What Is The Difference Between Convergent And Divergent Evolution


What Is The Difference Between Convergent And Divergent Evolution?

Whereas convergent evolution involves unrelated species that develop similar characteristics over time divergent evolution involves species with a common ancestor that change to become increasingly different over time.Nov 8 2020

What is difference between divergent and convergent?

Divergence generally means two things are moving apart while convergence implies that two forces are moving together. … Divergence indicates that two trends move further away from each other while convergence indicates how they move closer together.

What are the difference between convergent and divergent evolutions give example?

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 difference between convergent and divergent evolution quizlet?

Convergent Evolution: The process by which unrelated species become more similar as they adapt to the same kind of environment. Divergent Evolution: The process of two or more related species becoming more and more dissimilar.

What is convergent evolution and divergent evolution explain with examples?

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 difference between convergent plate and divergent plate?

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 convergent evolution and examples?

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 convergent evolution?

In evolutionary biology convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities. VLRs and TCRs/BCRs both serve as antigen receptors but are evolutionarily unrelated.

What is divergent evolution examples?

Galapagos finches are an example of divergent evolution. Through time the species evolved morphologically different traits. A prototype example of divergent evolution is Galapagos finches. … Thus they become a different species to their ancestors and what was once one species has diverged into two.

What is convergent evolution quizlet?

Convergent Evolution. The process whereby organisms not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

What is an example of divergent evolution quizlet?

Darwin’s finches are a clear and famous example of divergent evolution in which an ancestral species radiates into a number of descendant species with both similar and different traits to Adapt and Inhabit the surrounding Conditions.

What are 2 examples of convergent evolution?

Examples of convergent evolution include the relationship between bat and insect wings shark and dolphin bodies and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution but homologous structures do not.

What is the difference between divergent evolution and adaptive radiation?

Adaptive radiation is the diversification of a species into different forms in order to adapt to different environmental conditions for their survival. Divergent evolution is the accumulation of differences between groups of organisms that lead to the creation of new different varieties of species.

Is convergent evolution homologous or analogous?

Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures‘. They are contrasted with ‘homologous structures’ which have a common origin.

What causes convergent evolution?

Convergent evolution at the genetic level can result from one of three processes: first evolution by mutations that occurred independently in different populations or species second evolution of an allele that was polymorphic in a shared ancestral population and third evolution of an allele that was introduced …

What are the similarities and differences between convergent and divergent plate boundaries?

You must have at least 2 similarities and two differences. Divergent Plate Boundaries move away from each other while Convergent Plate Boundaries move toward each other. Convergent boundaries form earthquakes and volcanoes while divergent boundaries form sea floor spreading.

What is the difference between a divergent boundary and a convergent boundary Quizizz?

Oceanic plates separate from each other at a divergent plate boundary at the bottom of the ocean. … Continental crust and continental crust come toward each other at a convergent plate boundary.

What do you mean by convergence and divergence plates?

The Earth’s lithosphere which includes the crust and upper mantle is made up of a series of pieces or tectonic plates that move slowly over time. A divergent boundary occurs when two tectonic plates move away from each other. … When two plates come together it is known as a convergent boundary.

Are birds and bats divergent evolution?

Bird bat and pterosaur wings are analogous structures but their forelimbs are homologous sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution where related species evolve different traits.

Are marine mammals an example of convergent or divergent evolution?

Marine mammals from different mammalian orders share several phenotypic traits adapted to the aquatic environment and therefore represent a classic example of convergent evolution.

Are sharks and dolphin examples of convergent evolution or divergent evolution?

Both dolphins and sharks swim after prey in the ocean. … We know that dolphins and sharks are not closely related and they didn’t inherit their similar body shapes from a common ancestor. Their streamlined bodies dorsal fins and flippers are the result of convergent evolution.

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.

Which best defines the term divergent evolution quizlet?

divergent evolution. a type of evolution in which organisms are thought to have the same ancestor but separated over time.

What is the relationship between convergent divergent evolution and homologous analogous traits?

Convergent evolution shows how species have evolved separately but have similar (analogous) structures. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.

Which of the following is an example of divergence?

An example of divergence is when a couple split up and move away from one another. An example of divergence is when a teenager becomes an adult. An example of divergence is when your political views go against the party in which you are registered.

What is the best example of convergent evolution quizlet?

An example of convergent evolution are the wings of insects birds and bats. They all serve the same function and are similar in structure but evolved independently.

What is Convergent quizlet?

convergent boundary. the boundary formed by the collision of two lithospheric plate. divergent boundary. the boundary between two tectonic plates that are moving away from each other. transform boundary.

How does divergent evolution occur quizlet?

When does divergent evolution occur? Occurs when gene flow between two distinct populations is blocked which results in differentiated accumulation of characteristics through genetic drift and natural selection.

Where do divergent plates occur?

mid-ocean oceanic ridges

Divergent boundaries are spreading boundaries where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).

Which is the best example of convergent evolution?

In cultural evolution convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. An example of convergent evolution is the similar nature of the flight/wings of insects birds pterosaurs and bats.

Are birds and butterflies convergent or divergent?

In the case of wings of birds and butterflies the physiological appearance or function is the same – meant for flying but the anatomical structure when observed is completely different. Such structures are known as analogous structures and they indicate lack of common ancestry. This is Convergent evolution.

Why adaptive radiation is called convergent evolution?

Adaptive radiation if occurs twice in a geographically isolated area will have a similar result that is the evolved species will have similar adaptations suitable for the area. Hence it will be a case of convergent evolution.

Are Penguins examples of convergent evolution?

Convergent evolution is this phenomenon where similar characters evolve independently in multiple lineages. … Cormorants penguins puffins and gannets each with minimal relatedness to the others have evolved to have a “pygostyle” tail which is straight and elongated.
