From Discover:
Look anywhere and you’ll find music. Without a single exception, every culture produces some form of it. Like language, it’s a universal trait in our species, and over the millennia it has bloomed into a diverse and stunning global symphony. Yet its origin remains one of the great secrets of human history.Share
The oldest known instruments are 42,000-year-old bone flutes discovered in caves in Germany. Vocal music surely predates these, but the problem, according to University of Amsterdam musicologist Henkjan Honing, “is that music doesn’t fossilize and our brains don’t fossilize.” With little hard evidence, scientists still debate what evolutionary purpose music serves. And because its purpose is obscure enough to warrant debate, some skeptics question whether it serves any purpose at all.
Charles Darwin thought it did. In music, he found evidence for his lesser-known theory of sexual selection. Drawing a comparison with birdsong — which is partially a courtship tactic — he proposed in his 1871 book The Descent of Man that although our melodiousness doesn’t help us survive from day to day, it could have evolved “for the sake of charming the opposite sex.” (Read more.)
