Ancient Civilization Human origins

In a cave in France, 176,000 years ago, a group of Neanderthals arranged large stones in circles. The meaning of this is a mystery, but they showed signs of being burned. This could have been for warmth, protection, or as a part of a ritual. This stone circle was found deep in a cave and shows that Neanderthals went underground and far from light. This discovery is sparking debate about the previous understanding of the intelligence of human predecessors. Listen to hear more about this discovery.

You've Got Face Mites

biology Human body Human origins

Tiny, 8-legged creatures are crawling all over your face. This isn’t a scene from a horror movie. This is a fact. We’ve all got mites on our face and we have probably had them since before we were human. Occasionally, face mites are linked with skin issues, but they are mostly harmless. By studying these microscopic creatures, scientists can learn a lot about evolution. These mites travel with us through generations and can help trace our origins. Listen to this story to hear more about what can be learned from studying face mites.

A New Human-like Species

Evolution Human origins

A new species that tells us something about humans origins was recently discovered deep inside a cave in South Africa. This discovery is a mystery in many ways. How did the bones get there? What is their significance? The bones are so deep inside the cave they were almost inaccessible; scientists had to climb down a steep cliff and crawl through a cave to collect them. This new species appears to have very small brains but similar feet and hands to modern humans. It has been named Homo naledi, the newest addition to the genus Homo. Where do they fit in the story of human evolution? Listen to hear more about this remarkable discovery.

The Epoch of Humans

Earth and Space Science Human Impacts Geology Human origins

When did humans begin to shape the earth? This is the debate happening among geologists who are determining whether the official timeline of the Earth should have a name for the current period of human domination. The concept of the “anthropocene” or the human era first emerged 15 years ago and a working group of scientists is determining whether to adopt it officially and when it should begin. Listen to learn more about the lively debate that surrounds this decision.
