How can penguins live in places as cold as Antarctica

Like whales, penguins have a thick
layer of fat (blubber) that protects them
from freezing temperatures. Their feathers
are stiff and tightly packed together. A special
structure near penguins’ tails produces
oil that coats their feathers and makes
them waterproof.

They adapt, just like how camels, snakes, lizards etc. Live in the desert. Also cuz of natural selection, theorized by charels Darwin.
