Beginning in the late nineteenth century and throughout the twentieth century, geologists, archaeologists and paleoanthropologists have given the world evidence of the physical and cultural development of humans. This video looks at how...

Purgatorius, a kind of mammal called a plesiadapiform, might've been one of your earliest ancestors. But how did we get from a mouse-sized creature that looked more like a squirrel than a monkey -- to you, a member of Homo sapiens?

Pupil outcome: I can identify similarities and differences in humans within a family tree. Key learning points: - A family tree is a diagram that shows the relationships between all the people in a family over many generations. - The top...

All humans share some common bits of DNA, passed down to us from our African ancestors. Geneticist Spencer Wells talks about how his Genographic Project will use this shared DNA to figure out how we are -- in all our diversity -- truly...

Growing up in America I always identified myself as “Half Polish”, this was a normal part of my identity as my Great Grandmother sent packages containing my childhood clothing to relatives in Poland. When she passed away the contact...

In part 1 of our special series on human ancestry, we tour through our family tree to meet our ancestors and distant cousins, and to find out what made us human along the way. The story of human ancestry is not a simple progression from...

Learn the basics of language history and how languages change over time. This lesson introduces the essentials of the comparative method. We'll use cognates to group related languages into family trees. Related languages trace their...

Over millions of years, a few plant species at the bottom of the plant family tree have evolved and multiplied into thousands of new species. Each new plant is of a different shape, texture, colour and size, and can sometimes be entirely...

Taxonomy is a powerful tool, and one that modern biology wouldn't be able to function without. But trying to shoehorn the messy, complicated web of interrelationships that is biology into neat boxes has resulted in a pretty messy tree of...

There’s one kind of herpesvirus that’s specific to one species of primate, and each virus split off from the herpesvirus family tree when the primate split off from its own tree. But of course, humans are a special kind of primate.

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.

Alright, we've learned about how unicellular organisms came to be, how they became multicellular, and then from those how evolution by natural selection produced all the species in the world today. But there are so many! Millions and...

In part 3 of our special series on human ancestry, we investigate how closely related we all really are. Basic math tells us that all humans share ancestors. But you'll be amazed at how recently those shared ancestors lived. Thanks to...

The older the word, the longer (and more fascinating) the story. With roots in Old English, 'true' shares etymological ancestors with words like betroth and truce...but also with the word tree. In fact, trees have been metaphors for...

We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

The tools made by our human ancestors may not seem like much when you compare them to the screen you’re looking at right now but their creation represents a pivotal moment in the origin of technology and in the evolution of our lineage.

New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world. The exact cause remains to be determined, but...

Researching the farthest branches of your family tree is now faster, cheaper, more accessible and more accurate than ever before. Today you can find distant living relatives, learn how you are related to important historical figures or...

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.

If you traced your family tree back 185 million generations, you wouldn't be looking at a human, a primate, or even a mammal. You'd be looking at a fish. So where along that line does the first human show up? The answer may surprise you

Historic Time expands the concept of time into the larger units of years, decades, centuries, and eras. The video explains the meaning of generations and ancestors and illustrates where the viewer fits into the family history - this is...

This week we learned that the Neanderthal/Denisovan/Human family tree is pretty complicated, thanks to a close look into some Neanderthals' Y chromosomes.
