The Evolution of Whales

I really have a thing for whales, which flies smack in the face of my dreadful fear of the ocean. The awe-inspiring vastness of the ocean is, I think, only matched by the awe-inspiring strangeness of whales. They are mammals, they live in water, they have a blow hole, they are huge (most of them), and they are remarkably intelligent.

But what amazes me the most is how they became what they became. A creature like this that started on land, and ended up being so well adapted to live in a salty ocean.

Below I’ve posted some pictures from Wikipedia that chronicle the evolution of the Whale, from land creature to sea monster.
