The presence of these and other structures included as anomalies partially illustrates the conservative power of heredity. Probably no organ is stationary in development, although apparently it would seem so under certain conditions of environment; this, however, is occasional, and physiological and biological evidence goes far toward proving that almost all organs are in a state of change, some more rapidly than others, arid here it may be mentioned that man, as a whole, is in a state of evolution almost as rapid as that which has produced the modern horse from its small five-toed ancestors. Looking into the subject practically, the difference in determining whether an organ is developing or degenerating at the same time is great; its variability or tendency to present individual anomalies indicates that some change is taking place. This is shown in the very variable peronaeus tertius (Wood) and numerous other muscles, among which is the palmar is longus. Now, as change of organ is associated with degree of utility, in the analysis we must include the amount of service rendered by the part, and, as this is often determined by the amount called upon for the maintenance of function necessary to health under various conditions of life, a few words upon the influence of habit will not be amiss. In the production of anomalies in individuals we have as factors the destructive power of degeneration, which is essentially adaptive as against the protective power of heredity, and the result may be viewed minus or plus the influence of habit and the various conditions of life.
