Are Neanderthals really different from Homo sapiens?

The general perception of Neanderthals

What is the first word that comes to your mind when you hear the phrase Neanderthal? For many, the answer is primitive, brutal, uncivilized, unintelligible, dwelling in a cave, and somewhere among the barbaric (Peters & Zwart, p.2). They cannot belong to the same species as Homo sapiens! This was the dominant story about Neanderthals and Homo sapiens. Neanderthals lived and coexisted with Homo sapiens in Europe for hundreds of thousands of years up to about 40,000 ya (Peeters & Zwart, p.3). The Neanderthals were considered “human barbaric and barbaric races” by 19th-century anthropologists such as Hermann Schaffhausen (Glausiusz, 2020).

Negative attitudes of Neanderthals

This attitude towards Neanderthals has not changed much in the last century. A recent 20-year-old scientific analysis shows that Neanderthals are “strongly constructed archaic humans specializing in hunting and cleaning large and dangerous prey in cold habitats.” (Shipman, p.14241). These negative attitudes towards Neanderthals are quite puzzling, especially given that they are our closest relatives and the most famous races other than us (Peters and Zwart, p. 3). It is only recently that the story of the relationship between Neanderthals and Homo sapiens has begun to change.

Differences between Neanderthals and Homo sapiens

There are important and undeniable differences between Neanderthals and Homo sapiens. For starters, the Neanderthals evolved in Eurasia. Homo sapiens have evolved outside Africa. Neanderthals had a box-shaped, sturdy body with a protruding face, whereas modern humans have a flat front and a thin and delicate body (Glausiusz, 2020). The Neanderthals were hunter-gatherers. Homo sapiens rely on cultivation and domestication for survival.

While the Neanderthal diet was strictly composed of other animals’ meat, the Homo sapiens diet varied and consisted of fruits, nuts, plants, and heart. The Neanderthals mainly used stones as tools. Homo sapiens used a variety of stone tools in addition to bones, antlers, ivory, and other special tools (Glausiusz, 2020). Homo sapiens were superior in art, unlike the Neanderthals, who were “limited in technology, art, imagination, and the ability to create an overall culture” (Peeters and Zwart, p.12).

Several theories as to why the Neanderthals became extinct.

Perhaps the most important difference is the extinction of the Neanderthals and the survival of Homo sapiens. There are several theories as to why the Neanderthals became extinct. According to one theory, Neanderthals were few and expired due to their isolation from each other, adversely affecting their lines of communication (Engel, 2010). This meant that the Neanderthals were unaware of new inventions and technologies (Engel, 2010).

According to another theory, Neanderthals were so pleased with their skills and way of life that they became extinct because they had no reason to adapt to changes in their surroundings (Engel, 2010). They had a generalized adaptive approach that worked for them and supported them in all kinds of environments (Engel, 2010). However, it is important to note that while there are important differences between Neanderthals and Homo sapiens, it does not necessarily mean that they belong to different species.

Charles Darwin and Hybrid Charity

Charles Darwin, a British biologist, geologist, and naturalist known as the “Father of Evolution,” did not believe that the mating of two different species in 2019 would lead to the creation of new species (Forsdyke, 3, p. 1859). .. This is known as hybrid sterility, and is the inability of mixed species, which are descendants of 222 different species, to have their children (Darwin, XNUMX, p.XNUMX). The new species created by reproductive isolation was constructed by Darwin’s evolutionary natural selection to actively work when the organism survives and produces offspring (Forsdyke, 2019, p.3). Darwin felt that hybrid sterility “could not be obtained by continually maintaining a beneficial degree of sterility” because neither the hybrid species nor its parents had any advantage (Darwin). 1859, p. 222).

Darwin and other scientists view hybrid infertility.

Darwin’s view of hybrid infertility and how it is not adapted is accepted by today’s evolutionary biologists (Mallet, 2013, p.11). His claim that new species cannot be produced from reproductive isolation was fulfilled when his book was generally endorsed. Species Origin First published (Mallet, 2013, p.9). Biologist and anthropologist Thomas Henry Huxley said in a review of the book: The First and Infertility (Huxley, 1860, pp. 74-75) “(Mallet, 2013, pp. 9). But Darwin’s view is the origin of the species . For example, 20th-century evolutionist Ernst Mayr wrote in a 1963 book Animal Species and Evolution Darwin “has seriously attempted a rigorous analysis of the problem of species proliferation, the division of 1963 species into twelve. Never (Mayr, 2013, p.7) “(Mallet, 2013, p.7). Meyer, unlike Darwin, believed that new species would form when the species split (Mallet, XNUMX, p.XNUMX).

Causes of hybrid infertility

Darwin believed that the cause of hybrid infertility was “in the reproductive system of the predominantly mating species, either simply accidental or dependent on unknown differences” (Darwin, 1859, 235). page). According to him, the reproductive systems of members belonging to the same species are perfectly adapted to each other, but not the reproductive systems of members of different species (Darwin, 1859, p.249). The former cannot imagine, while the former can generally suppose. Hybrid species disrupted and impaired the reproductive system due to compounds of 1859 different species (Darwin, 249, p.XNUMX).

Modern research supports Darwin’s position.

Modern research supports Darwin’s position, except that he can identify the “unknown differences” that Darwin referred to. Today, it understands that chromosomal incompatibility is the reason for hybrid sterility (Johnson, 2008). Studies support this, as evolutionary geneticists have identified smaller and smaller regions of loci and chromosomes that do not work well together as some of the largest contributors to hybrid infertility in plants and animals (Johnson, 2008). ). George Mendel’s genetic discovery paved the way for all this information, especially the laws of segregation that stipulate that zygotes receive 2016 versions of a particular gene from each parent (Gayson, XNUMX).

