Humans have come a long way in evolution since cavemen roamed the earth in the Stone Age but what would happen if we never stop evolving?
One eerie simulation has shown exactly what that would look like if the human race continued the evolution process for the next 10,000 years.
In a video uploaded to the What If channel on YouTube, it explained that it has taken roughly six million years for humans to get to where we are today, and modern humans ‘have only been around for about 12,000 of those years’.
In the video, it explains: “We’ve become about 10 cm (4 in) taller, and now we can eat dairy foods after childhood.

“So if those things can happen in 12,000 years, where might we be hundreds of thousands of years into the future?”
The video continued: “Our future will be decided by the traits of people who have children, and how many children they have.
“If people who are naturally overweight and have health problems are the only ones having kids over the next million years, then that's how the human race will end up.
“But, we might not need to worry about any of these natural occurrences. Instead, we could become completely fused with technology before any of this happens. Cybernetic arms, brain chips, and laser eyes could all become possibilities.
“Not only that, but we also might be able to alter a baby's genes before they're born, completely getting rid of evolution altogether.”
If human evolution continues over the next 10,000 humans might end up having smaller jaws and teeth.
We’ll also likely have smaller brains with increased efficiency.
Some evolution simulations have suggested that it is our reliance on technology that could lead to thicker skulls and smaller brains.
Other possible traits include stronger immune systems and adaptations to climate change, such as thinner skin or larger ears for heat dissipation.
However, it’s difficult to predict exactly how humans will change and evolve over long time periods as it will be dependent on many factors including environmental.
Many people took to the YouTube comment section to share their own reactions to the simulation.
One user wrote: “I suspect that with as much pollution as we live in, our bodies might evolve to deal with it. I remember reading about a fish that evolved to survive in a river that was carcinogenic.”
Another said: “I feel like our bodies are probably devolving at this point.”
And a third person added: “Bold of you to assume we'll be around for another 10 thousand years.”
