What is convergent evolution?
: the independent development of similar traits or features (as of body structure or behavior) in unrelated or distantly related species or lineages that typically occupy similar environments or ecological niches The remarkable resemblance of these moths to hummingbirds is a case of convergent evolution.
What is 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.
What is convergent evolution and its example?
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 the difference between convergent and parallel evolution?
Strictly speaking, convergent evolution occurs when descendants resemble each other more than their ancestors did with respect to some feature. Parallel evolution implies that two or more lineages have changed in similar ways, so that the evolved descendants are as similar to each other as their ancestors were.
What is convergent evolution quizlet?
In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
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.
What is the difference between convergent and divergence?
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’s the difference between convergent and divergent and transform 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.
Which is the best example of convergent evolution quizlet?
Wings of bats, birds and insects are an example of convergent evolution. Each of these species split into a separate lineage, and independently, with no relation to any common ancestor they may or may not have shared, they developed wings.
Why does convergent evolution occur?
Convergent evolution is a process in biology. It occurs when two species from unrelated lines develop the same traits or features. This happens because they live in similar habitats, and have to develop solutions to the same kind of problems. Similarity in traits can occur in two ways.
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.
How are convergent and divergent evolution 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 the difference between divergent and convergent evolution?
Divergent Evolution: Divergent evolution is a process by which an interbreeding species diverges into two or more descendant species. Convergent Evolution: Both species live within the same environment. Divergent Evolution: The two species live in different environments than their ancestor.
Which of the following is an example of convergent evolution?
The development of the eye of vertebrates, cephalopods, and cnidarian is another example of convergent evolution. Divergent evolution is a process of developing two or more species from a common ancestor.
How does parallel evolution differ from divergent evolution?
Parallel evolution differs from divergent evolution in that when parallel evolution occurs two already different species end up with similar traits while in divergent evolution one species (or very closely related species) evolves into two distinct species due to the development of different unique traits within the species itself over time.
What does it mean for a species to be divergent?
Divergent evolution is when members of a species, or of closely related species, evolve different traits that allow them to be successful in a new environment or niche. This leads to new species being created. When scientists talk about species that are closely related, they often mean that the species share a recent common ancestor.
