For Anthropologists, H. sapiens and H. neanderthalensis are two of the most studied hominoid species. Yet, between them, there remains an anomaly. For hundreds of thousands of years, each species lived together in harmony, both consuming the same foods and using relatively similar technology. However, beginning about 15,000 years prior to H. neanderthalensis’s extinction at 30,000 BCE, archaeological evidence shows H. sapiens beginning to use more advanced tools and technology. During this period, H. sapiens began to develop more advanced hunting tools, more advanced shelters, and more complex art forms then H. neanderthalensis. To hunt for animals, H. neanderthalensis and H. sapiens had originally both used knives, points, scrapers, borers, and saws from flint flakes. However, at about 45,000 BCE, H. sapiens began to develop much more advanced technologies to hunt, such as bone, horn, wood and ivory fish hooks, as well as harpoons, eyed needles, and spear-throwers. These two species lived in conjunction for about 190,000 years- yet, during the last 15,000 years of their coexistence, H. sapiens suddenly developed more advanced hunting tools. …show more content…
To protect from the cold climates of Europe, H. neanderthalensis developed shelters made of animal skins stretched over bones or sticks. Yet, beginning at the Mesolithic era at 45,000 BCE; 15,000 years prior to H. neanderthalensis’s extinction, H. sapiens furthered the complexity of these designs. Shelters were constructed with floors of hard limestone plaster, wooden supports, skin or thatch covers, and hearths made from limestone blocks. Once again, despite the coexistence of these two species for about 190,000 years, H. sapiens suddenly began to develop more advanced shelters in the last 15,000
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.
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.
Humans are not the only species with the ability of making tools. Early on in her research, Jane Goodall observed an older male chimp, she called him David Greybeard. Through her observation of David, she witnessed two forms of the use of tools. The first was the use of grass as a tool to extract termites from their mounds. The second was the making of a tool by stripping the leaves off a twig, modifying it for the same purpose. When Louis Leakey heard this, he wrote her “Now we must redefine tool, redefine man, or except chimpanzees as humans” (Goodall, 2002). There is a definite correlation between man and chimps in this respect. Human culture involves learned behaviors through observation, imitation and practice, the use of tools with chimpanzees show the same ability for learned beh...
All of us have tools to make life easier. For example your cell phone is a tool that you use to communicate with. Paleolithic tools differed from Neolithic tools. The Paleolithic tool kit shown in document one was made for hunting.
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.
In his lecture, primatologist Robert Sapolsky explains the uniqueness of humans as well as our similarities to other primates. In doing so, he broke it down into six points of interest: aggression, theory of mind, the golden rule, empathy, pleasure in anticipation and gratification postponement, and lastly, culture. Professor Sapolsky approaches each point with interesting fact-based examples thus allowing me to gain insight on humans and other primates. Sapolsky’s knowledge of primates along with his scientific background allows him to make a clear argument that one cannot simply ignore.
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 the possible “extinction through absorption” theory which claims the Neanderthal interbred with the Homo sapiens and became one species. In this paper I will also be comparing the technologies, and diets of both species. In addition, I will look at the anatomic relation between the Neanderthals and Homo sapiens, how their body shape and size differed, and if this gave any advantage to one side or the other. My thesis for this paper will state that Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal in Eurasia is due to the appearance of the more culturally advanced and genetically superior Homo sapiens and the failure of the Neanderthal to adapt in an evolving climate.
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.
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 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.
There were two types of clothing made by Neanderthals, which were simple clothing and complex clothing. The difference between simple and complex is that simple is not tailored and complex is tailored. Simple clothing had one layer and complex clothing had multiple layers. The clothing functioned as thermal insulation by trapping the air close to the skin surface (Gilligan 2007, 501). The bodies of Neanderthals were biologically adapted to the cold, but clothing warmed the body even more. The climate change killed animals, which were needed for food and clothing. Animals such as Mammoths, could not adapt to the warm weather quickly enough to survive Neanderthals highly depended on the Mammoths for food and clothing. The need for the Neanderthals to depend on the large and dangerous prey is because their metabolic rates require significantly more calories to survive than modern humans (Wong 2009, 37). When a food source dies, the Neanderthals needed to adapt and find a new food source to get the amount of calories needed. Along with the food dying, there has been an argument that Neanderthals may have died because of hypothermia. X-rays of Tyrolean Iceman revealed signs of frostbite on one of his toes – but resistance to frostbite is a prominent feature of biological cold adaptation (Gilligan 2007, 506). The use of shoes by Neanderthals was highly unlikely, which could cause frostbite because they
In the early nineteenth century, fossilized remains discovered in northern European caves near the cities of Dusseldorf, Germany and Engis, Belgium led to the classification of a new species of hominin; Homo neanderthalensis, which takes its name from the Neander Valley where some of the fossils were discovered. These findings have until recently sparked much debate over its place in the lineage of our common ancestors (Smithsonian). Using information from the current fossil record the graph below illustrates the most likely common ancestor of modern humans and Neanderthals to be Homo heidelbergensis, a species of hominin which lived between 300,000 and 600,000 y.a. Fossilized remains of this species have been found as far east as India’s Narmada Valley (Pearson). A split of ancestral human and Neanderthal populations around 370,000 y.a. suggests that our evolutionary lineage continued unabated
The increase in brain size may be related to changes in hominine behavior (See figure 3). The third major trend in hominine development is the gradual decrease in the size of the face and teeth. According to the Microsoft Encarta Encyclopedia ’98, the fossil evidence for direct ancestors of modern humans is divided into the category Australopithecus and Homo, and begins about 5 million years ago (See figure 1). Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents (See figure 2). Although many fossil bones and teeth have been found, the way of life of these creatures, and their evolutionary relationships to the living apes and humans, remain matters of active discussion among scientists.
The cultural innovations analyses presented here illustrate the presence of cumulative cultural evolution in the upper Paleolithic and portray how a steady rate of change continuous with that seen in later human history. This should serve to encourage interests in the internal process of evolution that may tend to produce a smooth curve, including the possible the autocatalytic effects of the increasing technological
