Welcome. As you can read on Nostratica's Home page:
This moderated newsgroup is a relocation of the original unmoderated
Nostratic list. In addition to discussing matters of reconstructing
the Nostratic Proto-language and the historical languages of the
Nostratic macrofamily, Nostratica will cross disciplines and culturel
boundaries and explore similarities between origins of language and
origins of species.
I will post several emails from the old Nostratic list in hopes that
we can continue our past discussions.
