... we must first base such words as between upon clear concepts, a thing which is quite feasible but which I have not seen done.
In 1891, during the Presidency of William Henry Harrison [Benjamin Harrison], electric lights were first installed in the White House, the residence of the leaders of our country. At that time, commercial electricity was not economically feasible, but President Harrison wanted to affirm his confidence in the technological capability of our country.
It is tautological to say that an organism is adapted to its environment. It is even tautological to say that an organism is physiologically adapted to its environment. However, just as in the case of many morphological characters, it is unwarranted to conclude that all aspects of the physiology of an organism have evolved in reference to a specific milieu. It is equally gratuitous to assume that an organism will inevitably show physiological specializations in its adaptation to a particular set of conditions. All that can be concluded is that the functional capacities of an organism are sufficient to have allowed persistence within its environment. On one hand, the history of an evolutionary line may place serious constraints upon the types of further physiological changes that are readily feasible. Some changes might require excessive restructuring of the genome or might involve maladaptive changes in related functions. On the other hand, a taxon which is successful in occupying a variety of environments may be less impressive in individual physiological capacities than one with a far more limited distribution.
