Which is more natural, capitalism or socialism?

So, obviously, the concept themselves of capitalism and socialism as such only exist in human society. But which is more natural?

It seems like some rudimentary notion of property is common in the animal kingdom. For example, many animals will build structures and be posessive over said structures. There is even the concept of owning land for productive exploitation.

For socialism I guess you could point to social animals. Ants might be an example of socialism. Although ants are basically sterile slaves working for the state (accurate I guess?)

I'm not sure which is more natural, but capitalism mostly just needs the concept of property which isn't a high barrier. Socialism has many more criteria. So maybe capitalism is more natural.

What do you think?
