beginning of time and the beginning started in Africa. Anthropologists guess that we, Homo sapiens, come from other animals such as chimpanzees since they are our neighboring relative. Many other species arose in Africa as well and we all shared one thing and that was the ability to walk up on two legs. As time went on, our brains grew larger and we started migrating to other places such as Eurasia and started using tools. Ultimately, all of the species died out and we were the only ones left because of
Out of Africa vs. Multiregional Paleoanthropologists have been searching for decades, looking for signs of early human life throughout Africa Asia and Europe, trying to find clues that tell them where the human race originated. These scientists have found overwhelming evidence of early human life across different continents, but are always working to attempt to explain what they have discovered, and try to piece together the earliest signs of human civilization. Two main theories have emerged
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
Question of Our Origin: Two Opposing Theories During ancient archaic times, several species existed in the Old World including 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
our origins that can be traced to Africa and (Eur)Asia. African origin stresses the multiregional continuity theory it suggests a single origin for modern humans and gives an explanation to the Out-of-Africa model for the patter of our human evolution. The Multiregional Continuity Model states that after Homo erectus left Africa and spread into other parts of the Old World, regional populations gradually evolved into modern humans. In contrast, the Out of Africa Model states that modern humans evolved
Home Essay Origins to Our Existence on Earth There are two theories about the 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
human form through two largely known origin theories. The two theories that are widely discussed include, Out of Africa and multiregional evolution theory. Commonly, the way these theories are differentiated is through geography, time-scale, and process (Stringer 67). These different elements of distinguishing origin theories has led to many misinterpretations and controversies of the major theories. There have been fairly recent clarifications on each theory, which helped to properly progress evidence
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
Australopithecines, have resided in parts of Africa. We don’t see any movement out of Africa until the appearance of the Homo erectus fossils. These fossils have been found not only in Africa, but have also been found in parts of Europe and Asia. This is when scientists begin to disagree on how these pre-modern humans spread from Africa to other continents. Some scientists believe in the hypothesis known as the Multiregional Theory. This theory states that Homo erectus left Africa about two million years ago and
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 beginning in Africa. About
