Did abstract concepts occur to our earliest ancestors before they started communicating them? That seems very likely. Yet, did we start counting before developing complex languages, or did we start talking after we started counting?
In other words, did human semiosis precede counting and primitive arithmetic, or did language evolve because of counting and numbers?
Naturally, this conundrum prompts another question, why or how did human communication and complex thought begin at all? Regardless, the mystery of why only some apes (not all of them) became humans will probably remain mysterious.
Of course, the many environmental challenges and physiological adaptations that favored human family culture, successful child-rearing, and positive emotional bonding must be considered essentials. However, some researchers now consider the possibility that biochemical factors, especially ingestion of psychedelic and neuro-adaptive fungii (etc.), may have been critical keys to the inception of uniquely human neurological development and psychosocial evolution.
That seems very likely. After all, even some non-psychotropic fungii and plant compounds are now known to promote growth of new neuronal networks. Compelling experiments with mice show truly the powerful neurogenesis after treatment with psylocibin. Interestingly, the behavior of the mice changed in favor of eliminating the effects of trauma and habitual fear. In other words, even mice prefer happy enjoyment more than suffering.
So, if brain-enhancing fungii help mice improve their lives, is it reasonable to assume that our earliest hominid ancestors were less motivated to improve their lives?
Now, the most important question may be: why do so many modern humans seem to prefer maintaining causes of suffering and habitual fear? On the other hand, it seems more important to ask: how can we rescue ourselves and our habitat (if possible)?
I look forward to your insights, etc. ~ M
