Classic examples of divergence in nature are the adaptive radiation of the finches of the Galapagos or the coloration differences in populations of a species that live in different habitats such as with pocket mice and fence lizards.
What is divergence biology?
Supplement. In evolutionary biology, divergence pertains to an evolutionary process wherein a population of an inbreeding species diverges into two or more descendant species that have become more and more dissimilar in terms of forms and structures. This divergence results from their adaptation to their environment.
What is convergence and divergence biology?
Convergent evolution is when two species with different ancestral origins develop similar characteristics, while divergent evolution refers to when two species diverge from a common ancestor and develop different characteristics.
What does the word divergence mean?
Definition of divergence
1a : a drawing apart (as of lines extending from a common center) b : difference, disagreement.
What’s the difference between convergent and divergent?
Convergent plates converge, or come together. … Divergent plates diverge, or go away from each other. The plates pull away from each other, causing lava to spew out and develop new land. Earthquakes are caused by movement among the tectonic plates.
What is divergent evolution example?
In divergent evolution, two or more distinct species share a common ancestor from which they diverged. A common example is a modern elephant and woolly mammoth. They share a common ancestor and yet evolved into two different species. Another example is the dog, the wolf, and the fox.
What is divergent evolution Class 12?
The process in which two or more related species become more and more dissimilar is known as divergent evolution. … Another example of divergent evolution is the organisms having 5 pentadactyl limbs like the humans, bats and whales. They all have evolved from a common ancestor.
What is divergence a result of?
Divergent evolution is usually a result of diffusion of the same species to different and isolated environments, which blocks the gene flow among the distinct populations allowing differentiated fixation of characteristics through genetic drift and natural selection.
What causes divergence?
Divergence occurs when a stronger wind moves away from a weaker wind or when air streams move in opposite directions. When divergence occurs in the upper levels of the atmosphere it leads to rising air.
What are analogous organs?
The organs which have different anatomy but perform similar functions are called as analogous organs. They have different origin. For example, wings of insects and birds. Sweet potatoes and potatoes both have the same function of food storage but have different origin.
What is divergent evolution Class 10?
Meaning. When one or more different species evolve similarities in their characteristics and functions because of adaptations in an environment. When an ancestral species diverges into multiple different species, ultimately giving rise to new species.
What are divergent and convergent evolutions?
Divergent evolution occurs when two separate species evolve differently from a common ancestor. … Convergent evolution occurs when species have different ancestral origins but have developed similar features. A good example of convergent evolution is the similarities between the hummingbird and the hummingbird moth.
What is the divergence of a function?
Divergence measures the change in density of a fluid flowing according to a given vector field.
What is divergence in electromagnetic theory?
The Divergence of a vector field is a measure of the net flow of the flux around a given point. It is a basic term and used in many terminologies of Electromagnetics.
What is an example of a convergent?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. … Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.
What is divergent and convergent boundaries?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What is a divergent boundary?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
What is the divergence of a species?
Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there isn’ …
How does divergent evolution occur?
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’s another name for divergent evolution?
Divergent evolution | Convergent evolution |
---|---|
Caused by environmental changes, migration | Caused by environmental changes |
Another name for divergent evolution is divergent selection | Also called convergence |
Example: Darwin’s finches | Example: wings of insects, birds, and bats |
What is difference between homologous and analogous?
Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. … The wings of a butterfly and the wings of a bird are analogous but not homologous.
What are some examples of convergent and divergent evolution?
Convergent Evolution | Divergent Evolution |
---|---|
Few examples of convergent evolution are: Wings of insects, birds, bats The streamlined body of dolphins and shark | Darwin finches are an example of divergent evolution. |
What does divergence mean in geography?
A BROAD AREA WHERE two tectonic plates are colliding is a zone of convergence. An area where plates are moving apart is a zone of divergence.
What does diverge mean in physics?
the act, fact, or amount of diverging: a divergence in opinion. (in physics, meteorology, etc.) the total amount of flux escaping an infinitesimal volume at a point in a vector field, as the net flow of air from a given region.
How is divergence calculated in biology?
The time of divergence is then calculated by dividing half that distance (in nucleotides) by the mutation rate (t = d/2 ÷ μ).
What is a divergent view?
Divergent things are different from each other. [formal] Two people who have divergent views on this question are George Watt and Bob Marr. Synonyms: different, conflicting, differing, disagreeing More Synonyms of divergent.
How do you understand divergence?
Divergence is when the price of an asset is moving in the opposite direction of a technical indicator, such as an oscillator, or is moving contrary to other data. Divergence warns that the current price trend may be weakening, and in some cases may lead to the price changing direction.
How fast does divergent occur?
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
What is analogy biology?
analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
What are analogous organs Class 12?
Hint: Analogous organs are those organs that do not have the same origin but their function is the same. The origin of homologous organs is the same but their functions are different.
What are two analogous organs examples?
Example of analogous organ is the wings of the insect and the wings of the bird. The structure of wings of the bird has bones covered by flesh, skin, and feathers. Whereas the wings of insect is an extension of integument.
What is convergent evolution Class 12?
Convergent evolution is the process when different structures of different origin evolve to have the same function and have similarity.
How are convergent and divergent similar?
Similarities Between Convergent and Divergent Evolution
Both convergent and divergent evolution have contributed to the development of present organisms from the past organisms. Both convergent and divergent evolution generate variation, aiding species to perform their niche in the environment.
What is divergent evolution and adaptive radiation?
Adaptive radiation is a type of divergent evolution where a group of organisms quickly diverges into new species. … This process gets the name ‘radiation’ because new species radiate from a common ancestor. This tends to occur when organisms move into a new environment with a lot of available opportunities.
What is the difference between divergence and curl?
Divergence measures the “outflowing-ness” of a vector field. If v is the velocity field of a fluid, then the divergence of v at a point is the outflow of the fluid less the inflow at the point. The curl of a vector field is a vector field.
What is curl and divergence?
Roughly speaking, divergence measures the tendency of the fluid to collect or disperse at a point, and curl measures the tendency of the fluid to swirl around the point. Divergence is a scalar, that is, a single number, while curl is itself a vector.
Why is the divergence of a curl zero?
The curl of a field measures its circulation. Think of lines curving in various ways and closing on themselves without meeting any other lines. The circulation carries no sources or sinks, so the divergence of a curl is necessarily 0.
