Did Neanderthals sing? Is there a “music gene”? Two scientists debate whether our capacity to make and enjoy songs comes from biological evolution or from the advent of civilization.

Music is everywhere, but it remains an evolutionary enigma. In recent years, archaeologists have dug up prehistoric instruments, neuroscientists have uncovered brain areas that are involved in improvisation, and geneticists have identified genes that might help in the learning of music. Yet basic questions persist: Is music a deep biological adaptation in its own right, or is it a cultural invention based mostly on our other capacities for language, learning, and emotion? And if music is an adaptation, did it really evolve to promote mating success as Darwin thought, or other for benefits such as group cooperation or mother-infant bonding?

Here, scientists Gary Marcus and Geoffrey Miller debate these issues. Marcus, a professor of psychology at New York University and the author of Guitar Zero: The New Musician and The Science of Learning and Kluge: The Haphazard Evolution of The Human Mind, argues that music is best seen as a cultural invention. Miller, a professor of psychology at the University of New Mexico and the author of The Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature and Spent: Sex, Evolution, and Consumer Behavior, makes the case that music is the product of sexual selection and an adaptation that’s been with humans for millennia.
