“This book forwards the hypothesis that schizophrenia is a product of very recent evolutionary events. Although humans, or something like them, have been around for some six million years, language has been extant for a mere 50,000 to 100,000 years. The onset of language was afforded by skyrocketing advances in brain development, the central nervous system ballooning incrementally over eons of time to the point where the fetus's little head could barely navigate Momma's birth canal. The Horno sapiens brain profited from a unique folding of the cerebral cortex, allowing for greater speed and a sly adeptness at symbol formation that led to speech.” — Steven Lesk M.D.
