Framed by five popular theories of human nature: creationism, spiritualism, social constructivism, biological determinism, and evolutionism, this album tackles some of the big questions in philosophy, psychology and science, with the help of top science writers David Buss, Olivia Judson, and David Sloan Wilson. Provocative and fascinating subjects (She’s Ovulating, The Evolution of Gayness, Twin Studies) are deftly spliced with some incredible beats and turntablism to bring you hip-hop as you’ve never heard it before.
