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.
Which of the following is example of convergent evolution?
Flippers of dolphins and penguins are examples of convergent evolution.
Are there instances of convergent evolution of paired appendages?
The flipper forelimbs of marine mammals (cetaceans, pinnipeds, and sirenians) are a classic example of convergent evolution.
What are the similar species with different characteristics?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated.
What traits are the result of convergent evolution?
Convergent evolution: Convergent evolution occurs when two organisms that lack a recent common ancestor end up more and more alike as they adapt to a similar ecological niche. The organisms have convergent phenotypes, and their similar structural forms are called analogous structures (such as bird wings and bat wings).
What happens in convergent evolution?
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.
How are traits produced by convergent evolution different from homologies?
Definition. Homology refers to the existence of shared ancestry between a pair of structures or genes in different taxa while convergent evolution refers to the independent evolution of similar features in species of different periods in the timeline.
Which of the following is best explained by convergent evolution?
Which one of the following statements best describes this concept? Convergent evolution occurs when two species living in different areas evolve similarities through natural selection acting on those characteristics.
What causes convergent evolution?
Convergent evolution at the genetic level can result from one of three processes: first, evolution by mutations that occurred independently in different populations or species; second, evolution of an allele that was polymorphic in a shared ancestral population; and third, evolution of an allele that was introduced …
When a similar trait occurs between two species that is a result of adaptive convergence It is said to be?
Convergent evolution is the process by which two species develop similar features despite not sharing a recent common ancestor. Evolutionary biologists explain these similar characteristics as the product of natural selection.
How does convergent evolution support evolution?
What happens in convergent evolution quizlet?
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.
Why is the ocean-continent convergence also called Cordilleran convergence?
Continent-Ocean Convergence is also called Cordilleran Convergence because this kind of convergence gives rise to extensive mountain systems. A cordillera is an extensive chain of mountains or mountain ranges. Some mountain chains in North America and South America are called cordilleras.
What happens at the Oceanic-continent convergence?
Ocean-Continent Convergence. When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone.
How are volcanoes formed at convergent plate boundaries?
At a convergent plate boundary, when one plate is oceanic, there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc. In this winter image from space, the volcanoes are covered with snow.
Which type of convergence gives rise to extensive mountain systems?
Continent-Ocean Convergence is also called Cordilleran Convergence because this kind of convergence gives rise to extensive mountain systems. A cordillera is an extensive chain of mountains or mountain ranges.
