Which of the following is an example of convergent evolution
Andrew White An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats. All four serve the same function and are similar in structure, but each evolved independently. Some aspects of the lens of eyes also evolved independently in various animals.
Which is an example of convergent evolution?
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 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.
Which would be an 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.What is an example of convergent and divergent evolution?
Examples. Convergent Evolution: Ostriches, rheas, and emus are examples of convergent evolution. Divergent Evolution: Dinosaurs, Darwin’s finches, and forelimb structures of vertebrates are examples of divergent evolution.
What is convergent evolution give an example class 12?
Complete answer: Convergent evolution describes the independent evolution of comparable features in species of various lineages. Though sharks and dolphins have similar bodies but are only distantly related. Sharks are fish and dolphins are mammals.
What is an example of convergent evolution in mammals?
Mammals. Several groups of ungulates have independently reduced or lost side digits on their feet, often leaving one or two digits for walking. That name comes from their hooves, which have evolved from claws several times. For example, horses have one walking digit and domestic bovines two on each foot.
Why are birds an example of convergent evolution?
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence. The two groups have powered flight, evolved independently. Their wings differ substantially in construction.Which of the following is an example of convergent evolution and analogous structures *?
Bat and pterosaur wings are an example of analogous structures, while the bat wing is homologous to human and other mammal forearms, sharing an ancestral state despite serving different functions.
Which of the following pairs are examples of analogous structures?Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Plants and other organisms can also demonstrate analogous structures, such as sweet potatoes and potatoes, which have the same function of food storage.
Article first time published onWhat are examples of vestigial structures quizlet?
Vestigial structures are structures in animals that are reduced in size to where they are just traces of homologous structures in other species. Examples would include the human tail bone, certain bones in whales and the human appendix.
What happens in divergent evolution quizlet?
Terms in this set (9) 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. … A pattern of evolution which similar traits arise in two or more unrelated species.
What is the meaning of divergent evolution?
Definition. Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period.
Which of the following best explains convergent evolution?
Convergent evolution occurs when two species living in different areas evolve similarities through natural selection acting on those characteristics. … structures of animals that have difference appearances and functions but seem to have evolved from the same body part in a common ancestor.
What is convergent evolution Khan Academy?
Instead, some physical similarities are analogous: they evolved independently in different organisms because the organisms lived in similar environments or experienced similar selective pressures. This process is called convergent evolution. (To converge means to come together, like two lines meeting at a point.)
Are Darwin's finches example of convergent evolution?
Darwin’s Finches are an example of. A. Convergent evolution. … All species of Darwin’s finches were closely associated with each other, having derived recently (in geological terms) from a common ancestor.
Are sharks and dolphins convergent evolution?
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 does convergent evolution tell us?
In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
What is convergent evolution Class 10?
In Convergent evolution, widely different organisms evolve similar structures due to similar environmental habitat. Convergent evolution actually means distantly related groups converging together to perform same functions because of the demand of similar environment. Convergent evolution creates analogous structures.
What is convergent evolution Ncert?
Convergent evolution is the process when different structures of different origin evolve to have the same function and have similarity. … Many new species evolved, diverged, and adapted to occupy new habitats.
What is convergent evolution Byjus?

What is convergent evolution and divergent evolution?
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.
Why are the wolf and Tasmanian wolf considered examples of convergent evolution?
The thylacine and placental canids such as wolves, dogs and foxes, are perhaps the most striking example of convergent evolution. Through this process, distantly related animals can evolve similar forms in response to shared environmental challenges.
Are dolphins and sharks analogous or homologous?
SharksDolphinsskeleton made of cartilageskeleton made of bone
Are bats and butterflies convergent evolution?
Convergent evolution. A bat darting out of its cave at twilight. … In the case of bats, birds and butterflies — none of which share a common ancestor that flew — they all “converged” on the ability of flight as a useful trait in response to environmental stimuli and biological goals.
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.
How are birds and bats convergent evolution?
Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
What are analogous structures 3 examples?
- Bird, Insect and Bat Wings. …
- Fish and Penguin Fins/Flippers. …
- Duck and Platypus Bills. …
- Cacti and Poinsettia Plant Structures. …
- Crab and Turtle Shells. …
- Turtle and Bird Beaks. …
- Octopus and Human Eyes. …
- Shark and Dolphin Coloring.
What are the examples of analogous?
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. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it.
Which one of the following is an example of analogous organs?
Wings of birds and butterfly.
What are vestigial structures 3 examples?
Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds. Vestigial structures can become detrimental, but in most cases these structures are harmless; however, these structures, like any other structure, require extra energy and are at risk for disease.
