Index Class (biology)

In biological classification, class (classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. [1]

Clade

A clade (from κλάδος, klados, "branch"), also known as monophyletic group, is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life".

Cladistics

Cladistics (from Greek κλάδος, cládos, i.e., "branch") is an approach to biological classification in which organisms are categorized in groups ("clades") based on the most recent common ancestor.

Dog

The domestic dog (Canis lupus familiaris when considered a subspecies of the gray wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore.

Domain (biology)

In biological taxonomy, a domain (Latin: regio), also superkingdom or empire, is the highest taxonomic rank of organisms in the three-domain system of taxonomy designed by Carl Woese, an American microbiologist and biophysicist.

Ernst Haeckel

Ernst Heinrich Philipp August Haeckel (16 February 1834 – 9 August 1919) was a German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including anthropogeny, ecology, phylum, phylogeny, and Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny.

Ernst Mayr

Ernst Walter Mayr (5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists.

Family (biology)

In biological classification, family (familia, plural familiae) is one of the eight major taxonomic ranks; it is classified between order and genus.

Flowering plant

The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approximately 13,164 known genera and c. 295,383 known species.

France

France, officially the French Republic (République française), is a sovereign state whose territory consists of metropolitan France in Western Europe, as well as several overseas regions and territories.

Genus

A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.

Georges Cuvier

Jean Léopold Nicolas Frédéric, Baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology".

Joseph Pitton de Tournefort

Joseph Pitton de Tournefort (5 June 1656 – 28 December 1708) was a French botanist, notable as the first to make a clear definition of the concept of genus for plants.

Kingdom (biology)

In biology, kingdom (Latin: regnum, plural regna) is the second highest taxonomic rank, just below domain.

Life

Life is a characteristic that distinguishes physical entities that do have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate.
