Out of Africa vs Multiregional Theory

Science researcher Christopher Stringer and science writer Robin McKie state that modern humans first developed in Africa and then spread to other parts of the world.

The Multiregional theory believes that our earliest ancestors came from Africa, later settling to different parts of the world. It was believed that after a while Homo Sapiens evolved from distinct groups of Homo Erectus from all over the world. As they spread out there was a “mixing” of species such as homo Erectus and neanderthals. As time passed we eventually evolved and got to modern humans. There are different traits for each group or people around the world. The pattern of human evolution is described as Multiregional

The book The Human Story by James C. Davis is about the way humans evolved from Homo erectus to where we are now. The book starts off by telling us how archaeologists found paintings in caves leading all the way back prehistoric times. These people were mainly from Africa and spread all across the world just because they followed herds of animals which they lived off of. They spread from Africa to Europe and Asia, from Asia they followed the herds across a land bridge to North America and all the way down to South America. They were also able to reach Australia and the island surrounding it. After a couple thousand of years they began to settle down into civilizations. These civilizations included Athens, Sparta, Sumer, Egypt, and China. We

1.1) The MRC theory says after the first migration from Africa 1.8 million years ago, the different groups of humans in different part of the world slowly evolved in parallel with each other. The emergence of modern humans didn’t occur in a single area, but on different continents. In contrast, the OOA theory says humans evolved first in African and then migrated to different continents. The Neanderthals and Homo Sapiens evolved into different species and interbreeding would be rare which is why there are different races. The only similarity between the two theories is that humans started in Africa. Until about 14 years ago, Genetic DNA showed that the MRC theory was correct. But 13 years ago more evidence shows the OOA theory is more realistic. Anatomical evidence shows different physical characteristic between Neanderthals and Homo Sapiens. Archeological

It's widely agreed by scientists that Neanderthals and Homo sapiens (modern man) are different species. However, it's thought that 1.5 - 2.1% of DNA from anyone born outside of Africa is Neanderthal which means that they co-existed and interbred with our Homo sapien ancestors approximately 35,000 years ago. Researchers say, the only human ancestors who didn't interbreed with Neanderthals were sub-Saharan Africans. Neanderthals typically lived in Europe and Asia up until approximately 33,000 BC when they are said to have become extinct. They lived during the Ice Age and can be considered as early cave men who are likely to have been covered in hair and had an ape like appearance very similar to the conventional perception of Bigfoot. Their eyes and brains were larger than those of Homo sapiens but they were sophisticated enough to carry tools, make fire and bury their dead. One scientific explanation as to why the Neanderthals died out is climate change, More likely, they were unable to compete with the better adapted early humans who either killed them, took over their land or interbred with them and they were absorbed into our

Chris stringer is the author of Lone Survivor How We Came to Be the Only Humans on Earth. Stringer covers a wide variety of topics in his book. He talks about the modern technology we have now that makes it easier to identify fossils, bones, dates, etc. He also mentions how the human gene became what it is today, the Homo sapien. Stringer argues that Homo sapiens did not originate in a single region of Africa. Instead, different populations coexisted across the continent with other species like Homo erectus, and they exchanged genes, tools and behavioral and survival traits before they migrated to Europe.

Neanderthals and modern humans coexisted for well over 100,000 years.  Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.  Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.”  What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.

The Multiregional Continuity Model states that after Homo erectus left Africa and spread into other parts of the Old World, regional populations gradually evolved into modern humans. In contrast, the Out of Africa Model states that modern humans evolved fairly recently in Africa, migrated into Eurasia and replaced all

The Out of Africa Theory is a widely renown theory describing the origin of the human race and their early dispersal throughout the world. According to this theory, humans have a monogensis, or a single and common origin; Africa. The concept was first introduced in 1871 by Charles Darwin but was deliberated for years until further studies of mitochondrial DNA and evidence ”based on physical anthropology of archaic specimens” was added.

Some scientists believe (Duarte et al., 1999) that Neanderthals and modern humans not only interbreed in Europe but Neanderthals are the biological and cultural evolutionary transition between archaic and early modern

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 line of human development because other parts of the world do not have evidence dating back as far as in Africa. Where did humanity and human history begin? There are theories supporting both that, humans evolved from various parts of the world, and that humans rose in Africa then migrated to other parts of the world and continued to develop. The theory that has the most support is that humanity rose in Africa then moved to other regions of the world. Africa is indeed the home of humanity but because Africa is where humanity began they were not able to be at the top of the evolutionary ladder because their global location did not allow them to develop faster. Human history in general is difficult to understand but we can look at the past to learn more about where we came from and how our societies have developed.

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. The second theory I will discuss is the climate change theory, which claims that Homo sapiens lived while Neanderthals died because they were better adapted to the climate. The last theory I will discuss is

Human evolution is the gradual process in which people, or Homo sapiens, originated from apelike ancestors. Scientific evidence, particularly in the form of fossils and secondary remains, show that the physical and behavioral traits shared by all people evolved over a period of approximately six million years. Humans are primates. Both genetic and physical similarities show that humans and the great apes (large apes) of Africa, chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas share a common ancestor that lived between 8 and 6 million years ago. The volume of fossils found in Africa suggests that most evolution occurred there and is likely the place of origin for early humans. This brings to fruition the “out of Africa” theory, also called the “single-origin hypothesis.”

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. The rivaling opinion, entitled the “regional continuity” theory or “multiregional evolution” model refutes this theory and states modern humans evolved from various species of Homo erectus who interbred with others that lived in

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.
