Further, very few tools existed in historical times where handedness mattered at all. A wrench or a hammer or a spear have no handedness. Only much later were tools invented to meet the needs of the majority or users, which is why there was a tendency to put controls on power tools on the right.
The whole thesis mistakes cause for effect, suggesting tools and games we invented had something to do with what made us what we are. Whether our ancestors threw the spear, or picked the berry right or left handed couldn't have mattered at all.
The mention of a wrench here is a perfect example of how to overlook favorable tendencies for left/right handedness. Yes, the tool itself can be used in either hand, but the direction in which nuts and screws are wound in typically favors right handed people. Similarly, scissors with no ergonomic shape to favor one hand over the other typically have the top blade on the right, which leaves the cut much easier to see if the scissors are held in the right hand.
I'm not intimately familiar with tools mankind has used throughout history, but I'd be cautious to make statements like "very few tools existed in historical times where handedness mattered at all".
