dc:description "Downloaded the Dryad version zip and read the tab-separated claw table as latin-1. Counted males and females with both loss flags equal to zero, which means both the crusher and the scissor claw were present. Looked for a second claw width so the pre-registered 5 percent comparison could be computed. The table has CrusherClawWidth and no scissor-claw width, so no individual was scored as equal or unequal.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 0 individuals whose two claw widths were both present in the table (n = 2560). Interpretation: The quote is: There is no apparent difference between the male and female, for they both have one claw, whichever it may be, larger than the other, and neither male nor female is ever found with both claws of the same size. Lobster is read as Homarus, the clawed lobster, not every decapod. The claim is about both sexes and about the absence of equal claws. Which side is larger is not part of the claim. The denominator is the measured lobsters, not every lobster.";
