1. I would tend to agree that the initial discovery of the “artificial” edge was accidental, but the idea of that had to register in someone’s brain in order to have been repeatable and teachable to others.sal wrote:I would like to add 3 concepts:
1) I would argue that no one "got the idea". I would argue for accidental discovery. Hitting a rock accidentally with another rock fractured the edge or accidentally hitting a rock with another rock accidentally "sharpened" the edge.
2) I would argue that the sharpened stick was before the sharpened rock.
3) I would argue that the first "Purpose" of stick/rock was for weapon. Either defense or hunting, than for processing.
A stick can be sharpened by dragging it on the ground or against a rock. I remember when I discovered this as a four year old. Soon, I had sharpened every stick I could find by dragging it against rocks and sidewalks.MichaelScott wrote: 1.

2. I would have to ask how sticks were sharpened without a tool, which would most likely have been a sharp rock.
3. I have to say that it could have gone either way. Without access to the daily living habits of those early hominids, it’s not likely we will know. In basic hunter-gatherer societies men typically hunt and defend while women process non-meat food and care for the very young. Both activities benefitted from sharp rocks and sticks.
