The first Neanderthal fossils found in Europe, a fragmented child’s cranium in Belgium in 1830, and an adult cranium in Gibraltar, were not immediately recognized as a divergent kind of human. Only in 1856 after a partial skeleton was found in a cave in the Neander Valley in Germany it became clear that these fossils belonged to an extinct human and our closest evolutionary relative (Hublin and Pääbo, 2006). Since then, questions about their relationship with modern humans have been fiercely debated between anthropologists. But what attracts most interest from scientists and popular media is the possibility of hybridization between Neanderthals and modern humans if, in other words, they were a genetically different specie or a single specie capable of producing offspring.
The first morphological features that later would become typical of Neanderthals, the projecting middle part of the face and a depression at the back of the skull, have been observed in fossils found in Europe as old as 400,000 years (Stringer & Hublin, 1999). These fossils belonged to Homo heidelbergensis, which in one of the various evolutionary scenarios that ties Neanderthals and modern humans is considered the ancestor of both Homo neanderthalensis and Homo sapiens (Hubmlin, 2009).
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...

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.
A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.
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

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).
Scientists thought that interbreeding would be a logical assumption to the Neanderthal conundrum. Unfortunately, any evidence of DNA from Neanderthals mixed with human DNA is difficult to come by because their fossils are usually tarnished upon finding. That is until Svante Paabo, and his research team from the Max Planck Institute for Evolutionary Anthropology, came across the remains of twenty-four Neanderthals and forty early humans.* All of these fossils were nearly 40,000 years old and were from Germany, Russia, and Croatia. Nine of these fossils (four Neanderthal and five human)

The Neanderthals are one of most iconic ancestors in what we have learned about the past in human evolution. As our closet extinct relatives and that of archaic humans, the Neanderthals are often label as the quintessential caveman. However, despite being once label as the embodiment of primitive humans of limited capacities; evidence has shown us that isn’t the case. The Neanderthals in their prime were able to accomplish and develop what was needed for them to survive from the moment of their evolvement until their end of their extinct.
Even though Neanderthals had some physiological differences between humans, there are proves to say that Neanderthals had some characteristics that related them to humans, and they were really intelligent like
The evidence for human evolution begins with the australopithecines. All the australopithecines were bipedal and therefore possible hominines. In details of their teeth, jaws, and brain size, however, they modify enough among themselves to be divided into five species: Australopithecus anamensis, A. afarensis, A. africanus, A. robustus, and A. boisei. Genus Homo are also divided in five different spices: Homo erectus, H. habilis, H. sapiens, and H. sapiens sapiens.
