The Inuit have evolved physically cope with the extreme cold of Northern Canada and Greenland.
The Inuit lived in Greenland one major settlement in Greenland that has a lot of Inuit is Sisimiut. Greenland has some of the harshest weather in the world with daily averages reaching as low as 3°F in March, with only 4 hours of sunlight. On top of that there is +80% cloud cover all year, though it is very cold there is not as much precipitation as you would expect.
In your femur there are 3 main parts the femoral head, the femoral neck and the shaft of the femur. The femoral head is the part that connects to the acetabulum (pelvis socket) in the pelvis. The shaft of the femur is the bone that runs from the hip to the knee what we generally consider the femur. Finally the femoral neck is the part of the bone that connects the shaft to the femoral head.

(2013) of over 8000 femora from over 100 different ethnicities, concluded that the femoral neck-shaft angle (NSA) is an adaptation to warmer and colder climates. Now you may be axing why this is such a helpful adaptation, it is because makes for a stockier build which follows suit with the fact that the Neanderthal’s build was much stockier that of the primitive Homo sapiens. Due to the Neanderthals movement towards more European climates rather than the primitive Homo sapiens’ moderate climates. This follows a pattern known as Allen’s rule, named after Joel Asaph Allen, stated in the late 19th century, it states that, the surface area of appendages of endotherms differs by climate, hotter the climate is more surface area, the colder the less surface area. In the case of the Inuit a small surface area would be preferable, so a narrower angle NSA would result in more body heat kept inside of the body instead of being transferred through skin-to-air contact. The Inuit ranked the lowest with the lowest NSA a mean of 120.2ᵒ with minimal SD (standard
