Not too long ago, our early human ancestors were under constant threat of attack from predators. And it turns out that this difficult chapter in our history may be responsible for the adaptations that allowed us to become so successful.

Throughout the first half of the 20th century, Neandertals were thought to have been…primitive. Unintelligent, hunched-over cavemen, for lack of a better word. But the discoveries made in that Iraqi cave provided some of the earliest...

Hank lays out three of the most awesome discoveries in science in 2013, from the fields of physics, space science and anthropology.

The nugget explains various evidences that favors organic evolution. Describe the importance of tracing evolutionary relationships.

A video explaining how embryology, anatomy, and genetics can be used as evidence for evolution.

Experts now agree that Africa was the birthplace of humankind. Many of the oldest fossils have been discovered in Africa. Climatic changes and the Ice Age, which began close to three million years ago, gave rise to the spread of our...

Only in the last 570 million years have life forms that we are familiar with started to evolve. Much of what we know about evolution comes from the fossil record. The first mammals started appearing about 220 million years ago, and only...

The ability to make and use fire has fundamentally changed the arc of our evolution. The bodies we have today were, in many ways, shaped by that time when we first tamed fire.

Discover how fossils help scientists to piece together evolutionary changes in early man - and how one very special fossil in Africa led historians down an exciting new path. Biology - Adaptation And Evolution - Learning Points. Fossils...
