ABSTRACT
The kinematics of swings at joints can be described fully by means of two simple ratios and the angle at which the total operative force vector pulls upon a bone. The ratios can be applied to individual muscles, thus linking structural and functional myology in an exact way. The 'spurt' and 'shunt' types of muscle are sharply distinguished, both kinematically and anatomically.

CONCLUSION: It would seem then, that the concept of evolution can be arrived at by a deduction from an axiom applicable to the descendants of a pair of bisexually reproducing ancestors, but excluding hermaphrodites. The generalization of the concept to cover all other organisms, including hermaphrodites, must be by an induction from the results of the said deduction. Such is the logic of the affair.
