Scientific classification Scientific classification The All Species Foundation seeks to catalog all species on Earth by 2025. It begun in 2001 as a spinoff of the Long Now Foundation. ...more on Wikipedia about "All Species Foundation"
Taxonomy, sometimes alpha taxonomy, is the science of finding, describing and naming organisms, thus giving rise to taxa. ...more on Wikipedia about "Alpha taxonomy"
Biota or Vitae is the superdomain that categorizes life. It is composed of the domains eukaryota, prokaryota, and acytota/ aphanobionta/ virus. ...more on Wikipedia about "Biota (taxonomy)"
Crown eukaryotes are a group of organisms found at the top of the phylogenetic tree of modern biology. They are multicellular and macroscopic lifeforms that have eukaryotic cells and represent the majority of the biomass of the planet while accounting for less than 1% of the genetic diversity. ...more on Wikipedia about "Crown eukaryotes"
In biology, a cryptic species complex is a group of species that satisfy the scientific definition of species — that is, they are reproductively isolated from each other — but which are anatomically indistinguishable. The individual species within the complex can only be separated using methods from molecular genetics such as DNA barcoding. ...more on Wikipedia about "Cryptic species complex"
In biology, the equivalent of a phylum in the plant or fungi kingdom is called a division. ...more on Wikipedia about "Division (biology)"
In biology, a domain (also superregnum, superkingdom, or empire) is the top-level grouping of organisms in scientific classification, higher than a kingdom. ...more on Wikipedia about "Domain (biology)"

English names for organisms arise from a variety of different sources. Although in biology, all species must be assigned a scientific name when newly described, in order to comply with the requirements of the International Code of Zoological Nomenclature, no such requirement exists in respect of English names. However, many scientists today, particularly when describing species in "popular" groups such as birds, assign a unique English name, in addition to the scientific name. At the other extreme, many species' English names have arisen through tradition. ...more on Wikipedia about "English names for organisms"
Evolutionary taxonomy or evolutionary systematics seeks to classify organisms using a combination of phylogenetic relationship and overall similarity. It differs from strict cladism where all taxa in a classification always should include all descendants of a single ancestral node. It thus allows for paraphyletic taxa. As evolutionary systematicists define terms, paraphyletic taxa are monophyletic too, in the sense that they derive from a single common ancestor, just not holophyletic, meaning that all descendants are included (which is monophyletic according to the cladistic definition). ...more on Wikipedia about "Evolutionary taxonomy"
In biological classification, family is one of the most important ranks, next only to species and genus. See: ...more on Wikipedia about "Family (biology)"
In biology, a genus (plural genera) is a taxonomic grouping. That is, in the classification of living organisms, a genus is considered to be distinct from other such genera. A genus has one or more species: if it has more than one species these are likely to be morphologically more similar than species belonging to different genera. ...more on Wikipedia about "Genus"
Incertae sedis—"of uncertain position (seat)"—is a term used to define a taxonomic group where its broader relationships are unknown or undefined. ...more on Wikipedia about "Incertae sedis"
In taxonomy, inclusion is the process whereby two species that were believed to be distinct are found in fact to be the same and are thus combined as one species. Which name is kept for this unified species is sometimes a cause of debate, but generally it is the earlier-named one, and the other species is said to be "included" within this one. ...more on Wikipedia about "Inclusion (taxonomy)"
In biology, a kingdom or regnum is the top-level, or nearly the top-level, taxon of organisms in scientific classification. Originally two kingdoms were distinguished: the Animalia for animals, and the Vegetabilia or Plantae for plants. Early authors also treated minerals in a third kingdom Mineralia. Each kingdom was divided into classes, later grouped into phyla for animals and divisions for plants. More recently, various other kingdoms have been created, and the ideal number and delineations are not settled. ...more on Wikipedia about "Kingdom (biology)" Everybody should like http://www.shortopedia.com
Linnaean taxonomy is a phrase used for the scientific classification widely used in the biological sciences. The underlying structure of the system was developed by Carolus Linnaeus, but its modern form is far more complex to adapt to advances in biology. ...more on Wikipedia about "Linnaean taxonomy"
Monotypic refers to a taxonomic group with only one subgroup at the next (smaller) taxonomic level, for example, a monotypic genus has only one species. Conversely, one can say that the contained group is monotypic within the larger group; a genus monotypic within a family. ...more on Wikipedia about "Monotypic"
A pathovar is a bacterial strain or set of strains with the same or similar characteristics, that is differentiated at infrasubspecific level from other strains of the same species or subspecies on the basis of distinctive pathogenicity to one or more plant hosts. ...more on Wikipedia about "Pathovar"
In biology, phenetics, also known as numerical taxonomy, is an attempt to classify organisms based on overall similarity, usually in morphology or other observable traits, regardless of their phylogeny or evolutionary relation. ...more on Wikipedia about "Phenetics"
Phylum ( plural: phyla) is a taxon used in the classification of life, adopted from the Greek phylai the clan-based voting groups in Greek city-states. (Although the International Code of Botanical Nomenclature allows the use of the term "Phylum", the term " Division" is almost always used by botanists.) Phyla represent the largest generally accepted groupings of animals and other living things with certain evolutionary traits, although the phyla themselves may sometimes be grouped into superphyla (e.g. Ecdysozoa with eight phyla, including arthropods and roundworms, and Deuterostomia with the echinoderms, chordates, hemichordates and arrow worms). ...more on Wikipedia about "Phylum"
Polytypic refers to a taxonomic group with more than one subgroup at the next (smaller) taxonomic level. ...more on Wikipedia about "Polytypic"
The term race referring to humans is commonly used to distinguish a population of humans from other populations; the biological term race does however not apply to the differences inside the race homo sapiens sapiensis. The most widely used human racial categories are based on visible traits (especially skin color and facial features), genes, and self-identification. Conceptions of race, as well as specific racial groupings, vary by culture and time and are often controversial due to their impact on social identity and hence identity politics. ...more on Wikipedia about "Race"

In biology, a race is any inbreeding group, including taxonomic subgroups such as subspecies, taxonomically subordinate to a species and superordinate to a subrace and marked by a peculiar profile of latent factors of hereditary traits. ...more on Wikipedia about "Race (biology)"
In biology, ring species present an interesting problem for those who seek to divide the living world into discrete species. ...more on Wikipedia about "Ring species"
Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. Modern classification has its roots in the system of Carolus Linnaeus, who used comparative anatomy to group species according to shared physical characteristics. These groupings have been revised since Linnaeus to improve consistency with the Darwinian principle of common descent. Molecular systematics, which uses genomic DNA analysis, has driven many recent revisions and is likely to continue to do so. Scientific classification belongs to the science of taxonomy or biological systematics. ...more on Wikipedia about "Scientific classification"
