Sometimes I wonder if the reason humans built some technology that other animal species have not has more to do with the anatomy and physiology outside of the human skull than with the human brain

Humans have certain physical body features that make mining metal and blacksmithing or whitesmithing it easier

Slow twitch muscle fibers

Opposable thumbs

The ability to walk or stand on two legs while holding mining tools above a certain weight and above a certain lever arm size