Discovery, DNA, and genetics

Archaeological records are a very important concept in archaeology. This represents physical evidence of the past — artifacts, documents, photographic material, physical relics, and more (Bacon, 2010, p.1). The interpretation and documentation of these items by archaeologists, paleoanthropologists, and others provide a better understanding of people of the past (Bacon, 2010, p. 9). Thanks to archaeological records, in 2018, an ancient 2018 girl was discovered, a descendant of the 2018 Neanderthal mother and Denisovan father (Wei-Haas,). 2018). Multiple DNA samplings were performed on the bone fragments found in the Denisova Cave (Wei-Haas, XNUMX). Studies have also been conducted on mitochondrial and nuclear DNA in bone fragments (Wei-Haas, XNUMX).

As a result, she concludes to be a Neanderthal-Denisovan hybrid. This is a miraculous discovery, given that no one has ever found a direct descendant from this union (Wei-Haas, 2018). The mtDNA of a Neanderthal girl found in the Altai Cave in Siberia a few years ago also showed similarities to the DNA of individuals in Western Europe (Guimarães & Silva, p.94). The fact that Neanderthals and Homo sapiens mated with each other is important. In particular, new scientific studies have revealed that they mate more frequently than previously imagined (Glausiusz, 2020).

Discovery, DNA, and genetics continue.

According to anthropologist Israel Herschkovitz, “if 2020 organisms can reproduce and produce fertile offspring, they belong to the same species” (Glausiusz, 2020). If Neanderthals and Homosapiens belonged to different species, they would not have been able to breed offspring (Glausiusz, 2020). Some anthropologists reject this position and maintain the 2020 species are distinguishable from each other despite mating (Glausiusz, 2020). Biological anthropologist Shara Bailey said, “For all intents and purposes, they were separate species, but maintained their ability to hybridize” (Glausiusz, 2020). She claimed that their offspring were rare and could be bred but would not have been successful in breeding compared to their parents (Glausiusz, XNUMX). However, genetic records show that some hybrids were successful, and therefore Neanderthal DNA contributed to the modern human gene pool (Glausiusz, XNUMX).

Genetics and DNA linked between Neanderthals and Homo sapiens.

Genetics and DNA have recently linked Neanderthals with Homo sapiens. People consider that 1 to 4% of the modern non-African genome comprises Neanderthal DNA (Glausiusz, 2020). The Neanderthal DNA in modern humans is evidence that the Neanderthal genes are not completely extinct. Some scientists believe that the presence of Neanderthal DNA in modern humans is evidence that Homo sapiens did not defeat and exterminate Neanderthals, but instead, Neanderthals became Homo sapiens. It may absorb (Glausiusz, 2020). This is important because the Neanderthals were characterized as weak and inferior, as the Neanderthals were extinct and Homo sapiens were not extinct (Peeters and Zwart, p. 19). Currently, there is evidence that Neanderthals have not only crossed with Homo sapiens but are still alive in some of them.

Similarities between Neanderthals and Homo sapiens

Scientific research is also important to clarify the similarities between Neanderthals and Homo sapiens. A recent example of this is an international team led by Christopher Stringer, Clive Finlayson, Nick Burton, and Jolanda Fernandez Jeff. He grabbed 1,367 fossil specimens and hundreds of marine mollusk shells from Gibraltar’s Gorham and Vanguard caves. I excavated and analyzed it. (Shipman, p.14241). An analysis of the team of recovered fossil specimens and marine mollusk shells shows that the Neanderthals of Gibraltar utilized a wide range of terrestrial and marine resources, used small resources, and seasonally used those resources. Scientists in the late 19th century did not believe that Neanderthals could behave like modern humans, but their activities in Gibraltar have all the characteristics of current self-sufficient human behavior. There was (Shipman, p.14242).

Why Neanderthals Died, and We Survived

In his book Extinct Humans, author Clive Finlayson claims that Neanderthals Died, and We Survived Neanderthals have the same spirit and brain as Homo sapiens. It was comparable to Homo sapiens in power and cognitive ability (Peeters and Zwart, p.15). Neanderthals and Homo sapiens created tools, especially priming (Glausiusz, 2020). Some scholars speculate that the fierce competition between Neanderthals and Homo sapiens was the cause of the eventual departure of Neanderthals from the Levant to Europe (Glausiusz, 2020). Studies focusing on Neanderthal behavior have shown that their behavior is modern human behavior, especially concerning dental hygienists, large-scale co-hunting, complex stoneware, language, planning, illness care, imagination, and symbolic behavior. We clarify how the pattern reflects (Peeters and Zwart, p.2). We have more in common with Neanderthals than we think.

Humanization of Neanderthals

Although Homo sapiens technically consider Neanderthals human, “we are trying to keep a distance and use it to define our self-image. Often dull agility, brutal. It is based on a series of oppositions such as wise, conservative and innovative.” (Peeters & Smart, p.17). How often have you heard the word “Neanderthal” used to insult or insult yourself? Homo sapiens have nothing to do with Neanderthals and are susceptible to dehumanization.

Whatever the reason, Homo sapiens should not look down on Neanderthals. The Neanderthals may have become extinct, but they coexisted on an equal footing with Homo sapiens once upon a time. And they continue to live in many Homo sapiens today. It can not assert that the Neanderthals belonged to a different species than Homo sapiens. There is strong scientific evidence that Neanderthals are more closely related than not. Rather than staying away from Neanderthals, you can get better service by doing more research on Neanderthals and how they are and are not related to Homo sapiens. Increase. The more you learn about Neanderthals, the less likely you will dehumanize them.
