Neanderthals and early Homo sapiens once coexisted for a period of time in the distant past during the late Pleistocene era (Benazzi et al. 2011), so there is speculation that they may have shared various similarities. Whether they occupied the same niche, or used and created tools that resembled equivalent shape and form, or whether both species lived in groups that paralleled in hierarchy and social behaviors are questions that many researchers have been trying to answer (Wynn and Coolidge 2008). At the same time, there have been discoveries that allow us to recognize the distinctions that set Neanderthals and Homo sapiens apart.
During the Pleistocene era, which began around 1.8 million years ago, the continents had shifted to the locations that they are in today (Zimmerman 2009). According to Polly (www.ucmp.berkeley.edu/), the Pleistocene was discovered to be comprised of biomes that were similar to the ones that are identified today. Various forms of flora and fauna began to arise in this era as well, such as pines, mosses, flowering plants, insects, birds and mammals. Further into the Upper Pleistocene, it is theorized that Neanderthals and Homo sapiens originated in Africa and diverged around 450,000 – 485,000 years ago (Ovchinnikov 2010).
It is suggested that Neanderthals traveled to areas in Europe, India, and Asia from parts of Africa. This detached hominid group diverged into Neanderthal man over thousands of years while residing in the northwest India-Afghanistan region (Weckler 1954). Homo neanderthalensis dispersed much earlier than our own species had, which continued to occupy Africa for quite some time and eventually became confined to this region because of barriers such as massive lakes and highly elevate...

Over the last few hundred years, more and more has been added to the world’s fossil collection, fossils from all over the world. New theories have been created and old theories have almost been proven about the evolution of man. For example, we have proof that different species of man existed with certain types of DNA sequences and instincts, some we may not have anymore, or some that other species did not have back then. Even though it is subjected to much debate, one of the most widely accepted theories however, is that Homo sapiens interbred with the slightly more primitive species of man, the Neanderthal.
Around 1.8 million years ago, two hominids were born, first the Homo Erectus and then the Neanderthals. Although the two very different humans. However, were they that different? Our ancestors were very versatile hominids. They lived in various places and lived in a variety of ways. The Homo Erectus and Neanderthals were all special in their ways. They had similarities and differences that set them apart. They had similarities, but in the same way, their differences helped them survive if they had not adapted to how they lived they would have lasted the same time that their ancestors have lived. The Neanderthals lived for an average lifespan 30 years. They had to have some mistake that decreased their lifespan because if the Homo Erectus had done the same, there’s a chance that we might not be here now. Their differences set the future that we live in today. These

Four hypotheses of how the bodies got there occupation, water transport, predation, and death trap were ruled out. A new hypothesis was formulated what if Homo naledi intentionally buried their dead? Although there is not enough evidence yet to confirm this, such behavior would be significant in that it would precede previous cases of the behavior in Neanderthals and humans. This would add to the argument that Homo naledi are of the genus Homo. After the examination of these fossils and extensive research, it was concluded that Homo naledi were a new species of the Homo genus.
How humans spread around the world is still one of the mysteries in the history of mankind. Mitochondrial DNA has been a crucial line of experimental evidence in developing the current understanding of our genetic history. It has shed significant light in determining the population patterns and human migrations around the world. Studies of mitochondrial DNA have provided new insights in the way humans spread around the globe throughout time. Studies have suggested two major routes from East Africa through which humans exited Africa and colonized the globe. An early route through the tropical coast of the Indian Ocean to southeast Asia and Australasia 60-75 thousand years ago (kya) (Macaulay et al, 2005: 1034), and followed by a dispersal via the Levant into Europe and North Africa 40-45 kya (Atkinson et al, 2008: 472), these routes are often referred as “Out of Africa” migration.
Neanderthals lived in Europe and Western Asia between 200,000 and 30,000 years ago. Fossil record shows that around 150,000 years ago (Bar-Yosef, 1998; Grün & Stringer, 2000) their range extended from Europe to Middle East and Asia spreading to Uzbekistan and Russia (Herrera et al., 2009). They were probably the only hominin group living in Europe and Western Asia for a long period of time until the arrival of modern humans. Their extinction is dated at around 30,000 ye...

In recent years, the Homo Neanderthalensis were viewed as “subhuman brutes”, but are now seen as a different species from our own (Balter 2001). The Neanderthals were a branch of the Homo genus that evolved in Eurasia at least 200,000 years ago (Fagan 2010). The first Neand...
The Neanderthals are an extinct species of human that lived in ice age Europe between 120,000-35,000 years ago. This species is known for their receding forehead and prominent brow ridges. We know this species as the uncivilized or unintelligent person or group. Neanderthals are often portrayed as “unintelligent cavemen in animal-skin clothing.” Scientists’ first thought the Neanderthals’ were subhuman, but that thought is beginning to change. The original name given to the Neanderthals when they were first discovered was ‘Homo Neanderthalensis’ and they were considered to be an ancestor to modern humans. “Forty-four years after this biased classification, Neanderthals were reclassified as a human subspecies Homo sapiens Neanderthalensis and
From the ancient bones of the Neanderthals, scientists have been able to extract small amounts of DNA. The DNA comparisons to modern humans show no relationship, implying evolutionary separation (Kunzig, 159). Some anthropologists say the small sections of DNA found are not conclusive evidence, because modern humans show just as much variation in DNA. These people point out that individuals such as the “Portugal Kid” are hybrids of Neanderthals and modern humans, showing there was gene trading. One argument against this is that there is no skull from the ‘Portugal Kid” so it is hard to compare it to Neanderthals. Also, it is known that closely related species can breed and their offspring can be fertile, but they are still separate species (Kunzig, 161).
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.

The human archaeological record is a long and undefined story that may be the most complex question researched today. One of the big questions in human history is the disappearance of the Neanderthal people from the archaeological record around 30,000 BP. While for thousands of years Neanderthals and Anatomically modern humans crossed paths and perhaps lived in close relations, we have yet to really understand the degree to which they lived together. My hypothesis is that these two hominids, Neanderthals and Anatomically Modern Humans, interbred exchanging genes after Modern Humans dispersed from Africa and creating like cultures and material remains. The differences between Neanderthal and Modern humans are not only physical but also genetically evolved and this research will determine an estimated amount of admixture between the two groups.
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
