Trace the ancient history of the pigeon, and discover how these birds became one of the most abundant species on the planet.

--

Seeing their meat as a protein source and their poop as the perfect fertilizer, humans brought pigeons into captivity as far back as 10,000 years ago. As we carried pigeons around the world, they formed the wild urban flocks we're familiar with today and became one of the most abundant species on the planet. Elizabeth Carlen and Joanna Moles track the feathery flier's rise to world domination.

Lesson by Elizabeth Carlen and Joanna Moles, directed by Joseph Clark, Oh Studio.

Dig into the science of how ancestry DNA tests work, their accuracy, and why tracing ancestry is so complicated.

Uploaded 09-06-20

--

Two sisters take the same DNA test. The results show that one sister is 10% French, the other 0%. Both sisters share the same two parents, and therefore the same set of ancestors. So how can one be 10% more French than the other? Tests like these rely on our DNA to answer questions about our ancestry, but DNA actually can’t tell us everything. Prosanta Chakrabarty explores the accuracy of DNA tests.

Lesson by Prosanta Chakrabarty, directed by Artrake Studio.

As millions around the world shelter at home, the smog melts away, the birds sing, and the waters run clear.

This moment can lead us to a healthier, cleaner, greener future, if only we grasp it. Tom Rivett-Carnac tells the story of what happened when we all stopped.

In one of Aesop’s fables, a crow is searching for water. It spies a pitcher— but the water inside is beyond its reach. So, the crow begins dropping in pebbles. One-by-one, they displace the water, and the crow quenches its thirst. This is just one of many fascinating displays of intelligence from corvids. Katharina Brecht digs into what makes this bold, brainy family of songbirds so smart.

Dig into the Greek myth of Meleager, who set out to end a boar’s destruction of his city along with Greece’s best warriors.

--

The night of her son's birth, the queen of Calydon was visited by three shadowy goddesses, known as the Fates. They gestured towards the blazing hearth and decreed that her son would live only until the burning log was reduced to embers. Terrified, the queen locked the log in a chest and guarded the key— but the secret would loom over his life. Iseult Gillespie shares the Greek myth of Meleager.

Lesson by Iseult Gillespie, directed by Layron DeJarnette, Gumboyo Animation.
