The message
from Terry Fields contains these words:

There is indeed a strong link between Solutrean artifacts and very
similar items in America and there is some mitochondrial DNA linkage
between several native American tribes and some modern European groups
but as with any hypothesis for which there is absolutely no evidence
there is some dispute about whether the the Solutreans ever made it from
Europe to America at all let alone whether they did it by land or sea.
Nor that they used kayaks.

In that case, the BBC TV programme that showed the DNA traces was a
load of rubbish.

Thanks for your input.

Not a program I ever remember watching but have you any evidence that
DNA relating to the Solutreans or native Americans of similar antiquity
has ever been extracted?

The BBC is good at turning supposition into concrete fact - vis walking
with dinosaurs.

As for alternative routes for DNA, the obvious one is a minor European
contamination of the largely Asian DNA of the Native Americans.
