What do you mean you've "considered evolution"?
The same as I have considered "cowboys had bowed legs in the 18th century because they rode horses." Bowed legs are also a symptom of rickets which was very common in Western America at that time. Ladies kept their "limbs" covered so we don't have sufficient information concerning the state of their appendages.
Darwin observed naked people who he believed were adapted to the cold in Tierra Del Fuego. He describes a scene of what in any culture is abject misery yet he concludes that they were adapted.
Now we know that they used fire and oiled their skin to keep warm. Also, was this actually the condition of the people before the clash of cultures? Were the naked folks merely very poor, displaced people who were clinging to the skirts of the empire, displaced, diseased and begging. What were the facts? What are the facts? Now the people there are no longer naked, enjoying the comforts of warm clothes and heating but supposedly that is because of long contact with Europeans.
So a person who has evolved to be comfortable in zero degree weather is perfectly comfortable in a big warm coat? That is saying that you, who are comfortable at 72, would snuggle up to a blast furnace and be comfortable at 120.
Or is evolution so amazingly fast that those people evolved into people who enjoy a normal temperature range in the space of 200 years?
Darwin saw naked people and created a theory. Most people would see naked people and give them a cloak for warmth.
Darwin's facts are subject to entirely different interpretations
