Hylocharis
''Hylocharis'' is a genus of hummingbirds, in the family Trochilidae. It contains two species that are both found in South America. Taxonomy The genus ''Hylocharis'' was introduced in 1831 by the German naturalist Friedrich Boie. The type species was designated by the English zoologist George Robert Gray in 1840 as the rufous-throated sapphire. The genus name combines the Ancient Greek ''hulē'' meaning "woodland" or "forest" with ''kharis'' meaning "beauty". This genus formerly included additional species. A molecular phylogenetic study published in 2014 found that the genus ''Hylocharis'' was polyphyletic. In the revised classification to create monophyletic genera, species were moved to ''Chrysuronia'' and ''Chlorestes''. The genus now contains the following two species: * Rufous-throated sapphire (''Hylocharis sapphirina'') * Gilded sapphire The gilded sapphire (''Hylocharis chrysura''), also known as the gilded hummingbird, is a species of hummingbird in the "emeral ...

''Chlorestes'' is a genus of hummingbirds.

Chrysuronia
''Chrysuronia'' is a genus of hummingbirds in the family Trochilidae. Taxonomy The genus ''Chrysuronia'' was introduced in 1850 by the French naturalist Charles Lucien Bonaparte. Bonaparte did not specify a type species but this was designated as the golden-tailed sapphire in 1855 by George Robert Gray. The genus name is a portmanteau of the specific names of two synonyms of the golden-tailed sapphire: ''Ornismya chrysura'' Lesson, R, 1832 and ''Ornismia oenone'' Lesson, 1832. This genus formerly included only a single species, the golden-tailed sapphire. A molecular phylogenetic study published in 2014 found that the genera ''Amazilia'' and ''Lepidopyga'' were polyphyletic. In the revised classification to create monophyletic genera, ''Chrysuronia'' was broadened to include species that had previous been placed in ''Amazilia'', ''Hylocharis'' and ''Lepidopyga''. The genus now contains nine species: * Shining-green hummingbird (''Chrysuronia goudoti'') – formerly in ''Lepidop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''.

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
