From PBS:
Series host and narrator, Alan Alda, confronts the puzzle of why our ancestors in Africa got the Spark and evolved into us, while the first humans to leave Africa for Europe--the Neanderthals--never did. Why did we flourish, while they changed very little for thousands of generations before eventually dying out?
In "The Human Spark," Alan Alda visits dozens of scientists on three continents -- and even undergoes an examination of his own brain -- to find the answer to one question: What makes us human? Coming to PBS over three Wednesdays: January 6, 13, and 20, 2010 (check local listings).
