Also, all organisms have a concept of language and auditory sounds - it's the recognition and association to meaning that is recieved within the human brain. This is merely memory. Consider that other animals still recognize loud and scary sounds, tones (how a dog acknowledges you, etc.), and even some animals have much more advanced hearing and recognition than humans (cats, for example).
I think they may have some of those capacities, but not a concept of them. And the more advanced capabilites were born out of necesity. while our brains evolved toward a differant evolutionary standard of writing, reading language (not such rudementary language as animals), & math.
"Throughout the animal Kingdim , capacities are not lateralized. Instead they tend to be found in both hemispheres to roughly equal degrees. And although monkeys show some signs of lateral specialization, these are rare & inconsistant."
"For this reason it appears that the lateralization seen in the human brain was an evolutionary add on - mechanisms or abilities that were laid down in one hemisphere only." (like language and writing)
"In what must have been a fierce competition for cortical space. The evolving primate brain would have been hard pressed to gain new faculties without losing old ones."
Through evolution the emergance of a human capacity like language or an interpretive mechanism chases the perceptual skill out of the right brain.
