Along the wild edges of the Earth, against a stunning backdrop of aerial, underwater, and wildlife photography, evo-devo guru Armand Leroi leads us on an unforgettable journey retracing the adventure-and uncovering the evidence-that inspired Darwin's revolutionary work, On The Origin of Species. It's the story we haven't heard. Though he circled the world on the "Beagle" for five years, Darwin spent only five weeks on the famed Galápagos. He had no epiphany there-no Newton's apple falling from the tree. So what was it? What "certain facts" from the voyage led this young Creationist to propose a theory so radical it remains controversial (though widely proven) 150 years later?
