Yes, humans living today have Neanderthal DNA. In 2010, researchers completed a study in which they sequenced the nuclear DNA of a Neanderthal, and compared it to the genomes of several present-day humans.
They found that Neanderthal DNA still makes up between 1-4% of the genomes of non-African humans, suggesting that humans and Neanderthals interbred at some point in history. This has been confirmed in more recent studies.
It is estimated that between 20-50% of the Neanderthal genome survives in the genomes of non-African humans today. In contrast, no Neanderthal DNA has been found in the genomes of people solely from sub-Saharan Africa.

Which people have the highest Neanderthal DNA?
Studies have indicated that East Asians and Europeans possess the highest levels of Neanderthal DNA. In particular, those of East Asian descent have the highest mean levels of Neanderthal DNA, with people of East and Central Asian descent possessing the most amount of Neanderthal DNA on average.
This is likely due to the close evolutionary relationship between the Homo sapiens that migrated out of Africa during the Middle to Upper Paleolithic periods and the Neanderthals who were already living in Europe and Asia at the time of human migration.
It is believed that during the process of migration, humans and Neanderthals interbred with each other, explaining why people of European and Asian descent have higher levels of Neanderthal DNA.
Is it good to have Neanderthal DNA?
Yes, having Neanderthal DNA can be considered to be beneficial because there are evidence to suggest that Neanderthal genes came through in humans that lived in Eurasia 40,000 to 80,000 years ago. Generally speaking, these genes have been linked to certain beneficial traits that have contributed to the success of modern humans.
For example, having Neanderthal genes is associated with better immune system responses. This means that modern humans with Neanderthal genes might be better at fighting off diseases than others without these genes.
Additionally, these genetic traits have been linked with an increased lifespan and promotion of better cognitive abilities.
However, there are still some risks associated with having Neanderthal genes. For instance, there is evidence linking Neanderthal DNA with increased risk of developing certain diseases like lupus, type 2 diabetes, depression, and stroke.
Additionally, in some cases smaller brain volume can also be linked with having Neanderthal genes.
Overall, it’s good to have Neanderthal DNA because it can provide certain beneficial traits that have been shown to enhance modern humans. However, it’s important to be aware of potential risks in order to make the most of these genetic benefits.
What is the benefit of Neanderthal DNA?
The benefit of Neanderthal DNA is that it can offer valuable insights into our evolutionary history as well as potential medical benefits. Because Neanderthals were our closest extinct relatives, understanding their genetic heritage and how it interplays with our own could help us understand more about our own genetics.
For example, research into Neanderthal genes has identified certain genes that we no longer carry but may have been beneficial in the past, helping us gain a better understanding of how the human genome has evolved over time.
In terms of medical benefits, studies have suggested that some Neanderthal gene variants may have positively influenced our immune response, metabolism, and even our behavior. For example, Neanderthal genes have been linked to better immunity to viral diseases and also to a higher level of risk-taking behavior.
Additionally, Neanderthal DNA may influence modern human health in even more nuanced ways, with one study finding that the number of Neanderthal variants we carry is linked to our responses to diets and medications.
All of these potential benefits offer us a greater understanding of our evolution and our own genetics, as well as provide possible medical benefits.
Are people with Neanderthal DNA more intelligent?
No, there is no evidence to suggest that people with Neanderthal DNA are more intelligent than those without Neanderthal DNA. In fact, research suggests that Neanderthal DNA might not have any effect on intelligence at all.
Studies have found that some genetic variants associated with Neanderthal DNA may be associated with increased risk for mental health conditions, such as schizophrenia, but that does not necessarily suggest higher overall intelligence.
An individual’s intelligence can be attributed to a variety of factors, such as genetics, educational experience, and environmental experiences, and there is no conclusive evidence to suggest that Neanderthal DNA has any significant effect on intelligence.
What diseases did we inherit from Neanderthals?
Recent genetic research has found that modern humans inherited some diseases from Neanderthals. For instance, humans may have inherited variants of several genes associated with type 2 diabetes, Crohn’s disease, lupus, biliary cirrhosis, and some forms of cancer from Neanderthals.
Some of the genetic variants present in modern humans appear to have originated from Neanderthals and to be more common in some populations than others. Neanderthal DNA may also influence certain immune responses and diseases, such as increased risk for respiratory diseases and increased immune responses to viral infections.
Other diseases that may have been inherited from Neanderthals include certain forms of blood clotting disorders, glaucoma, irritable bowel syndrome, and some forms of heart disease. Research suggests that Neanderthal introgression (the incorporation of genetic material from Neanderthals into the human genome) could explain the increased prevalence of several diseases in modern humans.
What color eyes did Neanderthal have?
Neanderthals are an extinct species of extinct humans who lived during the late Pleistocene epoch, from 400,000 years ago to 40,000 years ago. They are closely related to modern humans, and even interbred with them.
While much about Neanderthals remains unknown, scientists have made inferences about their physical characteristics, including eye color. It is believed that Neanderthals likely had dark eyes, similar to many people alive today.
