Hank brings us some late-breaking news from the genus Homo - a team of scientists has sequenced the genome of the Denisova hominin, the latest member to be added to the human family tree.

Detecting diseases early can be a big help when it comes to treating them, and researchers may have gotten one step closer to diagnosing Alzheimer's with a simple blood test.

Fossils can provide clues to the conditions that ancient species lived in, like what their environments felt like, how deep in the water some species lived, or even how long the Sun was out!

Hank gets to the bottom of an exciting, and kinda weird, announcement from Russian scientists at the Vostok Research Station in Antarctica. Have they reached a 20-million-year old underground lake? Maybe! Is there a hoard of Nazi secrets...

If you’re on the “paleo diet,” you’ve probably been avoiding wheat and potatoes, but a new study published last week indicates that humans have been eating starches for more than 100,000 years!

We don't need a time machine to learn from the past (but let us know if you find one)! Air bubbles trapped in ice for millennia and ancient pollen grains can tell us a lot about climate shifts hundreds of thousands of years ago!

Today, penguins are found mainly in the Southern Hemisphere. But fossils have revealed giant lookalikes to these swimming birds further up north, spurring questions of how they evolved and what happened to them.

SciShow explains the chemistry, archaeology and history of bog bodies -- naturally mummified corpses (and other fun things!) that have been discovered in Europe's peat bogs.

As a species, we like to think everything about us is one of a kind, including the Milky Way Galaxy, but new evidence shows that yet again, we're not so unique.

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

A mother and son trek across an endless desert. Wearing special suits to dissipate heat and recycle moisture, the travelers aren’t worried about dying of thirst. Their fears are much greater. Soon, the sound of the desert is drowned out...

There’s no question that comets have been regarded as some of the most beautiful things in the night sky for thousands of years. But why are their heads often green but never their tails?

This video is about the cosmic distance scale and how we see objects farther away in space (ie at...

Sure, honeybees make delicious honey. But have you ever heard of propolis, the spitty glue they use to mummify intruders?

Scientists were able to get molecular information from 1.7 million years old teeth using a new method that could completely change how we study extinct organisms.

Hank talks about ancient sexy times, and how we know that early humans were getting it on with all kinds of folks.

We all have origin stories and identity myths, our tribal narratives that give us a sense of security and belonging. But sometimes our small-group identities can keep us from connecting with humanity as a whole -- and even keep us from...

In the 1960s drug-resistant strains of malaria emerged, making the disease even deadlier than before. Then, pharmaceutical scientist Tu Youyou discovered a promising new remedy buried within the pages of ancient Chinese texts.

The Socotra archipelago in the Arabian Sea supports so many diverse and unique species that it has been described as the most alien place on Earth. Hank takes you on a tour of this weird place in this episode of SciShow.

Where there's life, there's other life looking for a free ride. Here are six of the world's oldest parasites.

Working in Vienna at the turn of the 20th century, he began his career as a neurologist before pioneering the discipline of psychoanalysis, and his influence towers above that of all other psychologists in the public eye. But was Sigmund...

Researchers have found ancient communities of microbes that have been buried deep, for a hundred million years! This discovery might be the oldest living thing on Earth, and could even expand the search for life on other planets.
