The Roots Of The Tree

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

In the Article “Redrawing Humanity’s Family Tree” by John Noble Wilford, describes how two different skulls challenge the theories of human origins and migrations. The Central African skull, that dates back to nearly 7 million years ago, was assigned to a whole new genus and species because of its apelike and evolved hominid species. The 1.75-million-year-old Georgian skull shows evidence that the first hominids may have been intercontinental travelers who set motion the migrations that occupied the whole planet. Finally a third skull was found that is the same age and shares a resemblance but, the size of the skull suggests that the brain was smaller than expected for H. erectus.

On 4th August, 1914 our “Mother Country”, Great Britain declared war on Germany after the country invaded neutral Belgium. Australia, a country which is over 9000 miles away, almost instantaneously got in support of Britain. Within 6 months, over 52,000 Australians had enlisted to join the war; which is a mere 6% of Australia’s eligible fighting men in that time. Each of our Australian soldiers had their own motives. Whether it be: men looking to make money; brave, young men pursuing adventure; or the fear of being accused as a coward.

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.

Discoveries relating to the human lineage are extremely exciting and often baffling. This is the case with the recent discovery of what seems to be the oldest member of the human family. A skull found in northern Chad in 2001, has been deemed the earliest relative to the human ever found. Nicknamed Toumai, and discovered by Michel Brunet and his paleontology team, this new category of human has been given the scientific name, Sahelanthropus tchaensis. What makes this skull so definitive is the fact that it dates back approximately 6-7 million years in the earth’s history (Whitfield 2002). Since the discovery there have been anthropologists and paleontologists that have

For many years there has been a debate over where modern humans originated from. The first theory, out of Africa, discusses modern humans evolving in Africa. They migrated out to Eurasia and as the time went on their species evolved independently and developed into distinct species. All other human populations were eventually replaced with no interbreeding involved in the process and Homo sapiens had successfully dominated the rest of the world. On the other hand, the second theory, regional continuity, says that our earliest hominid ancestors had departed Africa and spread into other parts of the world later evolving into modern human beings. In this paper I will discuss the Regional continuity theory and elaborating on the Out of Africa theory. Evidence based on fossils, artifacts, and other crucial components will be discussed. Based on the evidence found I will come to a conclusion as to which theory I think best fits the origins of humans.

The early rush of volunteers and later the conscription of men led to a shortage of manpower on the home front. Women, already working in munitions factories were encouraged to take on jobs normally done by men.

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

It is generally accepted by scholars and scientists today that Africa is the original home of man. One of the most tragic misconceptions of historical thought has been the belief that Black Africa had no history before European colonization. Whites foster the image of Africa as a barbarous and savage continent torn by tribal warfare for centuries. It was a common assumption of nineteenth-century European and American Whites - promoted by the deliberate cultivation of pseudoscientific racism - that Africans were inferior to Whites and were devoid of any trace of civilization or culture.

The Out-Africa-Theory that has been heavily sided with is the hypothesis that remains the most likely to have happened. Not only because that is the theory that has the most scientific evidence but also because that is were the remains of the oldest primate fossil on all seven continents have been found. Even though the recent evidence in Asia is very convincing, there is too much noteworthy evidence found in Africa that an not be ignored. Moreover, such a new theory is lacking a substantial amount of evidence and investigation in order for it to become convincing theory. This leads the scientific world to side with the fact that we have deeper-rooted ancestry in Africa.

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.

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

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.”

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.