Evidence suggests that nearly all Neanderthals were dark brown or black-eyed. However, some studies have suggested that they could also have had blue eyes, though this is not widely accepted. Additionally, a 2015 study found that Neanderthals likely had a gene that allowed them to produce the pigment needed for green and gray eyes, although it’s not known whether they had individuals with these eye colors.
Are there any Neanderthals alive today?
No, there are no Neanderthals alive today. Neanderthals were a species of archaic humans that lived in Europe and parts of Asia between 400,000 and 40,000 years ago. By around 24,000 years ago, they suddenly disappeared and became extinct.
Scientists believe that their decline was likely due to a combination of factors such as the spread of modern humans in their territories, climate change, and competition for resources. Despite their extinction, their genetic legacy lives on in many people today, as DNA analysis has shown that modern humans from certain areas of Europe and Asia contain around 2% Neanderthal DNA.
Do some Neanderthals still exist?
No, Neanderthals are an extinct species of human that were present in the Middle Paleolithic era about 300,000 to 30,000 years ago. They were an early branch of Homo sapiens, sharing many similarities with our species, but with some distinct evolutionary differences.
Many physical remains of Neanderthals have been found throughout Eurasia and in parts of the Middle East, but no modern day examples of the species exist today. Although Neanderthals were once the most successful form of human during the Paleolithic period, their extinction coincided with the ascendancy of Homo sapiens.
The exact cause for their disappearance is unknown, yet biological, climatic, and cultural factors are all thought to have been involved. Despite their extinction, Neanderthals have left a lasting legacy in the form of genetic material which is present in the DNA of all non-African modern humans and continues to shape our evolution today.
Who was the last living Neanderthal?
The last known living Neanderthal is believed to have died out around 40,000 years ago in Europe. However, recent DNA evidence found in humans living today suggests that the Neanderthal gene may still have some influence.
This means that modern-day humans may have inherited some genetic material from Neanderthals. So, it is difficult to determine who was the last living Neanderthal definitively.
Do Neanderthals share DNA with humans?
Yes, Neanderthals share DNA with humans. The two species are actually more closely related than previously thought. In fact, a 2010 study found that around 1-4% of the DNA of non-African modern humans derives from Neanderthals.
The similarities between Neanderthals and present-day humans have been further supported by genetic analysis. According to researchers, when comparing the modern human genome to the previously sequenced Neanderthal genome, there is a 97.
5% similarity.
In more recent years, evidence of interbreeding between Neanderthals and modern humans has been found. In 2016, it was revealed that half then non-African population possesses a small inherited segment of Neanderthal RNA.
The increasing amount of evidence confirming that we share DNA with Neanderthals certainly makes them some of our closest family in terms of evolution.
What caused Neanderthals to go extinct?
It is difficult to pinpoint a single cause of Neanderthals going extinct or to determine if their extinction was the result of a gradual or sudden process. However, the most widely accepted cause of Neanderthals going extinct suggests that it was the result of a combination of multiple factors.
One of the leading theories suggests that Neanderthal populations began to decline due to an inability to compete with modern humans, who appeared in Eurasia around fifty thousand years ago. This is known as the replacement model, which suggests that the competition between modern humans and Neanderthals for resources and shelter caused the Neanderthals to ultimately disappear.
This competition for resources could have also been. linked to climate change in Africa and Eurasia, as it may have created conditions that made it difficult for the Neanderthals to adapt and survive.
The second theory suggests that Neanderthals interbred with modern humans and the Neanderthal gene pool was absorbed into the larger gene pool of the Homo sapiens species. This suggests that modern humans, who had a wider range of adaptability, were able to outlast the narrow range of adaptability that the Neanderthals had; ultimately leading to the Neanderthals becoming extinct.
In addition to these hypotheses, there are many other theories that experts have discussed in relation to Neanderthals going extinct such as a high rate of inbreeding, limited technology and tools, or disease.
However, the combination of the two most accepted theories of competition with modern humans, and interbreeding with modern humans, are generally agreed upon as being the the main causes of Neanderthal extinction.
Could Neanderthals and humans coexist?
Based on the evidence gathered by scientists and archeologists studying the Neanderthals, it appears that humans and Neanderthals could have coexisted. Fossil evidence suggests that Neanderthals and humans co-existed in some parts of Europe, the Middle East, and Central Asia between 100,000 and 40,000 years ago.
Studies of Neanderthal DNA also indicate that some interbreeding with modern humans occurred, meaning that humans and Neanderthals interacted at some level.
Furthermore, it is believed that shared cultural activity and cultural elements, such as tools, may have been exchanged. Surprisingly Neanderthal technology has been found that was similar to that made by humans, in some cases even more advanced such as their use of fire.
Additionally, evidence suggests that Neanderthals took care of injured individuals and may have engaged in ritual burials and mortuary practices, which show that a certain level of complex behavior and the capabilities of interactive communication existed between them and humans.
With this evidence, it is clear that Neanderthals and humans lived in the same regions and that some level of interaction was present between the two species. Although it is impossible to tell how they interacted in detail, it is likely that Neanderthals and humans could have coexisted, even if it would have been in a limited capacity.
