“There were certainly settlers, but it’s dollars to doughnuts some of them went back home ~ with good news if nothing else.”
Where is home?
“They didn’t take women on a 4 year, potentially 8 year round trip journey ~ ‘cause babies arrive in 9 months. They took women on a 2 month trip in winter to stay.”
They sure did take them along. Everyone went. Look, I’m trying to explain why you can’t sled from Alaska to Greenland. It just doesn’t work, and they would have been killed by other native tribes.
“It is commonly the case that upper Neolithic peoples have a basic division of labor, and life.”
Neolithic? This is in 1000 AD or thereabouts. The Inuit are not neolithic people.
“The Iroquois carried this to the extreme of selecting new brides and husbands upon their return. No divorce in their system!”
The Iroquois are very, very different from the Inuit. Night and day. Why would Iroquois practices have anything to do with the Inuit?
“The first Eskimos into Greenland were on a long march ~ unting for things to eat, plus they may have heard from others of what could be found there. I can’t imagine why the men would abandon their familys in Summer.”
That’s because they brought them along for the trip.
Why don’t you go to google, and count the mountain ranges between northern Alaska and Greenland along the Arctic coast. It just isn’t feasible to dog sled.
The "other natives" are there anyway. Probably best to slip past them during the winter when they're holed up than in the Summer when they're out there grabbing stuff to store up for winter.
BTW, Neolithic is a level of cultural and tool development. You had people using Iron in some places, others still using bronze, and yet others deep into stone.
