Re: Fwd: Linguistic studies have shallow time-depth; climate Change

First, your article deals with genetics and
archeology, not linguistics.
Second, linguistics and genetics don't always go hand
in hand. Genetics can show trends, substrates but is
not a smoking gun.
To give an example --all Celtic languages are now
found in the British Isles and Brittany, yet the first
Celtic culture we know of were in and around
Switzerland, Austria and S. Germany. Genetically,
Celtic speakers carry the genes of their non-Celtic
speaking ancestors.
Another example are Turks. The Turks spread out from
an area near Mongolia and left a trail from NE Siberia
to the Aegean, yet the farther you go from their
homeland, the less they genetically resemble the
original Turks.
Third, linguistics has a very long way to go before it
reaches the time depths in the article.
