Fun Fact of the Day: Whales Evolved From Small Four-Legged Land Animals.



Whales used to walk land, just like us! In fact, they were small quadrupeds about the size of dogs. Evolution is a fascinating thing. These animals evolved out of the ocean… and then returned to it. This group of animals now contains the species (blue whale) that is the largest animal ever to roam the Earth.

There are still remnants of the whale’s time on land. For instance, whale embryos have the four limbs associated with terrestrial quadrupeds.

Like I said in my last Fun Fact of the Day post, I would love to hear your favorite fun facts about the natural world (or anything that interests you), so feel free to comment anything you know!
