> Aren't humans themselves essentially human made?

Humans evolved, but yeah the definition can be a bit hard to understand since it is hard to separate things. That is why I brought up the artificial insemination example since it deals with this.

> Maybe a better definition would be non-human (or inorganic if we want to include intelligence like e.g. dolphins)?

We also have artificial lakes, they are inorganic but human made.
