A language that can be spoken, hummed, or whistled? A language with no unique words for colour or numbers? Linguistics professor Daniel Everett claims that the unique language of the Piraha people of the Amazon is exactly that. More than 30 years ago, he travelled as a missionary into the Amazon rainforest to teach the tribe, but they ended up teaching him. Their way of life and unique form of communication have profoundly changed Everett, and inspired a theory that could undermine the most powerful theory (or theorist) of linguistics.
Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples.
Why are we the last of our kind? Anthropologist Niobe Thompson takes a journey of discovery in the footsteps of our human ancestors, and unlocks the mystery of our unlikely survival and miraculous emergence as the world's only global species. We evolved during the most volatile era since the extinction of the dinosaurs. Like the many other kinds of human who once shared our world, Homo sapiens should have died away. Instead, our species survived to populate every corner of the planet. How did we do it? How did humans overcome near extinction in an African super-drought? How did we find a doorway through the Sahara and out of Africa? What happened when we met the Neanderthals? And how did humans master the Arctic and cross the oceans? Dr. Niobe Thompson takes the audience inside groundbreaking scientific research to reveal dimensions of the human journey we once thought was impossible. In a series of expeditions to some of the world's most remote cultures, including the world's last free-diving sea nomads, the Crocodile People of Papua New Guinea, Bushmen of the Kalahari, and reindeer herders of the Russian Artic, Dr. Thompson gives us a never-before-seen window on our species' past. In the process, we discover the fragility of human life and the miracle of our adaptable, imaginative, and curious nature. Part 1: Rise of a Species Like other kinds of human who once shared our world, homo sapiens should have died away. Discover how our species faced near extinction in Africa, and then found a place to rebuild. Explore the birth of language and art at archeological excavations scientists are now calling "the cradle of the human mind".
In previous decades, most news with global reach came from several major newspapers and networks with the resources to gather information directly. The speed with which information spreads now, however, has created the ideal conditions for something called circular reporting. Noah Tavlin sheds light on this phenomenon.
