Pygsuia
''Pygsuia'' is a genus in the clade of Breviatea, which are Basal (phylogenetics), basal eukaryotes. This genus contains only one species, ''Pygsuia biforma'', which is known for its long Flagellum, flagella compared to other breviates. Etymology The genus name, ''Pygsuia'', is derived from a part of the University of Arkansas Arkansas Razorbacks football, Razorbacks sports cheer, which goes "''Wooo Pig Hog calling, Sooie''". This is because the species has a row of structures similar to those of actual Feral pig, razorbacks. "Pyg" in the genus name refers to pigs while also referencing the Latin term ''Pygmae'', as a nod to the organisms' small size. "Sui" in the genus name refers to the sound made by Hog calling, hog callers. As a consequence, the full genus name means "little pig" in mock Latin.

Breviatea
Breviatea, commonly known as breviate amoebae, are a group of free-living, amitochondriate protists with uncertain phylogenetic position. They are biflagellate, and can live in anaerobic (oxygen-free) environments. They are currently placed in the Obazoa clade. They likely do not possess vinculin proteins. Their metabolism relies on fermentative production of ATP as an adaptation to their low-oxygen environment. The lineage emerged roughly one billion years ago, at a time when the oxygen content of the Earth's oceans was low, and they thus developed anaerobic lifestyles. Together with Apusomonads, they are the closest relatives of the Opisthokonts, a group that includes animals and fungi. Characteristics Mitochondrion-related organelles Mitochondrion-related organelles (MROs) are organelles that evolved from a degradation of ancestral, fully functional mitochondria. Among Breviatea, MROs are present in '' Pygsuia'', '' Breviata'' and '' Subulatomonas''. In the cells of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...

Eukaryote
The eukaryotes ( ) constitute the Domain (biology), domain of Eukaryota or Eukarya, organisms whose Cell (biology), cells have a membrane-bound cell nucleus, nucleus. All animals, plants, Fungus, fungi, seaweeds, and many unicellular organisms are eukaryotes. They constitute a major group of Outline of life forms, life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority of the number of organisms, but given their generally much larger size, their collective global biomass is much larger than that of prokaryotes. The eukaryotes emerged within the archaeal Kingdom (biology), kingdom Asgard (Archaea), Promethearchaeati and its sole phylum Promethearchaeota. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes first emerged during the Paleoproterozoic, likely as Flagellated cell, flagellated cells. The leading evolutiona ...

Flagellum
A flagellum (; : flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores ( zoospores), and from a wide range of microorganisms to provide motility. Many protists with flagella are known as flagellates. A microorganism may have from one to many flagella. A gram-negative bacterium '' Helicobacter pylori'', for example, uses its flagella to propel itself through the stomach to reach the mucous lining where it may colonise the epithelium and potentially cause gastritis, and ulcers – a risk factor for stomach cancer. In some swarming bacteria, the flagellum can also function as a sensory organelle, being sensitive to wetness outside the cell. Across the three domains of Bacteria, Archaea, and Eukaryota, the flagellum has a different structure, protein composition, and mechanism of propulsion but shares the same function of providing motility. The Latin word means " whip" to describe its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hog Calling
Hog calling, or pig calling, is the art of making a call to encourage pigs to approach the caller. Competitions in hog calling are held. Calls To attract pigs (or family), the calls are based on four strategies: a male call to encourage territorial males to come to fight, a female call to encourage males to come to mate, a general call of dinner is served, and a piglet in distress call which works on adults. Aids to calling Calls are usually simple woodwind instruments, sometimes adapted from other hunting lures. Electronic devices are also available. Contests Hog calling contests are usually held in regions with pig farming. Rules may vary between competitions. There usually is a time limit of 30 seconds, but some festivals allow for longer time. In competitions where there is no set rule for the duration of the call, it can be a criterion for judgement, awarding more points for sustained loud calls. The contestants are also judged on creativity. The contestant should aim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Pig

It is named the domestic pig when distinguishing it from other members of the genus '' Sus''. Some authorities cons ... which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are sometimes used in the United States in reference to feral pigs or boar–pig hybrids. Definition A feral organism, feral pig is a domestic pig that has escaped or been released into the wild, and is living more or less as a wild animal, or one that is descended from such animals. Zoologists generally exclude from the ''feral'' category animals that, although captive, were genuinely wild before they escaped. Accordingly, Eurasian wild boar, released or escaped into habitats w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mock Latin
Dog Latin, or cod Latin, is a phrase or jargon that imitates Latin, often by what is referred to as "translating" English words (or those of other languages) into Latin by conjugating or declining them, as if they were Latin words. Dog Latin is usually a humorous device used for mocking scholarly seriousness. The term can also refer to a poor-quality attempt at writing genuine Latin. Origins and History The origins of Dog Latin can be traced back to early examples in literature. For example, Dog Latin predates Shakespeare, whose 1590s play, ''Love's Labour's Lost'', includes a reference to dog Latin: The term was also mentioned by Thomas Jefferson in 1815, indicating its use in scholarly and literary contexts: Examples * ''Illegitimi non carborundum'', interpreted as "Don't let the bastards grind you down." Offred, the protagonist of the novel ''The Handmaid's Tale'', finds a similar phrase scratched into the wall of her wardrobe: ''Nolite te bastardes carborundorum''. ...

Obazoa
Obazoa is a proposed sister clade of Amoebozoa (which together form Amorphea). The term Obazoa is based on the OBA acronym for Opisthokonta, Breviatea, and Apusomonadidae, the group's three constituent clades. Determining the placement of Breviatea and Apusomonadida and their properties is of interest for the development of the opisthokonts in which the main lineages of animals and fungi A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms.

The relationships among opisthokonts, breviates and apusomonads are not conclusively resolved (as of 2018), though Breviatea is usually inferred to be the most basal of the three lineages. The phylogeny of the Obazoa is shown in the cladogram. References {{Taxonbar, from=Q22087764 Amorphea taxa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
