Harari provides a one-hundred-thousand-year history of science and human evolution. Derek Perkins narrates as the author describes the six varieties of human species, the major genetic mutations that took place, and the interbreeding that ultimately resulted in the humans we are today. Clearly and succinctly, Perkins explains the complex changes in the physical, mental, and emotional attributes of Sapiens and discusses how Sapiens and Neanderthals interacted with each other. As Perkins tackles this complex history of the cognitive, agricultural, and scientific changes that converged to make us human, Perkins’s meticulous pace is perfect. His skill allows listeners to absorb each fact and ruminate about these complex evolutionary theories. © AudioFile
