Sequencing Of The Neanderthal ( Homo Neanderthalensis ) Genome

If Neanderthals did in fact comport themselves in ways once thought to distinguish anatomically modern humans and enable the latter’s rise to world domination, that similarity makes the Neanderthals’ decline and eventual extinction all the more mystifying. One theory is that H. sapiens had a broader variety of tools that may have enhanced their ability to forage. When they brought their superior technology with them out of Africa and into Eurasia, they were thus better able to exploit the environment more effectively than the resident Neanderthals could. Still, the arrival of H. sapiens did not equal an instant demise for Neanderthals. The latest attempt to track their decline, carried out by Thomas Higham of Oxford and his colleagues, applied

Neanderthals and modern humans became one species, through thousands of years of interbreeding. Supporters of this theory state that some modern day Europeans have facial features similar to Neanderthal man. Neanderthal genes may have been inserted into the human gene pool, and Human genes may have been added to the Neanderthals. At this point, Neanderthals and humans may have evolved together at an incredible rate, becoming one race in a relatively short period of time. On the other hand, a disease, a war, or an increase in population causing the natural resources to be inadequate for keeping so many hominids alive might have cut off Neanderthals suddenly from contact with the humans,

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, says that our earliest hominid ancestors had departed Africa and spread into other parts of the world later evolving into modern human beings. In this paper I will discuss the Regional continuity theory and elaborating on the Out of Africa theory. Evidence based on fossils, artifacts, and other crucial components will be discussed. Based on the evidence found I will come to a conclusion as to which theory I think best fits the origins of humans.

Traditionally, Neanderthals have been viewed as large, hulking ape like beings that survived by aggression and power through the harshest conditions possible on earth. They have been painted as unsophisticated and unable to compete with humans on an intellectual level. These academics theorized that superior human intellect and reasoning gave humans the advantage in hunting game and securing the most valuable natural resource, eventually driving the Homo neanderthalensis to extinction 30,000 years ago. Popular culture describes Neanderthals as first viewed by science as large, hulking ape like beings. However, new evidence suggests that one of the first reconstructed Neanderthal skeletons did not consider that the individual suffered from acute arthritis. Despite unique, this Neanderthal ‘s hunching posture was associated with the entire species, giving one the impression of a “brutish caveman”. This new understanding has reformed research on the Neanderthal and a new understanding of humanity’s earliest ancestor

The evidence that supports that Neanderthals inter-bred with Homo sapiens is that of a skeleton that was found of a young modern child. The skeleton was determined to be that of an early modern human child, but the skeleton had Neanderthal characteristics as well as modern human characteristics. It was determined that if this child had Neanderthal traits then Neanderthals were part of his ancestry. That would mean that Neanderthals inter-bred with Homo sapiens. Beyond that there has been DNA testing of bone fragments that suggest that even though Neanderthals were different from Homo sapiens they weren't so different that they could not breed with each other. Anatomically modern humans and Neanderthals were the same.

Neanderthals were human enough to intermix with Homo sapiens because of the genetic studies on modern day humans in the British Isles. A separate species cannot interbreed with another species and have offspring. Mules and horses can breed to have donkeys although donkeys are sterile. Humans of the British Isles have Neanderthal DNA also Devsonian DNA.

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

Evidence indicates Neanderthals and Modern humans shared a common African ancestor and split on the evolutionary tree between 500,000 to 200,000 years ago. Neanderthals developed in the cold and harsh environment of Europe and western Asia. With a lot of water locked up in the polar ice caps, Africa was experiencing a severe drought. This arid and dry environment is where modern human’s direct ancestor was living. These people’s bodies were a lot taller and weaker (to allow heat to escape) in comparison to the Neanderthals. This severe drought placed modern humans on the brink of extinction. However, when a species is dying out only the most inventive and resourceful survive, this causes the fitness of the remaining population to increase. In Europe the Neanderthals toughness allowed them to be very successful. In Africa the modern humans developed something the Neanderthals did not have, imagination. In Africa to survive it was necessary to think ahead and this allowed them to make the final step in becoming modern humans. Every previous human ancestor had been limited to the confines of their environment, but these ancestors eventually made their way out of Africa, and their imaginative behavior is illustrated in the drawings they left behind for others to find. After they left Africa they could have very well come into contact with the Neanderthals. Neanderthals became

Neanderthals and modern humans coexisted for well over 100,000 years.  Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.  Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.”  What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.

Neanderthals exhibit an extinct primate genealogy that existed in Eurasia for hundreds of thousands of years. They flourished in these territories for quite a while, however declined in numbers and vanished around 30,000 years ago. Curiously, their extinction happened following to the advent of modern humans into these territories, which has provoked some to contend that Neanderthals were uprooted by more qualified and more versatile modern humans. Still others have hypothesized that Neanderthals were absorbed into the gene pool of present modern humans by admixture. As of late, developments about the connections amongst Neanderthals and modern humans were based exclusively upon indications found in fossils and archaeological records.

Some scientists believe (Duarte et al., 1999) that Neanderthals and modern humans not only interbreed in Europe but Neanderthals are the biological and cultural evolutionary transition between archaic and early modern

As recently as only five years ago, anthropology researchers found that humans and Neanderthals had interbred at some point in time simply based on the shapes of skulls found in caves buried beneath thousands of years of soil. This mirrors a 2010 study that has uncovered the first proven

There is evidence to suggest that Homo neanderthalensis and Homo sapiens had coexisted for approximately 35-40,000 years, (Fagan 2010) from around 60,000 years ago to 25,000 years ago when they finally went extinct (Gibbon 2001). Anthropologists are still uncertain what the cause of their extinction was. This paper will analyze three main theories of Neanderthal extinction. The first theory is the competition theory, which claims that the Homo sapiens and Neanderthals had to compete for resources, ultimately leading to their demise. The second theory I will discuss is the climate change theory, which claims that Homo sapiens lived while Neanderthals died because they were better adapted to the climate. The last theory I will discuss is

Humans began their diaspora from Africa about 70,000 years ago (Newsreel.org, 2014). Since then, we have stretched to a variety of geographic locations in every corner of the world. A biological definition of race advances the idea populations within species have discernible characteristics compared to other populations, thus suggesting the presence of sub-species under Homo sapiens. This has been falsified by many scientists. Dr. Alan R. Templeton says “there are not enough genetic differences between groups of people to say that there are sub-lineages of humans” (Fitzpatrick, 2003). In fact, the genetic differences between individual humans are entirely small about 0.1% (Humanorigins.si.edu, 2014). Human populations have not been geographically barred nor isolated from one

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
