I guess the question I’ve always wondered is…..What suddenly changed that gave our ancient human ancestor the ability to start progressing intellectually that wasn’t capable of happening to any other animal….If we keep moving back in time, we as a specie decline in intelligence and brain capacity…. Where was the point in time that our brains diverged and started getting progressively smarter and what caused it??....Why were WE the only animal that benefited from whatever this event or change might have been?.....To me that would be the moment we became human and what separated us from all of the other animals…..the biting of the apple
Nothing “suddenly” happened. But introducing high caloric value food (meat), cooking methods, ability to communicate & teach the next generation so each new born doesn’t have to re-invent the wheel….all these things slowly helped us eventually rise to the top.
