The mind is the central organ answerable for the adaptive capacities of animals. What has inspired scholars of biology, of medication, and, to an volume, of philosophy is the correlation among the prominence of the cerebral cortex and the adaptive "complexity" of a specific spe­ cies. so much agree that the cortex is what units Homo sapiens except different species quantitatively and qualitatively (Rakic, 1988). this can be summarized within the first chapter.
