Blue whales are the biggest creatures ever. But how did they get so big?
Blue whales are the biggest creatures to have ever lived on Earth. Measuring up to a hundred feet long and 200 tons in weight, they have a heart the size of a small car. But how did they get so big? Surprisingly, whales weren’t always gargantuan water-dwelling mammals. In fact, their ancestor Pakicetus, was the size of dog and walked on land.
