That may be a human "concept" but in effect the maths behind it had always been there. Its like saying gravity its always been there but it look humans to explain it and express it.

True I guess they could mate in the wild but they don't live in the same area but maybe one day....

Although after reading your post, I could certainly say that the English language isn't very natural. 🙂

That seems to be the rule with this puzzle - if you come up with a correct answer people will pretend you never posted it.

How about the chair, I think a natural state of rest would involve lying down, or standing, or on all fours, but sitting on elevation is a uniquely human invention, as far as I know.

Also I think a lot of industrial machinery, like maybe the steam engine. I can't imagine anything that involes heat rising to make energy or something like that. Maybe also wrenches and nuts and bolts.

Books in general.

The radio, although perhaps antennae are inspired by plants reaching for sunlight?

Computers?! can't seem to find the shape of PC anywhere in nature.

The crucifix? Can't see anything natural creating something so evil.
maybe spiderwebs but i think that is a real stretch.

Bottles seem to be a uniquely human creation.

Office buildings and corporations, gov't structures and institutions are also uniquely human and not found in nature.


Tell me if I'm wrong on any of those.
