1. Most of Scandinavia as we now know it was covered with ice.
2. Only the North West coastline was icefree.
3. Sa'ami are the first known occupants of Sapmi (or Lappland). The Sa'mi are "European" ~ probably prototypically European, but they are different culturally, linguistically and to a degree genetically than the Indo-European people to their South who arrived several thousand years later.
Although it was supposed for a long time that the "vaguely Asian" look so many Sa'ami have implied an East Asian origin, the fact is that this is what Europeans looked like initially.
I know some Sa'ami descendants who are platinum blonds ~ with brothers and sisters with dark hair.
