Madagascar is a land where lizards scream and monkey-like lemurs sing songs of inexpressible beauty. It is a place where creatures you may never have heard of--fossa and tenrecs, vangas and aye ayes--thrive in a true 'Lost World' along with bizarre plants like the octopus tree and the three-cornered palm. And where the ancestors of the Malagasy, as the island's people are known, come alive in rollicking ceremonies known as "turning the bones." Join Peter Tyson on a diverting odyssey with four scientists investigating the fascinating natural and cultural mysteries of this extraordinary land.
