    The reverse of this is camels: they fitst evolved their adaptions to survive the cold, not the desert.

      That isn’t the reverse, it’s the same deal - adaptations to one place turn out to be beneficial in another. Also, the desert IS cold at night, no?

        Arctic deserts are also a thing (e.g. Iceland). The similarities tell the whole story:

        • Poor access to liquid water
        • Need to insulate body from temperature extremes, wind
        • Food sources are sporadically available at best
        • Need to minimize contact with ground or insulate feet

        This is not to suggest that polar bears are similarly adapted to the Sahara. Rather, it’s not a huge shift, but it’s still a change.
