Oh, that's not very helpful..

> we do not know if dolphins indeed label things in their natural communication system

I believe we'd need to start with that as a basic assumption for how language works to begin with. How does that assumption seem to you?

> dolphins appeared to be using signature whistles of dolphins who died some time ago

I guess they probably talk about loved ones even when they're not in the same "room", same as us.

> Signature whistles are tricky

"Signature whistle" seems like an awfully complicated way to say "name".
