What If Neanderthals Never Disappeared?
Introduction
I recently read the book A Short History of the World in 50 Failures by Ben Gazur, and it really changed the way I think about history. Instead of focusing only on success, it explores moments of failure and how they shaped the world we live in today. One idea that stuck with me was about our “human cousins,” the Neanderthals—and it made me wonder: what if they didn’t completely disappear?
That question opens up a fascinating way to rethink human history, not as something inevitable, but as something that could have turned out very differently.
Who Were the Neanderthals?
Neanderthals were a species of early humans who lived in Europe and parts of Asia for hundreds of thousands of years. They were strong, well adapted to cold environments, and surprisingly intelligent. In fact, they made tools, created art, and may even have buried their dead—signs of complex thinking and culture.
Scientists like Chris Stringer (2016) suggest that Neanderthals were not primitive in the way people once thought. They were simply different from us.
Why Did They Disappear?
The disappearance of Neanderthals around 40,000 years ago is still a mystery, but researchers have identified several possible reasons.
First, there was competition with modern humans. When Homo sapiens migrated out of Africa, they brought more advanced tools and stronger social networks, which may have helped them survive better (Stringer, 2016).
Second, climate change likely played a role. Rapid environmental shifts may have disrupted Neanderthal habitats and food supplies. Studies in Paleoclimatology, including work by Jean-Jacques Hublin (2009), support this idea.
Third, small population sizes made Neanderthals vulnerable. Research from the Max Planck Institute for Evolutionary Anthropology (2010) shows that limited genetic diversity may have contributed to their decline.
But here’s the interesting part: they didn’t completely vanish. Genetic studies by Svante Pääbo and his team (2010) reveal that many modern humans still carry Neanderthal DNA. In a way, they are still part of us.
Fun Facts About Neanderthals
- Neanderthals had larger brains on average than modern humans.
- They may have had language abilities, thanks to genes linked to speech.
- Archaeologists found evidence of burials in places like Shanidar Cave.
- They created tools, jewelry, and possibly cave art.
- Some of your immune system today may come from Neanderthal genes!
What If Neanderthals Were Still Here?
This is the idea that really stuck with me after reading Gazur’s book.
If Neanderthals had survived, we might be living in a world with two human species. That alone raises huge questions. Would they have the same rights as us? Would they live alongside us, or separately?
Our understanding of science and evolution would be completely different. Imagine being able to study another human species that’s still alive—it would change everything we know about biology and the brain.
Physically, humans today might also look more diverse. Neanderthals were generally shorter and stronger than us, so our idea of what it means to be “human” could be much broader.
But not everything would be easy. History shows that humans often struggle with differences. There could be discrimination, conflict, or competition between species.

Final Thoughts
Neanderthals were not a “failure” in the simple sense. They survived for hundreds of thousands of years in harsh conditions. Their disappearance wasn’t caused by just one thing, but by a combination of competition, climate change, and biology.
And yet, they are not entirely gone. Part of them still lives in us.
Thinking about a world where Neanderthals survived makes one thing clear: human history is not as fixed as it seems. It’s full of possibilities—and sometimes, the biggest “failures” can lead to the most interesting questions.
