Porzana Menehune
''Porzana'' is a genus of birds in the crake and rail family, Rallidae. Its scientific name is derived from Venetian terms for small rails. The spotted crake (''P. porzana'') is the type species. Taxonomy The genus ''Porzana'' was erected by the French ornithologist Louis-Pierre Vieillot in 1816 with the spotted crake (''Porzana porzana'') as the type species. The genus unites the typical "crakes" found essentially anywhere in the world except desert and polar regions. It contains 3 living species. In addition, a large number of prehistorically extinct species known only from fossil or subfossil remains have been discovered. The genera ''Coturnicops'', ''Crex'' (including ''Crecopsis'') and ''Laterallus'' have been suggested to be closely related. However, molecular phylogenetic analyses have confirmed the suspicion, raised in the late 20th century in the first cladistic studies of morphology, that the "genus" ''Porzana'' is rather an evolutionary grade, consisting of an ass ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Laterallus
''Laterallus'' is a genus of birds in the rail family Rallidae. These small, relatively short-billed terrestrial rails are found among dense vegetation near water in the Neotropics, although a single species, the black rail, also occurs in the United States. The genus was erected by the English zoologist George Robert Gray in 1855 with the rufous-sided crake (''Laterallus melanophaius'') as the type species. The genus name is a portmanteau of ''Rallus lateralis'', a synonym of the binomial name for the rufous-sided crake. The authors of a molecular genetic study published in 2019 proposed that the yellow-breasted crake, the dot-winged crake, and the flightless Inaccessible Island rail should be moved to this genus. Species The genus contains 13 species: *Black-banded crake, ''Laterallus fasciatus'' *Rufous-sided crake, ''Laterallus melanophaius'' *Rusty-flanked crake, ''Laterallus levraudi'' *Ruddy crake, ''Laterallus ruber'' *White-throated crake, ''Laterallus albigularis'' *Gr ...

Pardirallus
''Pardirallus'' is a genus of bird in the family Rallidae. It contains three species native to marshland areas of Southern, Central America and the Caribbean, although fossil evidence indicates they once ranged north to what is now Idaho. They are 25–38 cm long and have a long greenish bill and reddish legs. The spotted rail is blackish-brown with white markings while the other two are brown above and dark grey below. The genus ''Pardirallus'' was erected by the French naturalist Charles Lucien Bonaparte in 1856 with the spotted rail (''Pardirallus maculatus'') as the type species. The generic name combines the Ancient Greek ''pardos'' meaning "leopard" with the genus ''Rallus''. Species The genus contains three species : An fossil species, '' Pardirallus lacustris'', is known from the Late Pliocene of the Hagerman Fossil Beds of Idaho. It was formerly assigned to the genus ''Porzana'' upon its description in 1958 by Pierce Brodkorb and later to the genus ''Rallus ...

Plesiomorph
In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy, and synapomorphy, all mean a trait shared between species because they share an ancestral species. Apomorphic and synapomorphic characteristics convey much information about evolutionary clades and can be used to define taxa. However, plesiomorphic and symplesiomorphic characteristics cannot. The term ''symplesiomorphy'' was introduced in 1950 by German entomologist Willi Hennig. Examples A backbone is a plesiomorphic trait shared by birds and mammals, and does not help in placing an animal in one or the other of these two clades. Birds and mammals share this trait because both clades are descended from the same far distant ancestor. Other clades, e.g. snakes, lizards, turtles, fish, frogs, all have backbones and none are either birds nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Grade
A grade is a taxon united by a level of morphological or physiological complexity. The term was coined by British biologist Julian Huxley, to contrast with clade, a strictly phylogenetic unit. Definition An evolutionary grade is a group of species united by morphological or physiological traits, that has given rise to another group that has major differences from the ancestral condition, and is thus not considered part of the ancestral group, while still having enough similarities that we can group them under the same clade. The ancestral group will not be phylogenetically complete (i.e. will not form a clade), so will represent a paraphyletic taxon. In order to fully understand evolutionary grades, one must first get a better understanding of Phylogenetics, defined as "''In biology, is the study of the evolutionary history and relationships among individuals or groups of organisms (e.g. species, or populations). These relationships are discovered through phylogenetic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...
