How did animals adapt to the ice age?

How did mammals survive the Ice Age? As the Ice Age approached 1.6 million years ago, the climate became colder and many mammals grew larger. This is because large animals retain their body heat better than small ones. Heat retention was helped by growing thick, furry coats, such as that seen in the woolly mammoth.
