Essay

Biological anthropologists have researched that humans evolved mostly in Africa, where they originated. I also agree with this since there are many fossil records of early humans, and more modern humans in Asia, Europe, Australia, and the Americas. As time passed, they evolved, climate changed, and natural selection occurred. With this climate change, populations fluctuate and mutations occur between generations. As you will see, humans have gone through much natural selection to be who we are now. More natural selection is also occurring now faster than ever and will in the future.

Next where did the humans originate from? Humans originated from Africa. But why? The reason the humans where in Africa was because they were following their food or game and they migrated. They were also called nomads because they did not stay in one place they moved around and made their way here.

Humans did not come from the Americas’ for many reasons. One of those is that plates did not connect North America and Africa at that time, another reason is that all though humans did eventually migrate out then didn’t do so at the time period when North America and Africa were connected by their respected plates. This shows how humans are not from the Americas’.

Currently, there is a dichotomy among archaeologists concerning the origin of modern humans. One main argument places emphasis on multi regional expansion of humans in which anatomically modern humans arose in multiple regions around the world. Another proposes that modern humans originated strictly from Africa before migrating to the rest of the world. While both theories have merit, archaeological evidence is in support of the Out of Africa model.

How humans got to America is a common question among social studies topic. However, we should first discuss where they came from. Humans originated from Africa which is a place that has the oldest known records of human fossils. If other, older fossils were found, this won’t be so humans couldn’t have from the americas.

No one can be absolutely sure when the first humans actually walked the Earth, only approximations can be made. Approximately 200,000 years ago species are developed in Africa. Most human species and most human biology and early culture in its broadest sense originated in Africa. Archaeologist and anthropologist may have been able to pinpoint exactly where the early human species lived and approximately how long ago they lived but are their assumptions correct? A huge part of history is based on assumption, there are many ways anthropologists and archaeologist came to these assumptions. They looked at climate, tooth decay, physical bones, and many other distinctions. These main three climate, tooth decay, and physical bones make the most sense to me, because newer and more accurate evidence can be pulled from these three distinctions.

Around 250,000 years ago humans were introduced, Homo sapiens originated in the grasslands of southern and eastern Africa.

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

The Out of Africa or African Replacement Hypothesis is a well-supported theory that argues that every living human being is dismount from a small group in Africa, who then distribute into the wider world displacing earlier forms such as Neanderthal and Denisovans. Another name for it is The African Replacement Hypothesis. The Out-of-Africa theory was supported in the early 1990s by research on mitochondrial DNA studies. The fossils of early humans who lived between 2 and 6 million years ago come entirely from Africa. Scientists do not all agree, however, about how these species are related or which ones simply died out. In fact there is some evidence:

As recent scientific evidence shows, Africa may have suffered from a lack of water roughly 100,000 years ago. Since water is essential for human life, the absence of precipitation may have caused early humans to migrate to other parts of the world. Scientists found evidence which establishes that modern humans were separated into small, dispersed groups due to the droughts. After the droughts ended, people decided to migrate to parts of Asia in order to ensure survival. The African people did not want to risk another drought, so they decided to begin emigrating out of Africa and exploring the rest of the world. The water deficiency in Africa may have caused modern humans to migrate out of Africa and begin inhabiting other regions of the

People have stated that not every human being came from Africa. That statement is false life started in Africa and

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.

The early northern Africa dispersal occurred 130,000 –115,000 years ago, as a result of tropical Africa experiencing megadroughts, forcing humans towards the seashores for food and water. Certain groups attempted to cross over to other continents in search for viable living conditions, but many retreated or

Moreover, the Out of Africa theory started with William W. Howells in 1976 and his “Noah’s Ark Hypothesis”, which essentially suggests, “a single origin, with populations migrating outward and diverging biologically, essentially by genetic drift (477).” His theory was later largely modified by Christopher Stringer in the 1980’s to what is now known as the Out of Africa model. There were other individuals involved in developing this theory with Stringer.

The opportunity to take part in economics internationally is a path to an abundance of personal and national wealth, business drives the global economy and I want to be a part of that. The U.S. is the leading capitalist nation, promoting business and trade widely. We see how various groups prosper financially and how some struggle. In the land of the free and home of the brave we see African Americans, Haitian Americans, Latinos and other minority groups struggle as a whole to overcome income inequality in the U.S. I am a Haitian immigrant living America with a passionate interest for business. I firmly believe that the Black community in America would benefit from a business knowledge. The Haitian government does not provide many
