I’m only 1% serious, but how do we know for sure which direction evolution went in within the ape family?
It seems not entirely unplausible that we have at some point in the scientific chain of custody assumed the “lesser” apes “evolved into” the “more advanced” human.
But a species could easily branch and have the branch lose its geographic portability features (e.g.ability to manipulate environment, most exogenous behavior learning-based) if they are no longer selected for in a particular environment, and I’m not aware of anything in the fossil record that firmly establishes directionality. Am I wrong?
