The name and order Asterales is botanically venerable, dating back to at least 1926 in the Hutchinson system of plant taxonomy when it contained only five families, of which only two are retained in the APG III classification.

At each of these levels a botanist might be concerned with the classification ( taxonomy ), structure ( anatomy and morphology ), or function ( physiology ) of plant life.

Biological classification is a form of scientific taxonomy.

The dominant classification system is called the Linnaean taxonomy.

The classification, taxonomy, and nomenclature of botanical organisms is administered by the International Code of Nomenclature for algae, fungi, and plants ( ICN ).

** Systematics: taxon — taxonomy — scientific classification — phylogeny — evolutionary tree — cladistics — synapomorphy — homology — molecular clock

Bird taxonomy has been in a state of flux for some years, and it is reasonable to expect that the large differences between different classification schemes will continue to gradually resolve themselves as more evidence becomes available.

With the publication of Darwin's theory of evolution in 1859, the concept of a " natural system " of taxonomy gained a theoretical basis, and the idea was born that groups used in a system of classification should represent branches on the evolutionary tree of life.

His classification of plants in his Historia Plantarum, was an important step towards modern taxonomy.

# the particular form of biological classification ( taxonomy ) set up by Carl Linnaeus, as set forth in his Systema Naturæ ( 1735 ) and subsequent works.

That is, taxonomy in the traditional sense of the word: rank-based scientific classification.

The degree to which taxonomy depends on phylogenies differs between schools of taxonomy: numerical taxonomy ignored phylogeny altogether, trying to represent the similarity between organisms instead ; phylogenetic systematics tries to reproduce phylogeny in its classification without loss of information ; evolutionary taxonomy tries to find a compromise between them in order to represent stages of evolution.

It is closely related to numerical taxonomy which is concerned with the use of numerical methods for taxonomic classification.

The 1735 classification of Carolus Linnaeus, inventor of zoological taxonomy, divided the human race Homo Sapiens continental varieties of Europaeus, Asiaticus, Americanus and Afer, each associated with a different humour: sanguine, melancholic, choleric and phlegmatic respectively.

The term " systematics " is sometimes used synonymously with " taxonomy " and may be confused with " scientific classification ".

However, taxonomy, and in particular alpha taxonomy, is more specifically the identification, description, and naming ( i. e. nomenclature ) of organisms, while " classification " is focused on placing organisms within hierarchical groups that show their relationships to other organisms.

Reminded of his lack of expertise in taxonomy, Darwin began an eight year study of barnacles, becoming the leading expert on their classification.

The exact definition of taxonomy varies slightly from source to source, but the core of the discipline remains: the conception, naming, and classification of organism groups.

It was the first in English based on the then new Linnaean taxonomy — a classification of all living things — devised by the eminent Swedish botanist and physician Carolus Linnaeus ( 1707 – 1778 ).

There are many botanical classification systems used for wheat species, discussed in a separate article on Wheat taxonomy.

The classification used within the Historia Piscium was further developed by Carolus Linnaeus, the " father of modern taxonomy ".

Bibliographic classification systems group entities together that are relevant to the same subject, typically arranged in a hierarchical tree structure ( like classification systems used in biology ).

Most classification systems like the Dewey Decimal Classification ( DDC ) and Library of Congress classification also add a cutter number to each work which adds a code for the author of the work.

The AWMT paper did not describe any automatic search, nor any universal metadata scheme such as a standard library classification or a hypertext element set like the Dublin core.

After 1992, the discovery of numerous small icy objects with similar or even wider orbits than Pluto led to a debate over whether Pluto should remain a planet, or whether it and its neighbours should, like the asteroids, be given their own separate classification.

A major feature of phylogenetic classification is the removal of the mammal-like reptiles like this Varanodon from reptiles to their own separate group, the Synapsida

Eris, at the time thought to be the largest TNO, was discovered in 2005, revisiting a long-running dispute within the scientific community over the classification of large TNOs, and whether objects like Pluto can be considered planets.

Before and after aerial photographs and satellite imagery are used to gather landslide characteristics, like distribution and classification, and factors like slope, lithology, and land use / land cover to be used to help predict future events.

The classification of the Cloudinids has proved difficult: they were initially regarded as polychaete worms, and then as coral-like cnidarians on the basis of what look like buds on some specimens.

Although the Dott classification scheme is widely used by sedimentologists, common names like greywacke, arkose, and quartz sandstone are still widely used by nonspecialists and in popular literature.

The international cloud classification system is based on the fact clouds can show free-convective upward growth like cumulus, appear in non-convective layered sheets such as stratus, or take the form of thin fibrous wisps, as in the case of cirrus.

The Belgian climate, like most of northwest Europe, is maritime temperate, with significant precipitation in all seasons ( Köppen climate classification: Cfb ; the average temperature is in January, and in July ; the average precipitation is in January, and in July ).

The province belonged to the region of New Castile ( today Castile – La Mancha ), a region that, just like the rest, had only the purpose of classification, since regions were not autonomous political-administrative divisions.

New London, like the rest of coastal Connecticut lies in the transition between a humid continental climate ( Köppen climate classification: Dfa ) and humid subtropical climate ( Köppen Cfa ), as is typical of much of the Tri-State metropolitan area ( NY / NJ / CT ).

Waynesville experiences a humid subtropical climate ( Köppen climate classification Cfa ) like much of southern Missouri.

The bugle for instance, has the classification number 423. 121. 22, even though it is generally regarded as a relatively simple instrument ( it is basically a bent conical tube which you blow down like a trumpet, but it does not have valves or finger-holes ).

This classification only applies to integers, i. e., non-integers like 1 / 2 or 4. 201 are neither even nor odd.

Broome has a tropical climate and under the Köppen climate classification it has a semi-arid climate ( BSwhg ), like most parts of the Australian tropics, it has two seasons: a dry season and a wet season.

Neue Helvetica uses a numerical design classification scheme, like Univers.

When first introduced into Victoria Police, the Leading Senior Constable was a classification not a rank, somewhat like " detective ".

While the placement of a variety like Alasha, which is under the cultural influence of Inner Mongolia but historically tied to Oirat, and of other border varieties like Darkhad would very likely remain problematic in any classification, the central problem remains the question of how to classify Chakhar, Khalkha, and Khorchin in relation to each other and in relation to Buryat and Oirat.

That he anticipated in any manner the inductive reasoning of the true scientific method cannot be contended ; his botanical studies did not lead him, like his contemporary Konrad von Gesner, to any idea of a natural system of classification, and he rejected with the utmost arrogance and violence of language the discoveries of Copernicus.
