Dialect continuum
A dialect continuum or dialect chain is a series of language varieties spoken across some geographical area such that neighboring varieties are mutually intelligible, but the differences accumulate over distance so that widely separated varieties may not be. This is a typical occurrence with widely spread languages and language families around the world, when these languages did not spread recently.
German dialects
German dialects are the various traditional local varieties of the German language. Though varied by region, those of the southern half of Germany beneath the Benrath line are dominated by the geographical spread of the High German consonant shift, and the dialect continuum that connects German to the neighboring varieties of Low Franconian (Dutch) and Frisian. The varieties of German are conventionally grouped into Upper German, Central German and Low German; Upper and Central German form the High German subgroup.
Dialect
Dialect (from Latin dialectus, dialectos, from the Ancient Greek word διάλεκτος, 'discourse', from διά, 'through' and λέγω, 'I speak') can refer to two distinctly different types of linguistic phenomena. One usage refers to a variety of a language that is a characteristic of a particular group of the language's speakers. Under this definition, the dialects or varieties of a particular language are closely related and, despite their differences, are most often largely mutually intelligible, especially if geographically close to one another in a dialect continuum.
Standard German
Standard High German (SHG), less precisely Standard German, or High German (Standardhochdeutsch, Standarddeutsch, Hochdeutsch or, in Switzerland, Schriftdeutsch) while referring to its regional origins and not to be confused with High German dialects, is the standardized variety of the German language used in formal contexts and for communication between different dialect areas. It is a pluricentric Dachsprache with three codified (or standardised) specific regional variants: German Standard German, Austrian Standard German and Swiss Standard German.
Spatial analysis
Spatial analysis is any of the formal techniques which studies entities using their topological, geometric, or geographic properties. Spatial analysis includes a variety of techniques using different analytic approaches, especially spatial statistics. It may be applied in fields as diverse as astronomy, with its studies of the placement of galaxies in the cosmos, or to chip fabrication engineering, with its use of "place and route" algorithms to build complex wiring structures.
Evolutionary biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. In a population, the genetic variations affect the phenotypes (physical characteristics) of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed onto their offspring.
Standard language
A standard language (also standard variety, standard dialect, and standard) is a language variety that has undergone substantial codification of grammar and usage, although occasionally the term refers to the entirety of a language that includes a standardized form as one of its varieties. Typically, the language varieties that undergo substantive standardization are the dialects associated with centers of commerce and government.
Heredity
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics. In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents.
K-means clustering
k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells. k-means clustering minimizes within-cluster variances (squared Euclidean distances), but not regular Euclidean distances, which would be the more difficult Weber problem: the mean optimizes squared errors, whereas only the geometric median minimizes Euclidean distances.
Evolutionary developmental biology
Evolutionary developmental biology (informally, evo-devo) is a field of biological research that compares the developmental processes of different organisms to infer how developmental processes evolved. The field grew from 19th-century beginnings, where embryology faced a mystery: zoologists did not know how embryonic development was controlled at the molecular level. Charles Darwin noted that having similar embryos implied common ancestry, but little progress was made until the 1970s.
