A lively, informal look at a fossil that may represent the first vertebrate to emerge from the ancient seas, discovered by scientists from the University of Chicago, Harvard University and the Academy of Natural Sciences in Philadelphia.

The coelacanth, a prehistoric fish that was mistakenly thought to have gone extinct at the same time as the dinosaurs, has managed to stick around our seas for 360 million years. Erin Eastwood details the surprising "back from the dead"...

Humans can’t go too far above or below sea level unaided, but there are some complex forms of life that CAN survive at super high elevations or in the deepest parts of the ocean.

Kids love learning about the characteristics of arthropods, fish, amphibians, reptiles, birds, and mammals. Using a fun game show format, students learn that arthropods have an exoskeleton, segmented bodies, and jointed legs. They are...

After stalking a cuttlefish, a moray eel finally pounces. As the eel snags the mollusk in its teeth, its prey struggles to escape. But before it can wiggle away, a second set of teeth lunge from the eel's throat. This adaptation is...

Humans know the surprising prick of a needle, the searing pain of a stubbed toe, and the throbbing of a toothache. We can identify many types of pain and have multiple ways of treating it - but what about other species? How do the...

Wouldn’t it be cool to be able to point at a fossil and know that it’s the first, say, plant? Well... yeah! But it's not that easy! Scientists are always making new discoveries that throw all our old assumptions into...

When we picture the first tetrapods, or land vertebrates, crawling out of the ocean, we probably imagine they need legs. But evolution also had to bestow another important adaptation before they could leave the water: blinking!

Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we're a small part of a complex,...
