Convergent evolution is when different organisms independently evolve similar traits. ... For example, sharks and dolphins look relatively similar despite being entirely unrelated.

What is it called when 2 unrelated organisms look alike?
Convergent. When two unrelated organisms look alike (sharks and dolphins) Biodiversity. Refers to the variety of living things.
Why are some organisms that are not closely related look similar?
Misleading Appearances
Similarly, unrelated organisms may be distantly related, but appear very similar. This usually happens because both organisms developed common adaptations that evolved within similar environmental conditions.
What is it called when one species evolves into many?
Adaptive radiation is the process by which one species evolves into two or more species. This occurs as a result of different populations becoming reproductively isolated from each other, usually by adapting to different environments.
What has different shaped shells depending on an island?
Galápagos tortoises have differently shaped shells depending on which island they inhabit.
What is an example of divergent evolution?
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. Charles Darwin's Beagle voyage led him to conclude that the finches diverged from their descendant species.
What's an example of artificial selection?
Dog breeding is another prime example of artificial selection. ... Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs.
What is an example of comparative anatomy?
A common example of comparative anatomy is the similar bone structures in forelimbs of cats, whales, bats, and humans. All of these appendages consist of the same basic parts; yet, they serve completely different functions. ... One explanation for the forelimbs' similar composition is descent with modification.
What is it called when two taxa share similar traits that their common ancestor did not have?
Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.
How is it possible for two species that look similar to be less related than two species who look completely different?
Homologous structures are similar in development, but may look very different on the outside. This typically happens because the two species are evolving in different pathways.
What is it called when an animal evolves to look like another animal?
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species.
What causes speciation?
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
What is meant by the term punctuated equilibrium?
: evolution that is characterized by long periods of stability in the characteristics of an organism and short periods of rapid change during which new forms appear especially from small subpopulations of the ancestral form in restricted parts of its geographic range also : a theory or model of evolution emphasizing ...
What name is given to two structures that are similar in structure but have different functions?
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. ... However, their forelimbs now have different functions.
What is evolutionary pattern?
The course Evolutionary Patterns turns the perspective from Evolutionary Processes around and focuses on how the evolutionary history is manifested in patterns that can be observed in and among organisms, and how these patterns can be detected and analysed to let us draw conclusions about the causes and the underlying ...
What is the study of the similarities and differences between organisms called?
Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies. Both provide evidence for evolution.
