> different mental and behavioral pattern then people today
That’s bulshit. Behavioral pattern is a term from ethology and depending on context it could be argued that humans exhibit similar behavioral patterns to most social primates. Mentally modern man is the same as Cromagnons and <some argue> perhaps slightly inferior to Neanderthals (they had a significantly larger brain).
