Differbetween
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 an example of parallel evolution?
'Parallel evolution' occurs when independent species acquire similar characteristics while evolving together at the same time in the same ecospace. An example of parallel evolution is extinct browsing-horses and paleotheres.
Which is an example of convergent evolution?
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 very good example of parallel evolution?
Parallel evolution, the evolution of geographically separated groups in such a way that they show morphological resemblances. A notable example is the similarity shown by the marsupial mammals of Australia to the placental mammals elsewhere.
What causes parallel evolution?
The repeated and similar large-scale morphological evolutionary trends of distinct lineages suggest that adaptation by means of natural selection (functional constraints) is the major cause of parallel evolution, a very common phenomenon in extinct and extant lineages.
What are the 3 types of evolution?
shows the three main types of evolution: divergent, convergent, and parallel evolution.
What are the 6 types of evolution?
Terms in this set (6)
- Convergent Evolution. The evolution of similar features in independent evolutionary lineages.
- Divergent Evolution. When two or more species sharing a common ancestor become more different over time.
- Co-Evolution. ...
- Reverse Evolution. ...

- Macroevolution.
What is an example of convergence?
The definition of convergence refers to two or more things coming together, joining together or evolving into one. An example of convergence is when a crowd of people all move together into a unified group. A meeting place. ... A town at the convergence of two rivers.
How 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. ... Both species might have acquired the trait by descent from a common ancestor.
Are eyes convergent evolution?
Therefore, the eyes of humans and octopuses have been described as a typical example of convergent evolution (Fig. 2; Brusca and Brusca 1990; Futuyma 1997).
What are 3 major sources of evidence for evolution?
Evidence for evolution
- Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
- Molecular biology. DNA and the genetic code reflect the shared ancestry of life. ...
- Biogeography. ...
- Fossils. ...
- Direct observation.
Is warm blooded convergent evolution?
It arises independently by convergent evolution in more than one clade. For example, both mammals and birds are able to maintain a high constant body temperature (warm-blooded). However, the ancestors of each group did not share this character, so it must have evolved independently.
What is the difference between adaptive radiation and convergent evolution?
When organism leaves original niche and enter another (multiple) niche of different environments it undergoes changes to suit the new environment this is adaptive radiation. Convergent evolution is when different species of different lineage arrive in a niche and they change their body to suit common environment.
