Humans as Animals

Humans as animals. (Our true nature). That sort of thing. I'm not talking about anthropomorphism but of the idea of humans without technology.

Question: Is Language Technology?

If words are tools, surely the answer must be yes, in which case 'humans without technology' also lack language. In that case, are they truly human?

Looking at an individual, we might define them as human based on genetics, regardless of ability to speak or understand speech (or sign language). An alinguistic person is human because of their family connection. What about an isolated alinguistic group of people?

What about groups of language using 'animals' - dolphins? Gorillas etc. who have learned sign language? I think most would agree - not human, however deserving of 'rights'.

Thank you Keegan for suggesting this interesting topic :)
