Why do polar bears live in the north pole and penguins in the south pole?
This is actually quite an interesting question. Polar bears are descended from continental bears that lived further south, over time they evolved their white coats and other characteristic to live on the sea ice. Bears can live in the arctic because the arctic has a lot of seasonal ice. the bears can go out on the ice, which isnt very thick, and capture seals that come to the surface to breath. Because the Antarctic is not connected to the continents, there was no way for ancient bears to migrate there. Penguins can live in antarctica for exactly the opposite reason. There are no bears! And no foxes or other land predators. None of the ancient ancestors of todays land mammals could get there. So penguins were able to swim there, and set up their colonies…. maybe they flew and afterwards evolved to have no wings – or rather, to have wings that were too small to allow them to fly. They don’t need to fly because there are no predators to catch them. In the Arctic there are birds very si
