The Origin Of Modern Human Form

Humans developed in Africa. “…, indicates that the earliest stages of human evolution were also played out in Africa.” (Page 36)

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.

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.

Evolution is the process of change of living organisms over a long period of time due to difference of environment or circumstances that was not prevalent before. These evolutionary mutations occur due to things such as a change of environment where what may have been shallow water has gradually gotten deeper and thus the organisms that inhabited that land had to change in order to remain living in that area without risk. This also relates to things such as storms that may alter the habitat of the previous land where what something may have eaten has changed and the organism was altered to match that environment. This then has an affect on the history of human evolution, humans and apes relate to a similar origin and were very similar many years ago and this is known as primate phylogeny. This Extended research task will go in depth with the origins of man and the relation between man and apes through primate

According to physical evidence, and theories, scholars have concluded upon a whole hypothesis. Based on their knowledge and belief, modern humans diverged from Homo sapiens between 200,000 and 150,000 years ago specifically in Africa, that between 125,000 and 60,000 years ago members of Homo sapiens left Africa, and that these

I agree with you James that the complete replacement model or Out of Africa model suggests that modern humans were firstly originated in Africa from a single group of Homo sapiens approximately around 200,000 years ago, which they continuously evolve then migrated out from Africa, then spread out into the broader world throughout Eurasia, which replaced other archaic humans, such as Neandertals in Europe. Researchers like Stringer and Andrew supported this due to the evidence they have shows that the identified oldest fossils of Homo sapiens originated from Africa, and also, a variety of various DNA studies on modern human populations all suggest that common lineage from a small gene pool was derived in

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.

As human beings, we have our own general understanding of how our world came to be. Whether we are in church, the synagogue, or the temple humans have established ideologies. Humans use the creation myths to bring about some understanding as to how humans magically or purposely inhabited the earth. However, even though myths satisfy this yearning for how and why, the scientific world revolted with the idea that creation myths are no longer satisfactory. In unison paleoanthropologists and archeologists along with many other historians said that we as humans need a scientific, concrete, and factual basis for our existence. As a result of many years of research and discovery the scientific world came to two conclusions. Either “Homo erectus evolved into Homo sapiens in each region of migration (Spodek 16)” most notably known as Candelabra. Or the “Homo erectus evolved into Homo sapiens only once- in Africa (Spodek 16)” most notably known as the Noah’s Ark model. Through my journey of understanding both schools of thought I began to rethink the basic sugar coated origins of humanity that teachers spoon feed in high school. Spodek along with the associate authors shined a little light on the fact that Homo sapiens most likely stemmed directly from Africa and migrated to other places in the world. Which leads me to my thesis: Homo erectus evolved into Homo sapiens only once in Africa, and then emigrated to the rest of the world.

All men and women can be traced back through DNA to two homo sapien sources, one male and one female both in Africa. This strongly supports the out of Africa theory. Also there is wider genetic diversity among those in Africa compared to those in the rest of the world. This shows that there is a larger genetic pool in Africa which again points to the out of Africa theory.

INTRODUCTION There are several competing theories for the origins of human evolution. The multiregional hypothesis and the recent single-origin hypothesis (also known as the ‘Out of Africa’ model), are two of the most dominant. Each hypothesis shows a different origin which has been deduced from evidence found in fossil records, DNA sequences and archaeological sites. Ref 2,11,12,16 plus general uni book about human evolution( u find a title) OUTINE OF MULTIREGIONAL HYPOTHESIS The multiregional hypothesis (an idea of Alfred Russel Wallace and Ernst Haechel, furthered by Franz Weidenreich 1873-1948) proposes that modern humans evolved simultaneously in all regions of the world.

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

The theories of human evolution may always cause a heated dispute. Each theory presents its own evidence proving

The origin of modern human and their settlements caused controversy with two different hypothesis. One is ‘Out of Africa’ hypothesis, confirm that all modern humans stem from a single group of Homo sapiens who emigrated from Africa 2,000 generations ago and spread throughout Eurasia over thousands of years. These settlers replaced other early humans (such as Neanderthals), rather than interbreeding with them. The second hypothesis is Multiregional that Homo sapiens is the evolution from Homo erectus, and that evolution took place in many parts of globe independently. Genetic studies and fossil evidence show that archaic Homo sapiens evolved to anatomically modern humans solely in Africa between 200,000 and 60,000 years ago. Hence the ‘Out of Africa’ hypothesis, that modern human stem from Africa is recognized. The human family was born in Africa, and many millions of years passed before we have any evidence that hominids had managed to escape the continent’s confines and went to conquer Asia and Europe.

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.
