A language that requires the less amount of signs and symbols is the purest. These have different levels of impurity. The purest is the one which does not require a sign or a symbol. The purest language is the one we have in our minds when we think about something. We don't need to use symbols to ourselves because we know already what we mean.
The Proto-Human language (also Proto-Sapiens, Proto-World) is the speculative most recent common ancestor of all, or at least the large majority of, the world's languages. The concept of Proto-Human presupposes monogenesis (evolution from a common ancestor) of all natural languages apart from pidgins, creoles, and sign languages. It does not presuppose a common ancestor of these languages with all extinct lineages, whether human or possible Neanderthal languages.
