Last winter olympics there were three kinds of skiers in the cross country ~ Laps(Sa'ami), Norse, and Others.
One of the "Others", a German guy, kept up pretty well with the Sa'ami until he overheated toward the end. They crushed him.
I watched guys going UPHILL 55 MPH in that race ~ at the end.
That's how humans were able to hunt the Arctic/subarctic regions' fastest animal ~ the Reindeer.
They could ski up hill, then come downhill at the animals MUCH faster than they could escape. You do that for a few hundred years and you can undercut the biological support system for the big cats, bears and wolves.
Renee Zellweger is part lap/Saami.
