Neanderthals are our closest extinct relatives in the human family tree. They lived in Europe and parts of Asia from about 200,000 to 30,000 years ago. While they looked a lot like us, Neanderthals were generally shorter and more muscular. They had distinct features like angled cheekbones, prominent brow ridges, and wide noses, which helped them survive the cold climates of the Ice Age.
Initially, Neanderthals were thought to be primitive and savage, but recent discoveries have changed that view. Like modern humans, they made tools, wore clothes, controlled fire, cared for their sick, and even buried their dead. They also had the Fox P2 gene, which is crucial for language, suggesting they could speak and perhaps even create art by painting or engraving on cave walls.
If Neanderthals were so advanced, why did they disappear? One theory is that humans, with more advanced tools and social structures, outcompeted them. Humans also domesticated wolves, becoming better hunters. As resources became scarce at the end of the Ice Age, humans may have had the upper hand, leading to Neanderthal extinction.
Other theories suggest natural disasters, climate change, or disease might have played a role. An intriguing idea is that Neanderthals didn’t completely vanish but instead interbred with humans. For about 5,000 years, Neanderthals and humans coexisted in Eurasia, leading to interbreeding. This is evident in our DNA today; people outside Africa have about 1.5 to 2.6 percent Neanderthal DNA. Researchers estimate that around 20% of the Neanderthal genome is still present in modern humans, indicating they never fully disappeared but became part of us.
Knowing we carry Neanderthal DNA, what does it mean for us? These genes can influence personality traits. Studies show that people with more Neanderthal DNA might be less social, showing more nervousness and anxiety. This aligns with the idea that Neanderthals were generally less social than humans.
So, if you ever feel a bit antisocial at a party, it might just be your Neanderthal heritage showing through!

**Sanitized Transcript:**
[Music] Neanderthals are our closest extinct human relatives. They lived in Eurasia from 200,000 to 30,000 years ago. Their appearance was similar to ours, though they were shorter and stockier, with angled cheekbones, prominent brow ridges, and wide noses. They were perfectly evolved to survive the harsh winters of the Ice Age.
Initial discoveries of Neanderthals portrayed them as savage cannibals, but new evidence has emerged that has improved the image of the Neanderthal people. Like us, they made tools, wore clothes, controlled fire, cared for their sick, and buried their dead. They also possessed the same variant of the Fox P2 gene that is essential for language, suggesting they probably spoke and perhaps even painted or engraved on the walls of caves.
So, if the Neanderthals were such an intelligent and well-adapted species, why did they go extinct? A popular theory is that humans wiped them out. We had more advanced tools and social systems, and humans also domesticated wolves, which made them superior hunters. Human dominance over scarce resources at the end of the Ice Age could have contributed to the Neanderthals’ extinction.
Alternatively, it could have been a natural disaster, climate change, or disease that led to their decline. Another emerging theory is that Neanderthals never actually went extinct but instead interbred with the larger human population. There was roughly a 5,000-year period during which both Neanderthals and humans lived in Eurasia together, leading to interbreeding between the two species. The evidence is present in our DNA; in fact, about 1.5 to 2.6 percent of the DNA of anyone outside Africa is of Neanderthal origin. Researchers believe that 20% of the Neanderthal genome is still found within modern humans, meaning they never fully went extinct; instead, their DNA became part of the modern human genome.
Now that we know we have Neanderthal DNA in our genetic makeup, what can we do with this information? It turns out that these Neanderthal genes can affect personality traits. Psychologists have found that individuals with a higher level of Neanderthal genome may have an aversion to strangers and be more prone to nervousness and anxiety. Essentially, the more Neanderthal ancestry you have, the less social you may be. This aligns with the understanding that Neanderthals were generally less social than humans.
So, the next time you’re feeling antisocial at a gathering, consider whether it’s the environment or if it’s just a reflection of your Neanderthal heritage.
