NATURE
Big Birds Can’t Fly

NATURE: Big Birds Can't Fly

 

This is the unique story of flightless birds. They say a bird is three things – feathers, flight and song. But what happens when you’re a bird who can’t fly, who can’t sing, and whose feathers are closer to fluff? Flightless birds include ostriches, emus, rheas, cassowaries and kiwis, and, interestingly, all have evolved independent of each other on different continents. Research has shown that some of these big birds at one time could fly, but once the dinosaurs were wiped out, these same birds no longer needed to take flight from their enemies. As they began to explore a world rich with food and free from predators, they grew fat, and their legs grew long and strong – until the day they discovered that although they had become good at walking, they’d also become too heavy to fly.

NOVA
Mystery of Easter Island

NOVA Mystery of Easter Island

 

A remote, bleak speck of rock in the Pacific, Easter Island, or Rapa Nui, has mystified the world ever since the first Europeans arrived in 1722. How and why did the ancient islanders build and move nearly 900 giant statues, or moai, weighing as much as 86 tons each? And how did they transform a presumed paradise into a treeless wasteland, bringing ruin upon their island and themselves? NOVA explores controversial recent claims that challenge decades of previous thinking about the islanders, who have been accused of everything from ecocide to cannibalism. Among the radical new theories is that the islanders used ropes to “walk” the statues upright, like moving a fridge. With the help of an accurate 15-ton replica statue, a NOVA team sets out to test this high-risk, seemingly unlikely theory – serving up plenty of action and surprises in this fresh investigation of one of the ancient world’s most intriguing enigmas.
