The Origin Of Modern Human And Their Settlements Caused Controversy

The theory was broken down into two parts of the world, Southern and Northern Cradle. The southern cradle is located in Africa and Northern in Europe. This theory was explained how the human species originated in Africa in the area of Kenya and Ethiopia and over time, man left Africa over 40 thousand years ago and ended up in Europe. With evolution over 20 thousands years, man makeup changed to accommodate the harsh living environment during that time of glaciation. The climate was very cold and man

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

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.

There was a question leaved me confused at times. Where did I come from? Where did human come from? I heard many religious stories about the origin of human. However, those legends cannot solve my doubts. After I took this anthropology class, I got my answer. Modern humans evolved in Africa. Moreover, I learned that our bodies also contain small percent Neandertal DNA. What was the Neandertal? Neandertal, the scientific name of which is Homo Neandertalensis, existed roughly between 200,000 and 30,000 years ago. They lived in Europe eastward to Central Asia. In fact, in the past, scientists always thought that Neandertals were more likely brutal and stupid apes. However, Neandertals were smart like modern humans and owned their special

The scientists involved in the project took the sample of 12,127 men from 163 different Asian populations including Iran, China and Siberia. This experiment looked at the modern human DNA patterns that define the Y chromosome. According to past studies, the Y chromosome remains constant through time and can be utilized to help trace a male’s ancestors. The results from this experiment are overwhelming and very exciting to those in the scientific community who support the Out-of-Africa theory. These results show that every man who participated in the study had one of three Y chromosome biallelic markers or mutations labeled YAP+, M89T, and M130T. These three mutations all connect back to one mutation called M168T which originate in Africa around 35,000 to 89,000 years ago. For the regional continuity theory to be proven valid, one of these 12,127 men would have not had one of these mutations but a completely new and different mutation. This could have suggested a possible lineage to another type of Homo erectus living in Asia or interbreeding between different human-like species. This may become possible in the future and prove this current study false. However, at the present time, this indisputable information resolves that there is not as much evidence to support the theory of regional continuity or else there

“Despite intense research efforts, no consensus has been reached about the genetic relationship between early modern humans and archaic human forms such as the Neanderthals” (Serre, 16 March 2004). It is a

The Journey of Man was an interesting non-fictional anthropological literary piece where the author sought to explain how modern humans came to inhabit the world we know today. He began by talking about the mitochondrial DNA passed from mother to daughter, or the maternal line. Using this it was discovered that all people had a common female ancestor who lived in Africa about 200,000 years ago. This was one of the first steps in supporting the out of Africa hypothesis. However, mtDNA could not give all the answers to how humans moved throughout the world, and for that he turned to the male Y chromosome. By examining this, he and many other geneticists discovered the different changes throughout populations, and could estimate how long ago they occurred. According to Wells, modern humans were in Africa 60,000 years ago, and from that point began to migrate outward. For each new area, such as Asia, the Middle East, Australia, and others, there were specific polymorphisms on the Y chromosome that defined each population. By using this technique, he was able to map out when modern

The dispersal theories evidence agrees that bipedalis homids first came out in africa until.15mya & that H.erecus was the first hominin to migrate out of africa. By 20,000 mya the only one left alive was h.sapiens. The out of africa hypothesis is that H.sapiens evolved from the H-erectus that remained in Africa. They left Africa and replaced other species, with little interbeeding between them. Those existing species (e.g NEanderthals, Denisovans) were quite genetically isolated from the evolving H.sapiens.

One of the most fiercely debated issues in paleoanthropology points at the origins the primate species. The top two continents that have been very evident in our origins that can be traced to Africa and (Eur)Asia. African origin stresses the multiregional continuity theory it suggests a single origin for modern humans and gives an explanation to the Out-of-Africa model for the patter of our human evolution.

For many years, scientists have studied Neanderthals. Some scientists have led to believe that Neanderthals play a special role in the genetic makeup of modern day humans. In the article, Ancient gene flow from early modern humans into Eastern Neanderthals, it says that recently it has been shown that Neanderthals contributed genetically to modern humans outside Africa 47,0000-65,000 years ago. In this article Neanderthals and Denisovan, (an extinct species of human in the genus homo Alta) are analyzed from the Altai Mountains in Siberia together with the sequence of chromosome 21 of two Neanderthals from Spain and Croatia. In their research they discovered that a population that diverged early from other modern humans in Africa have contributed

Accordingly, the facts being gathered are not from changed DNA or other interfering features. The genealogical family tree has an abundance of diversity, taking into account the influence of overcoming land obstacles and geographical challenges. The analysis was procured through substantial evidence of mitochondrial DNA. The debut of polymerase chain reaction solved the barrier of relying on black Americans, in substitute for Africans circa 1980’s. Consequently, a study entailed a genealogical tree that contained 14 deepest branches solely linked to Africans and the 15th branch led to both Africans and non-Africans; further verifying the probability of the African origin

In the documentary “The Journey of Man”, Spencer Wells goes on an expedition to map out the begging of human migration out of Africa. He plans on doing this by finding and obtaining blood samples from the various tribes around the world. It is believed that the first living being was from Africa. “According to the recent single origin hypothesis, human ancestors originated in Africa, and eventually made their way out to the rest of the world. Analysis of the Y chromosome is one of the methods used in tracing the history of early humans. Thirteen genetic markers on the Y-chromosome differentiate populations of human beings” (Journey of Man: A Genetic Odyssey). In additions it is also believed,” on the basis

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.

Apes play a big part in the idea of our where we first came from. It is said that apes are the ancestors of the first humans. Chimpanzees also could be our ancestors. Scientists did studies and found out that 98% of the DNA from a ape is the same as In humans. Scientist believe that people came from Africa, the thought of us coming from Africa is called the, African Theory. This theory is only one of many theories about where humans came from. There were also many theories

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.”
