Document Summary
A bit of a chicken and egg problem . Musical perception is genetically coded and present near birth in most infants. Evolution of motor control of vocal tract and hands. Kimura (1979) postulated the evolution of lateralized fine motor control of the right hand co-evolved with the lateralized fine motor control of the oral musculature (specialized for making speech sounds) Evidence suggests 2 types of neurons in primary motor cortex one type that synapses directly to spinal motor neurons and one type that synapses indirectly, through an interneuron. Not all who wander are lost (j. r. r. Cognitive neighborhoods are the evolutionary emergent world of the foraging mind. Similarities in foraging behavior across eumetazoans (vertebrates, insects, and mollusks) suggest the early evolution of a foraging behaviour called area-restricted search. Area-restricted search is characterized by initially concentrated searching around local areas of highest historical payoff, followed by more global and less focused searching as payoffs become infrequent.
