Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

In the tradition of Jared Diamond and Jacques Barzun, prize-winning historian Anthony Pagden presents a sweeping history of the long struggle between East and West, from the Greeks to the present day.

The relationship between East and West has always been one of turmoil. In this historical tour de force, a renowned historian leads us from the world of classical antiquity, through the Dark Ages, to the Crusades, Europe's resurgence, and the dominance of the Ottoman Empire, which almost shattered Europe entirely. Pagden travels from Napoleon in Egypt to Europe's carving up of the finally moribund Ottomans - creating the modern Middle East along the way - and on to the present struggles in Iraq.
