Did our most famous fossil ancestor, Lucy, die by falling out of a tall tree? The answer is part of a decades-long debate over how, exactly, our ancestors transitioned from life in the trees to life on the ground.

There were a huge number of croc-like animals that flourished during the Triassic Period. Dinosaurs had just arrived on the scene but it was these animals that truly ruled the Earth, becoming both abundant and diverse.

You might think that you’re pretty familiar with your body, but it turns out that our bodies still have some surprises for us!

2017 has been an eventful year, so as it comes to a close we'd like to look back at some of its most superlative science.

The Tyrannosaurus genus might have been more diverse than we thought. And researchers show how the composition of the early Earth could have accelerated its move towards habitability.

Fossilized footprints have proved that human ancestors were already striding across the landscape 3.6 million years ago. But who started them on that path? What species pioneered this style of locomotion? Who was the first to walk?

There is more than one type of bone in the human body. Anatomists usually consider 5 different types, based on structure and function. Histologically, we can even split them into 2, or more. In this video, you'll meet all the types of...

A baby is born with around 300 bones, whereas a grown adult has 206 bones. Cartilage, a rubber-like padding that shields the ends of long bones at the joints, is the reason behind this. Babies are born with more cartilage (than bone),...

In this video, we explore the screw-home mechanism of the knee joint that occurs near terminal knee extension in both open and closed-chain positions.

In this video, I explain and demonstrate the FABER test (Patrick’s test, Figure-4 test) of the hip. More specifically, we cover its rationale and interpretation of results.
