(1) The museum-makers of old days and their modern representatives the curators and describers of zoological collections, (2) early explorers and modern naturalist travellers and writers on zoo-geography, and (3) collectors of fossils and palaeontologists are the chief varieties of zoological workers coming under this heading.
The most instructive classification of the variations exhibited by fully formed organisms consists in the separation in the first place of those which arise from antecedent congenital, innate, constitutional or germinal variations from those which arise merely from the operation of variation of the environment or the food-supply upon normally constituted individuals.
It has been argued that the elaborate structural adaptations of the nervous system which are the corporeal correlatives of complicated instincts must have been slowly built up by the transmission to offspring of acquired experience, that is to say, of acquired brain structure.

 Scientific classification - Wikipedia, the free encyclopedia
Scientific classification can also be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks any proper scientific basis.
Advances in classification due to the work of entomologists and the first microscopists is due to the research of people like Marcello Malpighi (1628–1694), Jan Swammerdam (1637–1680), and Robert Hooke (1635–1702).
The usual classifications of five species follow: the fruit fly so familiar in genetics laboratories (Drosophila melanogaster), humans (Homo sapiens), the peas used by Gregor Mendel in his discovery of genetics (Pisum sativum), the "fly agaric" mushroom Amanita muscaria, and the bacterium Escherichia coli.

These systems group living organisms on the basis of the traits they share with other organisms and on their genetic relationships with each other.
In this system, organisms are grouped into the categories of kingdom, phylum, class, order, family, genus, and species, with each successive grouping containing fewer organisms that are more closely related.
However, this classification is based on the panda's genetic traits and anatomical features, and not on their eating habits.

 Zoological Philosophy: I, Part 1, Chapter 5   (Site not responding. Last check: 2007-10-24)
The case is different with classification, that is to say, with the different lines of separation which we are concerned to trace from place to place in the general distribution, whether of animals or plants.
In fact, although nature does not move abruptly from one structural system to another, it is possible to establish some limits between each system, so that throughout nature there is only a small number of animals placed near these limits and in a position to raise some doubts about their true class.
And it is these particular systems which are going to deteriorate from the one which shows the greatest complexity right to the one which is the simplest.

 Classification
Systems of biological classification did not make much significant progress for about 2,000 years after Aristotle's contribution, until a Swedish Professor of Botany devised a new organizing principle, and applied it to a taxonomy of plants, animals and later minerals and diseases.
He had invented the binomial system of naming creatures, or what can be considered to be a binary nomenclature.
The combination of an easy to remember binomial name (even if it was in Latin), and the ease with which new organisms could be identified, characterized and then fitted into their respective groups and grouping, gave the Linnaean system of classification a utility that greatly exceeded its artificiality.

In the adult state it forms a double sigmoid curve, caused, in the dorsal and sacral regions, by the conformation of the vertebræ–in the cervical and lumbar regions, by the elasticity of the ligamenta subflava connecting the posterior arches.
The teeth of man are composed of the ordinary constituents, cementum, dentine, and enamel, are fixed in alveolar sockets, and consist of a temporary and permanent set, the latter replacing the former vertically.
In connection with the cutaneous system may be mentioned the great accumulations of fat in particular parts of some races, as on the buttocks of the Bosjesmen, more especially the females; and also the great development of the nymphæ in some negro tribes.

This system was adopted quickly as is or in modified form by many libraries.
The other standard book classification, and the one which most Americans will encounter, is the Library of Congress Classification system (LC), which was also conceived and introduced in the last part of the nineteenth century.
Since the Library of Congress Classification System is used in every college and university library in the USA, then mastering it will apply to any college or university a student attends.

The system allows for the construction of a variety of classifications by using Node objects.
I don't care to use the species because that ties the records to a Linnaean classification system and would be redundant.
At each level of the Linnaean System there are a number of other Nodes--many Families under the same Order, many Species under the same Genus, etc. These systems all use the same animal records.

Because systems of classification are not perfect in capturing the complexity of life, the continued availability of biological research collections is crucial.
The collections of the Zoological Museum preserve the type specimens that formally link taxa to names; they provide an objective testimony of the occurrence of a taxon at specific times and places they permit us to understand how scientists in the past constituted taxa; and finally they provide the materials for further research.

 Subspecies and Classification
The common perception of classification as conforming with and representing phylogenetic hypotheses must be superimposed upon the even more basic responsibility of reflecting biodiversity.
To limit the scope of these dual responsibilities of classification by exclusion of subspecies, through their distortion by elevation to species rank, or through abandonment, in order to reflect phylogeny at all classification levels, is unwarranted.
To exclude valid taxonomic entities from classification misrepresents fact and neglects a level at which a major part of evolution is occurring at all times and at varying rates, although it is little studied, understood, and appreciated in most groups of animals.

 ASIS '96: Weinberg, B.
The past hundred years have seen the development of numerous systems for the structured representation of knowledge and information, including hierarchical classification systems with notation as well as alphabetical indexing systems with sophisticated features for the representation of term relationships.
As that category system grows, all the problems experienced by librarians in the area of classification will be encountered: accusations of bias, lack of currency, and lack of specificity.
It is hoped that the systems for organizing information which were developed in the last century will not be ignored, that their design flaws will not be replicated, and that our increasing knowledge of human factors will be incorporated into systems for indexing the Internet.

Some systems are more useful for public access, others for private access, and different systems have been devised in different countries, which may be geared specifically to given language or culture or specific to a particular academic discipline.
It's what is known as a universal system, that is one which is not specific to any one field but which can be used in a multi-disciplinary way.
These systems are far and away the most common means of classification, and others include the Universal Decimal Classification and the classification scheme devised by the Library of Congress in Washington, DC.

ANIMAL [animal] any member of the animal kingdom (kingdom Animalia), as distinguished from organisms of the plant kingdom (kingdom Plantae) and the kingdoms Fungi, Protista, and Monera in the five-kingdom system of classification.
Almost all animals, unlike most plants, possess a limited scheme of growth; that is, the adults of a given species are nearly identical in their characteristic form and are similar in maximum size.
In zoological classification the animal kingdom has been divided into the three subkingdoms of Parazoa (the sponges), Mezozoa (wormlike parasites), and Eumetazoa.
