When exploring the etiology of schizophrenia, a feat that has mostly eluded understanding for over 100 years, a common denominator emerges in that associated deficiencies are rooted in cognitively demanding tasks. One suggestion is that, where schizophrenic individuals are involved, disorganised thoughts, abnormal speech, auditory hallucinations and paranoid delusions are symptomatic consequences of our haphazardly evolved brains. It might not seem revelatory, nor is it a particularly new thought on the matter, yet this disorder clearly has ties with human-specific, recently evolved behaviours, such as language and social relationships.
