One of my all-time most “oh so interesting”-provoking articles I’ve found:
A couple of mouthwatering concepts to pique your interest:
Humans are the only ground-dwelling species that sings. There are over 4000 singing species — mostly birds, but also gibbons, dolphins, whales, and seals. But they all sing from water or the trees. When a bird lands on the ground, it invariably stops singing.
When we sing, we almost always dance, even if it’s just nodding along or tapping a foot. Both singing and dancing (whether together or separate) are group activities used across the world in tribal bonding rituals. Isolated ethnic groups have remarkably similar styles of song and dance.
Early hominids quite possibly ate their dead, and (some while later) definitely started burying them. The instinct to preserve a dead human body from mutilation, and then to dispose of it, is fairly universal. E.g. we strive to retrieve corpses even from a battlefield.
The article puts together these concepts and more, into a theory for why humans sing. Super interesting.
