Convergent evolution is the process by which two species develop similar features despite not sharing a recent common ancestor. ... By sharing similar ecological niches, the two unrelated species benefit from developing the same functional characteristics.

What is it called when two unrelated species look alike?
Image credit: Shutterstock) Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.
When unrelated species evolve similar characteristics?
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 it called when different species have similar structures?
Homologous structures are structures found in different species that have similar anatomical forms, resulting from a common ancestor.
What is it called when the same trait evolved in multiple different species?
Convergent evolution occurs in different species that have evolved similar traits independently of each other.
What does the term biogeography mean?
biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution. Earth's floral regions.
What is 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 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.
What is Molecular Systematics?
Molecular systematics is the use of molecular genetics to study the evolution of relationships among individuals and species. The goal of systematic studies is to provide insight into the history of groups of organisms and the evolutionary processes that create diversity among species.
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 do you mean by taxonomy?
Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world.
What is an example of homology?
An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.
What is analogous character?
The roles of analogous characters are similar.
The wings of a butterfly and a bird, for example, are comparable; they serve the same purpose.
What happens when two different and unrelated species face a similar problem?
Convergent evolution is the independent evolution of similar trait(s) in unrelated species. This usually happens because the species are living in similar (or the same) environments, so they evolve similar adaptations to face the same selective pressures.
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 analogous evolution?
In evolutionary biology, the meaning of analogous is “having similarities in functions but different evolutionary origins”. ... This is a kind of evolution in which organisms evolve structures that have the same functions despite their unrelated evolutionary ancestors.
