Scientifically accurate frost giants
In my fictional world I am planning to have a humanoid species living on an arctic continent, and I am wondering what type of biological adaptations a humanoid (as in, anatomically modern humans or our extinct close relatives) might need to survive in such an environment.
For clarity, the continent in question is an ice-capped land mass connected to other, more temperate continents so there is no issue about migration into the region and the climate will most likely be more stable than our real-life arctic due to having proper ice caps rather than just sea ice. This question is purely about biology and the types of adaptations that my hypothetical humanoids would probably develop given enough time & isolation in this environment.
The inspiration is of course the jotunar found in Norse mythology, but my humanoids need not be actual giants. They should however be intelligent on some level, and have some capacity for speech and language if not the cultural sophistication of humans.
