The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium. The illicium is the detached and modified first three spines of the anterior dorsal fin. In most anglerfish species, the longest filament is the ...
Phylogeography is the study of the historical processes that may be responsible for the past to present geographic distributions of genealogical lineages. This is accomplished by considering the geographic distribution of individuals in light of genetics, particularly population genetics.
e. In biology, phylogenetics (/ ˌfaɪloʊdʒəˈnɛtɪks, - lə -/) [1][2][3] is the study of the evolutionary history of life using genetics, which known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology.
Phylogenesis (from Greek φῦλον phylon "tribe" + γένεσις genesis "origin") is the biological process by which a taxon (of any rank) appears. The science that studies these processes is called phylogenetics. [1][2][3][4][5] These terms may be confused with the term phylogenetics, the application of molecular - analytical methods (i.e ...
Phylogenomics. Phylogenomics is the intersection of the fields of evolution and genomics. [1] The term has been used in multiple ways to refer to analysis that involves genome data and evolutionary reconstructions. [2] It is a group of techniques within the larger fields of phylogenetics and genomics. Phylogenomics draws information by ...
According to FishBase about 34,800 species of fish had been described as of February 2022, [5] which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds. Fish species diversity is roughly divided equally between marine (oceanic) and freshwater ecosystems.
Reticulate evolution, or network evolution is the origination of a lineage through the partial merging of two ancestor lineages, leading to relationships better described by a phylogenetic network than a bifurcating tree. [1] Reticulate patterns can be found in the phylogenetic reconstructions of biodiversity lineages obtained by comparing the ...
The fanfin family, Caulophrynidae, takes its name from the genus Caulophryne.This name is a combination of caulis, which mean" stem", an allusion to the stem-like base of the illicium, with phryne, meaning "toad", a suffix commonly used in the names of anglerfish genera.
