This Is What Humans Will Look Like in 1,000 Years (2024)

FAQs

How will humans look like in 1000 years? ›

If left to natural selection, assuming we survive another 1000 years, we will probably look pretty much like we do now. A thousand years is an eyeblink in evolutionary terms. Just look at sculptures and drawing depicting people 1000 years ago.

(It also considered scenarios in between.) In 10,000 years, if we totally let it rip, the planet could ultimately be an astonishing 7 degrees Celsius warmer on average and feature seas 52 meters (170 feet) higher than they are now, the paper suggests.

In the year 3000, humans will exist in a world transformed by advanced technologies, AI, and robotics. They will possess enhanced physical and mental capabilities, coexisting and collaborating with intelligent machines.

We are now generally shorter, lighter and smaller boned than our ancestors were 100,000 years ago. The decrease has been gradual but has been most noticeable in the last 10,000 years. However, there has been some slight reversal to this trend in the last few centuries as the average height has started to increase.

Perhaps we will have longer arms and legs. In a colder, Ice-Age type climate, could we even become even chubbier, with insulating body hair, like our Neanderthal relatives?

Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.

By the year 3000, the warming range is 1.9°C to 5.6°C. While surface temperatures approach equilibrium relatively quickly, sea level continues to rise for many centuries.

Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.

Regardless, a lot can happen in 5,000 years. We might destroy ourselves with warfare or unwittingly ravage the planet with nanotechnology. Perhaps we'll fail to mitigate the threat posed by asteroid and comet collisions. We might even encounter an alien type II civilization long before we achieve that level ourselves.

In about 1 billion years, our planet will be too hot to maintain oceans on its surface to support life. That's a really long time away: an average human lifetime is about 73 years, so a billion is more than 13 million human lifetimes.

How Earth will look after 250 million years? ›

In about 250 million years, all of today's major land masses will pile together into one, just as they did about 300 million years ago to form Pangaea. And when they do, new simulations suggest, it could tip our planet's climate into an extremely hot state almost entirely uninhabitable for mammals.

According to his team's calculations, 250 million years from now, the continents will reunite and Earth will become unbearably hot, rendering much of the land uninhabitable and leading to mass land-mammal extinction. If the team is right, everything would be, as Farnsworth put it, “very bleak.”

Early humans were 5 feet tall on average

Height and weight have not consistently increased together; early Neanderthals tended to be taller than those who came later, but their weight remained the same. Their short, stocky bodies gave them an advantage in colder climates.

To fly! The dream of man and flightless bird alike. Virtually impossible. To even begin to evolve in that direction, our species would need to be subject to some sort of selective pressure that would favour the development of proto-wings, which we're not.

We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we'll be friendly and jolly, but maybe not that interesting. At least, that's one possible future.

A molecular biogerontology professor believes we've only started to move toward holding off aging, and that humans will eventually have the potential to live for 1,000 to 20,000 years. Technology not yet created would be key to extreme longevity, as we would need to be able to eliminate aging at the cellular level.

We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains.

Humans looked essentially the same as they do today 10,000 years ago, with minor differences in height and build due to differences in diet and lifestyle. But in the next 10 millennia, we may well have refined genetic 'editing' techniques to allow our children to all be born beautiful and healthy.
