have especially uncovered many pieces to our still incomplete puzzle over the past 20 years so that we now have a nearly complete idea of how our species Homo sapiens came to be. This story of our history includes dozens of species’ and hundreds of fossils and bones, yet fairly few complete or even partial skeletons....   [tags: Homo Sapiens]

- The Debate Over the Origin of Modern Homo Sapiens There has been a great deal of heated debate for the last few decades about where modern Homo sapiens originated. From the battle grounds, two main theories emerged. One theory, labeled “Out-of-Africa” or “population replacement” explains that all modern Homo sapiens evolved from a common Homo erectus ancestor in Africa 100,000 years ago. The species began to spread and replace all other archaic human-like populations around 35,000 to 89,000 years ago....   [tags: Anthropology Essays Paleontology Papers]

The Mystery of Human Origin Essay

- The Mystery of Human Origin The mystery of human origin is an often-debated topic. It is an issue that can never be proven, something as vague as the existence of God, the proof of a human soul, or even as evasive as the human psyche itself. The debate itself is divided between two main camps: the Evolutionists, who concur with Darwin's theory of evolution, survival of the fittest, and natural selection. They believe that mankind evolved from earlier versions of hominids, which in turn evolved from earlier primates....   [tags: Papers]
