I’ll give you a hand here:
Later amended to:
And specifically:
His “best research available” to support that was a series of cites explaining scale effects, specifically why animals whose masses cover 5 orders of magnitude all have similar jumping abilities: e.g. “grasshoppers, cats, people, and horses can all jump about a meter.” The cites were meant to *explain *the commonly observed *scale *effect, not rigorously set a limit on performance of animals having widely different physiologies.
To Blake’s credit, he relaxed his definition of “about a meter” after someone pointed out that vertical leaps by humans of well over a meter have been recorded. But he apparently still thinks that his cites confirm that “no members of a jumping species raise their centers of gravity more than about about one meter when they jump” when they don’t. At all.
Indeed.
