In the case of convergent evolution, several organisms converge/share a common environment. Such change assists in their survival and modifies the morphology or displays analogous organs. In the case of adaptive radiation, an organism comes out of its existing habitat and travels to a completely new environment .
What is the difference between convergent evolution and adaptive radiation?
In the case of convergent evolution, several organisms converge/share a common environment. Such change assists in their survival and modifies the morphology or displays analogous organs. In the case of adaptive radiation, an organism comes out of its existing habitat and travels to a completely new environment .
What produces organisms with similar adaptations but different ancestry?
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.
What is adaptive radiation punctuated equilibrium coevolution?
Coevolution, Convergent Evolution, Adaptive Radiation, Punctuated Equilibrium. STUDY. coevolution. when two species evolve in response to changes in each other over time (in relationship to each other)
What’s an 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. ... Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.
Is convergent evolution an example of adaptive radiation?
The recurrent evolution of convergent forms is a widespread phenomenon in adaptive radiations (e.g., [1-9]). ... In all these cases, convergent phenotypes originated in geographic isolation from each other.
What are the 5 evidence of evolution?
Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos .
What are examples of analogous structures?
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
What are the four types of evidence for evolution?
Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation .
What are some examples of adaptive radiation?
A striking example is the radiation, beginning in the Paleogene Period (beginning 66 million years ago), of basal mammalian stock into forms adapted to running, leaping, climbing, swimming, and flying. Other examples include Australian marsupials, cichlid fish , and Darwin’s finches (also known as Galapagos finches).
What are the 7 patterns of evolution?
Groups of species undergo various kinds of natural selection and, over time, may engage in several patterns of evolution: convergent evolution, divergent evolution, parallel evolution, and coevolution .
How does adaptive radiation occur?
An adaptive radiation occurs when a single or small group of ancestral species rapidly diversifies into a large number of descendant species . ... An ecological opportunity occurs when a small number of individuals of a species are suddenly presented with an abundance of exploitable resources.
What is an example of convergence?
A convergence is when two or more distinct things come together. ... An example of technology convergence is smartphones , which combine the functionality of a telephone, a camera, a music player, and a digital personal assistant (among other things) into one device.
How does convergent evolution occur?
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 the main difference between the two types of evolution?
The main difference between parallel and convergent evolution is that parallel evolution describes the independent evolution of two species, maintaining a same level of similarity whereas convergent evolution describes the origination of analogous traits in distinct species.
Are Darwin’s finches an example of adaptive radiation?
Darwin’s finches are a classic example of adaptive radiation . The ecological diversity of the Galápagos in part explains that radiation, but the fact that other founder species did not radiate suggests that other factors are also important.
