“Robert McNeill Alexander showed how the speed of an animal could be calculated from the spacing of its footprints and its body size.”
VERIFIED BY REFERENCE
Wikipedia entries mention Alexander's work in biomechanics but do not specifically confirm his method for calculating animal speed from footprints and body size. No direct evidence supports the claim.
