I'm pretty sure the polar bears are left over from DHARMA who performed experimentss on at the hydra (the small island just off the main one). We know that 'bears' resided in the cages where Sawyer and Kate were held.
I missed season 3 but went back and caught up, it just gets better and better!! I really hope the writers know where they're going with it though, there are so many story threads to explain, I don't want to be let down at the end.
I can't figure how they're going to get back, but then I can't fugre out much with this show!
It is now known that the island shifts in time. In the distant past, the island would have been inhabited by Polar Bears (time of an ice age) so the Polar bear, which seems to disappear could be shifting in time from then. In could indeed have been a DHARMA timeshift experiment.
