What is the difference between divergent convergent and parallel evolution?

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 the similarities of convergent and divergent?

The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.

What is parallel convergent and divergent?

A convergent beam of light: Light rays comes together (converges) after reflection and refraction at a single point known as the focus. Such a beam of light is called a divergent beam of light. Parallel beam of light: A parallel beam of light is light that is parallel to each other when coming from the source of light.

What is 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.

Which two organisms show convergent evolution?

One of the best-known examples of convergent evolution is the camera eye of cephalopods (such as squid and octopus), vertebrates (including mammals) and cnidaria (such as jellyfish).

What is an example of divergent evolution?

Mammals are an example of divergent evolution because they became very dissimilar over a long period of time, yet still retain similar structures that indicate they are related somewhere on the tree of life.

What is divergent evolution biology?

Divergent evolution is a type of macroevolution that creates more diversity in species in the biosphere. Sometimes, divergent evolution occurs through chance happenings over time. Other cases of divergent evolution become necessary for survival in a changing environment.

What is the definition of divergent selection?

Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation.
