Theirs is not as deeply layered or large as humans, but they most definitely have the ability to reason abstractly, are aware of themselves, think emotionally, and engage in complex, time aware planning over long periods. Your views are wrong. Language areas like Broca's region in the human brain are a consequence of physical distribution relative to the connectome and sensory endpoints. If you were to rewire the millions of connections to the lips, tongue, mouth, ears, and other body parts to be locations on the neocortex, broca's region would be somewhere different. You have about 1 square meter of neocortex responsible for all of your perception and cognition, and almost all of it is uniform. Neurons aren't differentiated by function, and animal experiments show that plasticity allows for arbitrary rewiring. The literature in the field shows that human cognition is likely superior to other species in the depth of cortical layering and size of the organ. It's likely the only reason elephants and whales or other animals with larger brains can't compete with humans is the mere absence of hands and vocal organs. Our range of colors and audible senses are important but lesser than many animals. Give an orca hands and human speech and there's nothing we know about neuroscience to imply that the animal wouldn't be smarter and more capable than humans. There's a lot of evidence that the killer whale would be more intelligent than humans in many ways. The cortical layering and columnar architecture of neuron clusters differs between species, and seems to dictate the cognitive depth of abstract reasoning. There may be different algorithmic constructions in neural connections that favor human level cognition. In principle, however, human brains aren't terribly different from many other large mammals, and elephants certainly display complex, emotional, symbolic, and abstract reasoning well within a range comparable to human experience. Your notion of animal cognition is unscientific and biased toward an assumption of human superiority that isn't grounded in fact. Neuroscience is slowly and tirelessly matching toward reverse engineering the brain. The more we learn, the more we find similarity in the basic functions of mammal brains, from mice to humans to blue whales. |
