The ancestors of gars, horseshoe crabs and coelacanths looked almost the same as their modern relatives. Darwin called species like these “living fossils'' because they seem like they are evolutionarily frozen in time. But Darwin was wrong.

Lizards are incredibly widespread and diverse but it took them a long time to get to where they are now. Because they used to face some pretty stiff competition from a group of lizard look-alikes.

What happens when a species is the only of its kind? This phenomenon is called a monospecific taxon. Studying these special species can help us better understand not just those sparse groups, but all life on this planet! Join Olivia...

Many cat owners are familiar with the "gifts" their feline friends are fond of giving, but if left unchecked, this behavior can be devastating.

When there’s only one species on an evolutionary branch, we call it a monospecific taxon. Studying these special species can help us better understand not just those sparse groups, but all life on this planet.

During the 2017 Project For Awesome livestream, I promised I'd make a tuatara video if we hit our fundraising goal, and I'm a man of my word! Little did I know I'd get to meet a tuatara and learn things about a 200 million year old...

Because there are so many different types of penises among our evolutionary relatives, we didn’t know until a recent discovery whether they all had the same origin.

Why did so many birds ditch penises? Maybe it was natural or sexual selection, an accident, or in exchange for something way more useful to them. Whatever the reason, penis loss goes to show that internal fertilization doesn’t require a...

Many cat owners are familiar with the "gifts" their feline friends are fond of giving, but if left unchecked, this behavior can be devastating.

Crocodiles, horseshoe crabs and tuatara are animals that have persisted for millions of years, said to have gone unchanged since the days of the dinosaurs. But even the most ancient-looking organisms show us that evolution is always at...

A perfect kids learning video about animals. What is a Zoo? A Zoo is a place where you can go and view animals from a safe distance. Many of the animals in the zoo are wild animals from all around the world. These zoos usually house...
