Interesting, but the active voice is rather misleading in the headline.
The argument seems to actually say the expected: Humans who used stone tools were selected based on their tool use -> humans more suited for stone tool use continued to be selected -> stronger hands & wrists.
I guess it serves some purpose to find specimens which verify the expected. Perhaps some less obvious insight will come of this.
