"Last Ape Standing" from science writer Chip Walter

Scientists have determined that at least 27 different species of humans have evolved on planet Earth, yet only one still survives. Why are we still here and our 26 predecessors aren’t? In his fascinating new book, Last Ape Standing: The Seven-Million-Year Story of How and Why We Survived, acclaimed science writer Chip Walter attempts to answer that question as he discusses with Thane Maynard in this week’s Field Notes.
