Oh my god… I was going to make a “Sonic beating himself” joke but this is way better then anything I had in mind.

The Cocoanuts is pretty good though.
They were repeatedly being selected for the people who could handle a slightly colder environment, so by the time the population reached the polar regions, all that was left was people with traits to handle the cold. Any remotely beneficial recessive gene would quickly replace dominant alleles in the population.
Although I’m sure there was some genetic adaptation, I’d argue it was more technological advancement. The northernmost tribe discovers a better make of clothing, or a better housing structure and suddenly the colder winters farther north are now tolerable so people settle there. The new northern tribe refines their technology and knowledge and now that they know how to… ice fish or something they have a winter food source, and now their descendants can settle even farther north.
A bunch of creepy nerds e-stalking college girls and ranking how hot they are without their knowledge or consent? Or is that iteration considered a separate product now?
