What is a cline anthropology?

What are clines? In anthropology we talk about clinal variation. Cline is a term that was devised by the biologist Julian Huxley to represent a geographical gradient in a particular trait across a species.

What is a cline in evolution?

A cline is a geographic gradient in the frequency of a gene, or in the average value of a character. It can also arise if two forms are adapted to different environments separated in space and migration (gene flow) takes place between them. … Geographic variation normally exists in the formof a continuous cline.

What is cline in zoology?

In biology, a cline (from the Greek κλίνειν klinein, meaning to lean) is a measurable gradient in a single character (or biological trait) of a species across its geographical range. …

What is cline theory?

Classical cline theory interprets clines as speciation processes in two stages: (1) smooth clines, typical of species with no marked subspecies, and (2) stepped clines, characteristic of species with marked subspecies, separated by hybrid zones, where the clines are steeper than within the areas of the subspecies.

What is a cline quizlet?

Cline is a gradual change in characteristics from one population to another. Specific traits following a geographical continuum are called a cline. No races only clines.

What is an example of a cline in biology?

A cline is the specific set of traits in a population of a given species that have been influenced by the local environment. For example, a population of warm-blooded animals that lived in a cooler climate closer to the North Pole would have larger bodies, allowing them to better conserve heat.

What is cline linguistics?

A cline is a scale of language items that goes from one extreme to another, for example, from positive to negative, or from weak to strong. … However, a learner’s ability to use a cline does not mean that they can use the target language in context.

What are Clines in genetics?

A cline is a gradient of a phenotypic or genetic character within a single species. The geographic distances across which characters shift can range from meters to thousands of kilometers.

What is cline Give 5 example?

freezing, cold, chilly, nippy, cool, mild, warm, hot, boiling, sweltering. blue, low, depressed, miserable, sorrowful.

What are species concepts?

Definition. Species are groups of actually or potentially interbreeding populations which are reproductively isolated from other such groups. … Thus, under the biological species concept, species are simultaneously a reproductive community, a gene pool, and a genetic system.

What is a cline and how does it help us understand human diversity?

Clines are gradations in biological features over geographic space. They refer to continuous degrees of difference in either phenotype or genotype across or within human populations. A given cline consists of the gradient in frequency of a single trait over space.

What is a cline and why is it important for our understanding of human variation?

A cline is a gradation in the frequency of an allele/trait between populations living in different geographic regions. In order to study human traits that are clinally distributed, it is often required to perform genetic testing to uncover the true frequencies of an allele or trait across a certain geographic space.

Why does the existence of a cline suggest natural selection?

The existence of a cline suggests natural selection because of the close association between the environmental variable and the frequency of the allele. 7. … These mutations provide the raw material from which new traits may arise and be selected.

What are ring species in evolution?

A ring species is a situation in which two populations which do not interbreed are living in the same region and connected by a geographic ring of populations that can interbreed.

What phenotype means?

The term phenotype refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What is a cline Group of answer choices?

What is a cline? the slope of a mountain where a population lives. the degree to which a mutation varies across a population. an environment that is isolated from nearby areas.

What is an example of a cline quizlet?

A cline is a graph that shows geographic variation in population. For example a cline could show the frequency of a certain allele in a fish population based on temperature in the environment. Discuss 3 sources of genetic variation.

Which is a major contributor to the success of our species?

Which is a major contributor to the success of our species? Answer is (a) human adaptability. Rationale for rejecting b,c,d options: Humans do not have a high fecundity, they can give birth to 1-3 offspring on an average. The skin tone variation is an adaptation that is based on the geography.

What is divergent evolution?

What Is Divergent Evolution? Divergent evolution occurs when a population of animals or plants is split into two groups by a geographic barrier (for instance, a body of water or a migration to a new area), causing each group to develop different traits under their respective selective pressures and natural selection.

What is the biological definition of race?

(1) A group or population of humans categorized on the basis of various sets of heritable characteristics (such as color of skin, eyes, and hair). (2) A descent from a common heritage, ancestor, breed or stock.

What is the difference between race and Cline?

is that race is (biology) a population geographically separated from others of its species that develops significantly different characteristics; (an informal term for) a subspecies while cline is (biology) a gradation in a character or phenotype within a species or other group.

What is a Cline for kids?

In biology, a cline, or ‘ecocline’, describes a series of connected populations in a species. These populations show a continuous gradient of traits and genetics. He defined a cline as a species whose members fall into a series of sub-species with continuous change in characters over a geographical area. …

What is the importance of word Cline?

Word Cline helps students to build, refine and use new vocabulary as they generate synonyms and discuss connotations and nuances of meaning. They generate words with similar meaning and arrange them to show a graduating intensity, according to a given criterion.

What is Cline activity?

ACTIVITY – WORD CLINE A word cline is a graded sequence of words whose meanings span across a continuum of meanings on a sloping line. This activity expands students’ vocabulary and to discover shades of meaning between words. It is a great way to introduce language embedded within a genre.

What are Nonconcordant traits?

A common example of a pair of nonconcordant traits is skin color and height. On both an individual and group level, skin color is independent of height (and height is reciprocally independent of skin color). As skin colors become lighter or darker, heights do not change in a predictable, dependent, or concordant way.

What is racial determinism?

Racial essentialism is the concept that people of different racial and ethnic groups possess specific traits and behaviors unique to their group. Biological determinism is the belief that race is a genetic reality that regulates how we behave.

What is a Clinal distribution?

Genetically inherited traits often have a clinal distribution. That is to say there is a continuous, progressive gradation moving from one geographic region to another. … Such patterns can result when selective pressures differ from one region to another and when people mate mostly with their immediate neighbors.
