Which is the best definition of convergent evolution?
It is the independent evolution of features that are similar in species spanning over different eras. This evolution produces analogous structures having similar functions or forms. However, they are not seen in the last common ancestor of those units.
Which is the best 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.Nov 1, 2019
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.
What is convergent evolution describe an example?
A widespread example of convergent evolution is the evolution of wings and powered flight in birds, bats and (now extinct) pterosaurs, each of which belong to a different class of organism and therefore have very distant common ancestors.Apr 28, 2017
What is convergent evolution state one example?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.Nov 1, 2019
Which best defines the term divergent evolution?
Divergent evolution is commonly defined as what occurs when two groups of the same species evolve different traits within those groups in order to accommodate for differing environmental and social pressures.
Which best defines the term divergent evolution quizlet?
Which BEST defines the term divergent evolution? A A process through which new species evolve from the interbreeding of two closely-related species.
What is meant by divergent evolution?
The process by which different organisms having common ancestors develop different traits or characteristics to adapt to the changing environmental conditions and needs is known as divergent evolution.
What is divergent evolution caused by?
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.Jun 7, 2021
What is divergent speciation?
Divergent speciation
Once interbreeding ends, two processes cause the isolated group to become different from the parent population: 1) Genetic variation occurs independently in the two groups. Lack of interbreeding prevents sharing of these independent genetic variations.
