What are 2 examples of convergent evolution?
Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.
What is convergent evolution give an example?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.
Which is the best example of convergent evolution?
In cultural evolution, convergent evolution is the development of similar cultural adaptations to similar environmental conditions by different peoples with different ancestral cultures. An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats.
How do you know if evolution is convergent?
Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as ‘analogous structures’. They are contrasted with ‘homologous structures’, which have a common origin.
What is an analogous trait?
In morphology, analogous traits arise when different species live in similar ways and/or a similar environment, and so face the same environmental factors. When occupying similar ecological niches (that is, a distinctive way of life) similar problems can lead to similar solutions.
What is the description of convergent?
1 : tending to move toward one point or to approach each other : converging convergent lines a tropical cyclone characterized by convergent airflow. 2 : exhibiting convergence in form, function, or development …
What are the example of convergent?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
What are the examples of convergent?
3 Examples of Convergent Evolution
- Marine animals: Fish and dolphins are vastly different animals with different underlying DNA sequences and nervous systems.
- Flying animals: Birds, bats, and insects all developed wings via different evolutionary paths.
What is convergent 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.
What are Homoplastic traits?
adjective. (1) (evolutionary biology) Of, pertaining to, characteristic of, or exhibiting homoplasy. (2) (medicine) Of, or pertaining to the transplantation of tissue, organ, or parts derived from an individual to another of the same species; allogeneic.
What is convergent in simple words?
1 : tending to move toward one point or to approach each other : converging convergent lines a tropical cyclone characterized by convergent airflow.
What creates convergent?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
