origin of modern humans: 1) they began in one place, Africa—and 2) pre-modern humans migrated from Africa to become modern humans in other parts of the world. According to the lectures, most evidence trace to the first theory because of a few satisfying valid reasons. In the lectures it was told that “fossils of modern humans are particularly found in Africa” (Zeanah: lecture). In addition to this logic, it is also mentioned that “DNA studies suggest a originating population in Africa” (Zeanah). Although
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
Africa the Home of Humanity 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
modern humans we think about two basic theories. The first theory is the “Multiregional Variation theory which is the different human populations or cultures had independent origins and are evolved in isolation from one another. The second theory is the “Out of Africa “theory. This theory is basically when humans evolved in Africa between 200,000 and 100,000 years ago. After these humans evolved they left Africa after evolving. Both of these theories both support and have evidence about human evolution
The modern day human has not existed for very long, in fact its one of the recent species to populate the Earth. Before modern day humans or Homo sapiens sapiens as we are scientifically known as, existed a similar yet less developed Homo genus named Homo erectus/ Homo ergaster. Evidence of these species dates back to over 1.9 million years ago and up to as recently as 70,000 years ago in which the evidence can be found in Africa, Europe and Asia. In this essay I will firstly provide a general timeline
Homo sapiens in Africa and the Middle East, Homo erectus inhabited Asia, and Homo neanderthalensis flourished throughout Europe. These species however, all lacked a cognitive flexibility which would destroy the blinding walls that blocked any connection between their multiple intelligences. All of science agrees that Homo erectus originated in Africa and expanded to Eurasia one million years ago. However, around 30,000 years ago, taxonomic diversity suddenly disappears and humans evolved into their
”Out of Africa Theory” 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. During the early 19th century, scientists
Africa played a pivotal role in human evolution. It’s the site of the beginning of human evolution, as they slowly evolved from their primitive ancestors and continued to evolve for millions of years. A majority of the fossils, some dating back almost 7 million years, are found in Africa. As ancient humans migrated out of Africa they stayed close to the coast. Scientists have been able to trace their migration to areas around the Indian Ocean, South Asia, and even as far down as Australia, also referred
origins of species. First species of Homo, Homo habilis, evolved in Africa around 2 million years ago. Later, a descendant of Homo habilis, Homo erectus evolved (along with other hominids), and spread out of Africa. Homo erectus gave rise to Homo sapiens around 100,000 to 200,000 years ago. One of the most controversial issues in paleoanthropology (the study of human origins) is about the origins of the modern humans or homo sapiens. The two theory’s in question are the “out of Africa” theory and the
Introduction: One fact that all anthropologists agree on is that H. Erectus evolved in Africa and during interglacial periods migrated to other parts of the world. What anthropologists cannot agree on is when H. Erectus became H. Sapiens. Paleoanthropologists know H. Erectus, H. Sapiens, and Neanderthals or Denisovans co-existed roughly 100,000 years ago during the Ice ages. Some species, not unlike Neanderthals or Denisovans, were able to adapt to the frigid temperatures of the Ice ages while others
