Parallel evolution: two (or more) species or genera that evolve in similar ways over time.
Divergent evolution: two or more closely related species or genera that evolve to become quite different from one another.
Convergent evolution: two or more unrelated and dissimilar species or genera that evolve to become similar to one another, for example penguins (birds that used to fly), dolphins (mammals that used to walk on land) and fish (animals that were always swimming)

Why do animals exhibit similarities in appearance and characteristics?
Animals exhibit similarities in appearance and characteristics due to shared evolutionary history and adaptation to similar environments. This is known as convergent evolution, where unrelated species develop similar traits to survive in their surroundings.
Is the north American plate divergent transform or convergent?
A plate is not classified as convergent, divergent, or transform, a plate boundary i.e. a boundary between plates is. All three types of plate boundary can be found along the edges of the North American plate.
What venation is canna?
The foliage of canna plants typically exhibit a parallel venation pattern, where the veins run parallel to each other from the base to the tip of the leaf.
Which pair of organisms show convergent evolution?
One example of this type of evolution, where similar useful traits emerge in unrelated species, would be long canine teeth in saber-toothed cats as well as marsupial lions. The organisms are not genetically related, but developed this trait independently of each other.
Why do penguins and grebes have similarities although they are not related?
Penguins and grebes exhibit similarities due to a phenomenon known as convergent evolution, where unrelated species develop similar traits as adaptations to comparable environments or lifestyles. Both birds are aquatic and have evolved streamlined bodies and specialized limbs for swimming, allowing them to thrive in water. These adaptations have arisen independently as a response to the demands of their respective habitats, highlighting the influence of environmental pressures on evolution.
What platy materials have a parallel alignment?
Platy materials with parallel alignment include clay minerals, such as montmorillonite and illite, which exhibit a sheet-like structure. Additionally, mica minerals like muscovite and biotite also display a parallel alignment due to their layered configuration. In sedimentary rocks, siltstone and shale can exhibit this characteristic as well, where particles are oriented in a parallel fashion, indicating depositional processes. This parallel alignment often influences the physical properties of the materials, such as their strength and permeability.
What phenominon Longitudinal waves do not exhibit?
Longitudinal waves do not exhibit polarization, which is a characteristic of transverse waves. Polarization refers to the orientation of the oscillations of the wave with respect to its direction of propagation. Since longitudinal waves have their oscillations parallel to the direction of propagation, they cannot exhibit polarization.
Does bay leaf has parallel venation?
Yes, bay leaves (Laurus nobilis) exhibit parallel venation. This means that the leaf's veins run parallel to each other from the base to the tip of the leaf. Parallel venation is characteristic of certain plant families, including monocots, but bay leaves belong to the Lauraceae family, which can exhibit various venation patterns. However, their leaves often display a slightly curved or arching appearance, which may create a visual effect similar to parallel venation.
Why are convergent volcanoes more explosive than divergent volcanoes?
Convergent Volcanoes are of a different composition, they are more viscous so rise much more slowly and they have a much greater amount of CO2, SO2 and most importantly H20 which causes an immense buildup of steam pressure! Why does aP ressure Cooker become like a dangerous bomb if left unattended while an open pot will just boil off? The same is true here! -Bad Moon Rising's answer from Yahoo! ANSWERS.
Is To succeed is to be happy in life a parallel structure?
No, "To succeed is to be happy in life" does not exhibit parallel structure. Parallel structure involves using the same grammatical form for elements within a series or list. In this phrase, "to succeed" and "to be happy" are in parallel form, but the addition of "in life" disrupts the symmetry, making it a mixed structure.
When two groups of organisms independently evolve similar adaptations its called convergent evolution. Sharks and whales both have streamlined bodies and tail flukes. How do we know that these simila?
Sharks and whales exhibit similar adaptations, such as streamlined bodies and tail flukes, due to convergent evolution, which occurs when unrelated species evolve similar traits in response to similar environmental pressures. Despite their different evolutionary lineages—sharks are fish, while whales are mammals—these adaptations enhance their efficiency in aquatic environments. The similarities in their body shapes demonstrate how natural selection can lead to analogous structures that serve similar functions, highlighting the influence of ecological niches on evolutionary processes.
