Most importantly, beaver dam is not an intelligence (and I doubt that it will wipe out its own creators) :) I was referring to one and I think the guy above me also did.

It's artificial, because it was crafted deliberately and purposefully to fulfill a need or want. Beavers weren't.

In that case, many human children are artificial.

No, human children resulted from organic processes beyond the control of the individuals who set the cogs in motion, so to speak.

As someone who needed donor sperm and a doctor to conceive, my kids are at least as artificial as a beaver dam.
