However, there are other theories that explain the disappearance of the Neanderthals. Our present morphology and behavior have greatly changed from archaic humans because of natural selection in a global human population.
Most helpful essay resource ever! Modern humans are taller and thinner than Neanderthal and have a well-defined chin, vertical forehead, and much smaller brow ridges Shreeve The recent origin explains why today's human populations are genetically similar -- they haven't had time to diverge very much.
African populations today are more genetically diverse than populations in other parts of the world. Over the years science has lead us to new discoveries, with the finding of fossils, ancient tools, and DNA Abouttoyears ago, while our ancestors were still in Africa, another hominid species known as Neanderthal was living in what is known today as modern Europe and the Near East.Humans today are quite different anatomically and behaviorally from archaic people that is, most humans before 40, years ago anywhere in the world. This is a logical assumption, due to many anatomical similarities between many of the early hominid species to modern humans. The sides agree on two different theories called the Out of Africa theory and the Multiregional or Candelabra theory. The first and primary theory states modern humans emerged in one place and from a single origin. They have especially uncovered many pieces to our still incomplete puzzle over the past 20 years so that we now have a nearly complete idea of how our species Homo sapiens came to be. Out of Africa Anthropologists today are debating two sides to the story of the evolution of the modern human Homosapian sapian. Some scientists believe in the hypothesis known as the Multiregional Theory. Mutations and the selection for these mutations must occur in order for a species to evolve. Anthropologists discussed the possibility of each group moving a small distance further than their direct ancestors, creating a slow move, often along coast lines, which unfortunately would leave little evidence on land Geographic, This theory is known as the Recent African Origin Model. These factors gave Africa a dominant role in the ancestry of today's human population. The essays in our library are intended to serve as content examples to inspire you as you write your own essay.
