Human Origins, Evolution, And Diffusion

According to anthropologists the first human beings lived in Ethiopia, Africa around 2 million years ago for example: Lucy known as the oldest human found there. The most probable reason why the first human left Africa is because of the Ice Age. The cold made life so difficult to survive and somehow reduced in their population. They went through a land bridge, which existed to connect North America and Asia during the Ice Age.

Development of humans occurred on the continent of Africa. The book mentions “Their [Humans] confinement to Africa, along with abundant fossil evidence, indicates that the earliest stages of human evolution were also played out in Africa.” on page 36.

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.

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

Human beings are still very much evolving. According to recent studies, genetic changes in women over the years have decreased the age at which they birthed their first child. In one study the age decreased as much as four years from age 26 down to age 22 (Allen 2011). Another concurrent study looked at women’s physical appearance in correlation with the number of children they had. The resulting data revealed that, “stout, slightly plump” women had more children. Researchers found that these characteristics are passed on from mothers to their offspring and so forth (Harrell 2009). Therefore, as these traits are passed from generation to generation, the population grows and these characteristics become more prominent in the population. All of these findings confirm that the evolution of human beings is still very much an ongoing process.

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

Anthropologists are continuously exploring the far corners of the world in search of answers to how everything came to be and the process by which we as humans appeared on this planet. This is a difficult task and therefore, there are many branches of anthropology which strive to discern the pieces of the puzzle from different perspectives and approaches. Through the implementation of the scientific method, anthropologists have tested numerous hypotheses to create theories like the Theory of Evolution. First documented by Darwin, natural selection, the process by which a more fit individual survives and passes on their adaptive traits, has been discovered to play a crucial role in the evolution of

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.

Two theories explaining the origin of humans are popular today among evolutionists. The first theory, multiregional continuity model states, modern humans evolved from several different groups of hominids that interbred at some point at produce modern humans(Actionbioscience.org, 2017). Multiregional continuity contradicted the ‘out of Africa’ theory with the data and the evolutionary development within the homo-species and its culture use and fossil findings. The evolutionary development of the brain in hominins was associated with increasing social complexity and the development of what we know as culture. Culture can be believed as the accumulation of knowledge, rules and mental abilities that humans utilise in order to survive. Obtaining

Africa has many diverse groups of people. The Maasai, Tuareg, and Bambouti are all very diverse tribes of Africa. The Maasai and Tuareg tribes are pastoralists, and the Tuareg tribe wears blue headressings. Also, the Bambouti tribe has an average height of five feet. The first humans were believed to have originated in Africa, and migrated away. Scientists have found the first evidence of humankind in Africa, in fossils. They believe that that is where we originated from. During the Bantu migration, that lasted for 1,500 years, the Bantu were believed to have metal tools. Even though scientists don’t know why the Bantu migrated, they were believed to have metal tools. Having metal tools allowed them to do thing more efficiently, and made other

Homo sapiens were evolved in Africa, now worldwide and have been dated about 200,000 years ago to present. Home sapiens adapations to tropical environments (Institute of Human Origins 2008). Homo sapiens are bipedalism because they can walk on ground level. Homo sapiens spend large part of their day gathering plants and hunting or scavenging animals, and control over fire (Smithsonian Institution 2016). Homo sapiens interact with each other and with their surroundings in new and different ways. “Cultural behaviours they made specialized tools, exchanged resources over wide areas; and they created art, music, personal adornment, rituals, and a complex symbolic world” (Smithsonian Institution 2016).

During the early 19th century, scientists, archeologist and other scholars, speculated, studied and disagreed about the development of humans and our origins. Some experts theorized that humans are monogenism and developed into various varieties of species. Others argue that we

Human evolution is the process by which human beings developed on Earth from now-extinct primates. Scientists theorized that humans are descendants of the early primate that over time, evolved into modernized species due to adaptation to the changes in the surrounding environment.

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.

God had deposited great wealth in Sub Saharan Africa and its lands holds the largest amount of the world’s wealth and treasures. Africa produces and export 60 percent of the world’s mineral resources, and supplies the largest amount of world’s precious stones.
