They relate this warm epysode to the expansion of early Arctic cultures in North America.

There are some things about Basque marrage practices I was wondering about, if you have the time the questions are in my comment at the relevant post-

Thanks in advance.
I've replied in the relevant topic, hopefully to your satisfaction. Thanks for commenting.
Yes, a very good response , unfortunately I didn't give your actual post the attention it deserved in posing the questions. If you go to "Polygenic bias in reproduction.... but how?" I have left a further comment speculating on its implications , any remarks you have will be very welcome.
