Ancestral voices.

With vague memories of a telly prog I saw once stirring in my brain, I've been looking at proto-world language as a possible starting point for my new language. If you're not familiar with the concept, the proto-world languge hypothesis says that all languages evolved from a single ancestor language back in the mists of time, and that by looking at similarities between languages it might be possible to reconstruct this ancient tongue. I find the idea strangely moving.
