I do not think; and if Mr. Ben spent the next thought with which he began, he
he probably would have seen that this is impossible. As already mentioned, he openly
adopts "the natural-historical method", as it not only refers to
him in the Preface, but it leads in the first Chapter examples of Botanical and
Zoological classifications as the explanation of the manner in which he
proposes to develop mental excitement. We recognize this philosophical
vision and only regret that Mr. Bain has overlooked some of her
the most important conclusions. In fact, what was the essence of progress
natural history classification? The abandonment of the habit group
items external, outstanding characters and in making, by the base groups,
some internal and most significant features. Whales now
time is not added more to the fish merely on the ground that
forms and manners of life they resemble fish; now they are referred to
mammals, because the type of organization, how it is found
anatomical studies, corresponds to the type of mammals. Polyzoa, on
first, because of their shape and method of growth, were viewed as
kelp, now, the study of their internal structure and activities
be belonging to the animal Kingdom. So, obviously, the opening
real affinity involves the analysis. Now they found that the former
classification rukovodilac General similarity, though, is a lot
true and were useful for a time, were in many cases radically
false and that the true affinities of the organisms present and their compliance with
parts can be opened only by the study of the internal structure.
We also note another very important fact in the history of the classification. Very
often even a thorough analysis is unable to detect the affinity of organisms
if this analysis is limited to the structure of organisms only in Mature
age. In many cases, it is necessary to investigate the structure of the body on it
early stages and even in his infancy. For example,
to determine the present position of the cirripeds between animals, exploring only
Mature individuals, it was before difficult, that Cuvier erroneously considered them to
shellfish even after their anatomy; and not before, as you open them
the earliest forms, it was found that they belong to the crustaceans. In fact,
a study of the development, as a means of classification, so it is important that advanced
zoologists of our time think it is the only absolute criterion.
