Nostratic family

Piotr:
I'm venezuelan and behind me there are some people gathered on Indoeuropean
studies, despite of we are not linguists. Fortunately I have found this and
I shall ask you many things to clarify our ideas.

Today's question is about Nostratic family. In short, what is the
fundamentals of this hypothesis? Was it a language family or rather a human
race? What are their daughters?

Kind regards
MR
