The Other Humans

🦴

The Neanderthals

Among them were the Neanderthals. They lived across parts of Europe and western Asia for hundreds of thousands of years. They survived ice ages. They hunted. They made tools. They used fire. They cared for members of their group. They adapted to a world that was often cold, difficult, and dangerous.

For a long time, popular imagination portrayed them as crude and almost human — but not quite. That picture has changed. The more we discover, the more complicated the story becomes.

Not Failed Versions of Us

Neanderthals were not simply primitive versions of us. They had their own evolutionary history. Their bodies were adapted to their environments. Their minds developed within their own social worlds.

They were not failed Homo sapiens. They were Neanderthals.

The Denisovans

And then there were the Denisovans. For a long time, almost nothing was known about them. Much of their story has been reconstructed not from complete skeletons, but from fragments and DNA. A finger bone. A tooth. Genetic material preserved for thousands of years.

The traces of a people who once lived, moved, and interacted with the world — and then disappeared as a distinct population.

Branches That Met

But the story does not end with disappearance. Because some of these branches met. When ancestors of modern Homo sapiens encountered Neanderthals, they sometimes had children together. Denisovan populations also contributed genetic material to some modern human populations.

The branches had separated. And then, in the vast movement of human history, some of them met again.

🧬

They Remain in Us

So the human family tree is not always a tree with branches that simply split and disappear. Sometimes the branches touch. Sometimes they cross. And sometimes, a little of one branch continues inside another.

Many people alive today carry traces of Neanderthal ancestry. Some populations also carry Denisovan ancestry. The people themselves are gone as distinct populations. But parts of their genetic history remain — in us.

The Human Family Was Larger

This changes the way we might think about the past. The story is no longer: "They disappeared. We survived." It becomes something more complicated. Some disappeared. Some merged. Some left descendants. And some of their history continues in the only surviving human species — us.

But perhaps the most interesting question is not only what these other humans could do. It is what their existence means for our idea of being human.

No Guarantee

Today, the word human appears to describe one living species. But for much of our evolutionary history, the human family was larger. Some may have lived in landscapes our ancestors had never seen. Some may have looked different. Some may have had their own traditions and ways of understanding the world.

We cannot know exactly what their inner lives were like. But they were not merely shadows on the way to becoming us. They were living people with their own histories. And for a time, the world contained many human possibilities.

Not Shadows

Then, gradually, those possibilities narrowed. One branch remained. The others disappeared as distinct populations.

Perhaps that is why the human mind can sometimes make us feel as though we are the centre of the story. We are the only humans left. So we look backwards and imagine that everything was leading towards us.

But the past tells a different story. There was no guarantee that Homo sapiens would survive. There was no evolutionary promise that we would be the last humans standing. For a very long time, we were simply one population among several. One branch among many.

Human Was Not Singular

And perhaps, somewhere in the distant past, another human species might have looked at our ancestors and wondered about them.

The story of humanity is not the story of one kind of human becoming more and more successful. It is the story of a much larger family. A family that lived, moved, adapted, met, mixed, and disappeared.

The other humans are gone. But they are not entirely absent. A little of their story remains. In the genes we carry. In the questions we ask. And in the ancient family tree that still leads back to them.

For most of human history, "human" was not a singular word.
