Unanswered Questions About Human Evolution

Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning "wise man." Since at least the Upper Paleolithic era, some 40,000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from.

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.

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.

One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we will understand how we look today.

In the film Journey of Men: Genetic Odyssey anthropologist Spencer Wells proved that early humans migrated out of Africa. In order to prove that all humans share the same family history, this essay will first talk about where humans evolved from, the first humans in Africa, their DNA and chromosomes, and the migration itself.

Question #3: Why are non-human primates studied for how their behaviors related to our own origins? What types of studies are conducted and have these studies changed in recent years? Why or why not?

Human evolution is the process that led to emergence of modern human. The topic focuses on the evolution of primates especially the genus homo, and the emergence of humans as a distinct species of the great apes. The study of human evolution includes physical anthropology, primatology, archaeology, paleontology, ethology, linguistics, evolutionary psychology, embryology and Genetics.

2) The concept of descent with modification, or evolution, has a great deal of evidence in its support. Indicate the major types of evidence.

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

Studies have proven that humans are still evolving in many different ways. Selection pressure is what drives our bodies to evolve. Currently though, our bodies rely more on medicine than the natural drive that forces our body to evolve. An

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 central purpose of this essay is to critically discuss the importance of understanding human evolution and the history of psychology for the modern psychologist. For the human evolution, the essay will be addressing on how we and other species descended from our ancestors and how the different environment has helped to us to become more adaptable. Regarding the history of psychology, the essay will be discussing on how psychology branched off from the philosophy approach to become its own science. The essay will then go on discussing how the understanding of both human evolution and history of psychology would be used by modern psychologist.

The ‘out of Africa’ theory implies that Anatomically modern humans evolved in East Africa between 400,000 and 200,000 years ago and began to disperse throughout the world roughly 70,000 to 135,000 years ago. In 2011, scientists came to the conclusion there were likely two major waves of migration out of Africa - the Early northern Africa dispersal and Southern Route dispersal.

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.

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.
