Brains Are Not Required When It Comes to Thinking and Solving Problems—Simple Cells Can Do It
Many human morphological and behavioral characteristic — musicality, sense of rhythm, use of dissonances, entrainment, bipedalism, long head hair, long legs, strong body odor, armpit hair, traditions of body painting and cannibalism — are explained as predator avoidance tactics of an aposematic (warning display) defense strategy. […] Unlike crypsis, which is based on the strategy of remaining invisible, silent, odorless, and fleeing as quickly as possible if discovered by a predator, aposematism is the alternative defense strategy of intimidating predators by remaining visible, being noisy, presenting odor, and, rather than fleeing when confronted by a predator, actively approaching and threatening the predator with body size, loud sounds, odors, and fearless behavior. […] Humans are among the very rare terrestrial species that sing, though arguably some carnivores (e.g., wolves and coyotes) can also sing, and sing in choruses […] Early humans came down from the trees, and tree-living birds and primates (including a lesser ape, gibbons) are among the most ardent singers, so it would be logical to propose that our arboreal common (humans and apes) ancestor was a singer. The long-standing question that comes with this suggestion is why do terrestrial apes not sing? […] Many singing and noisy arboreal species (birds and monkeys) maintain silence whenever they visit the ground as a cryptic defense strategy from potential ground predators. Most likely, the ancestors of chimpanzees, gorillas and bonobos stopped singing for the same reason—maintaining cryptic cover while on the ground. On the other hand, in a strategically different move, early humans continued singing, therefore changing their survival strategy from cryptic into aposematic. […] I propose that not stopping singing was probably the first and deciding move toward the new aposematic strategy of defense in the hominin lineage, followed by the other elements of aposematic display.
