The rat looking thing (Pakicetus) at the top of the picture is what a Blue Whale used to look like about 50 million years ago. It's classified as an amphibian, but it's basically a water rat that spent most time on land and some time in the shallow water.

There's a Blue Whale at the bottom of the picture and the Pakicetus at the proper scale just above it. It evolved to become about 17 times larger (1.5m long to 25m+ long).

For comparison, 50 million years ago was about when primates first appeared.

What are some other crazy evolutions ?

Please learn the difference between amphibian and amphibious

No. But it should say amphibious cetacean instead of amphibian

wikipedia doesn't dictate truth, nobody is saying that. But they do usually reference decent sources, that's where the truth is coming from. Wikipedia is simply aggregating and summarising the information so it's easy to read and share
