Underwater Cave in Madagascar Is Packed with 1,000 Year Old Fossils The subcontinent of Madagascar off southeastern Africa is hot spot of biodiversity, where plants and animals evolved differently than any place else in the world. When humans arrived some 2000 years ago mass extinctions followed. Now scientists have discovered a trove of fossils that could reveal a vanished ecology. In a cave, 130 feet below the floor of the ocean off Madagascar, scientists have found hundreds of bones of extinct animals -- lemurs the size of gorillas and elephant birds. Science writer Brian Switek blogs about fossils at National Geographic . He's also author of My Beloved Brontosaurus : On the Road with Old Bones, New Science and Our Favorite Dinosaurs.
What happens when America retreats from the world? Is President Trump taking his "America First" agenda to extremes, withdrawing the country from the international stage on trade and climate change, distancing America from its traditional allies across the Atlantic and even threatening to physically isolate the country through the building of a wall along its southern border? León Krauze guest hosts.
The Trump agenda: where's the beef? President Trump says big things are happening. After celebrating a House bill on health care, he doesn’t yet have Senate agreement. With James Comey’s public testimony scheduled tomorrow, the President today tweeted his selection of a new FBI Director. Is the Chief Executive all style and no substance? Later, terror attacks in Iran and conflicting claims about who’s behind them.

With time running out, guest host León Krauze looks at what the international community can do to pull the country from the edge of collapse.
