Higher mammals, such as humans, have markedly larger brains than other mammals. Scientists recently discovered a new mechanism governing brain stem cell proliferation. It serves to boost the production of neurons during development, thus causing the enlargement of the cerebral cortex -- the part of the brain that enables us humans to speak, think and dream.
