What is the difference between coevolution convergent evolution and divergent evolution?
Environment. Convergent Evolution: Both species live within the same environment. Divergent Evolution: The two species live in different environments than their ancestor.
What is divergent coevolution?
Definition. Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period.
What is divergent evolution example?
Galapagos finches are an example of divergent evolution. Through time, the species evolved morphologically different traits. A prototype example of divergent evolution is Galapagos finches. Charles Darwin’s Beagle voyage led him to conclude that the finches diverged from their descendant species.

What’s an example of coevolution?
Summary. Coevolution occurs when species evolve together. Coevolution often happens in species that have symbiotic relationships. Examples include flowering plants and their pollinators.
What are 2 examples of convergent evolution?
Examples of convergent evolution
Both humans and octopuses (opens in new tab) have camera-like eyes with an iris, a lens and a retina — all essential parts of an imaging device. And both bats (opens in new tab) and birds have wings. As similar as these traits may appear, a closer look reveals their independent origins.
What is the best example of divergent evolution?
One of the most famous examples of divergent evolution is the case of Darwin’s Finches. During Darwin’s travels to the Galápagos Islands he discovered several different species of finch that shared a common ancestor. They lived on varying diets and had beaks that differed in shape and size reflecting their diet.
What is a good example of coevolution?
Herbivores and plants
Similar to the predator-prey relationship, another common example of coevolution is the relationship between herbivore species and the plants that they consume. One example is that of the lodgepole pine seeds, which both red squirrels and crossbills eat in various regions of the Rocky Mountains.
What are two types of coevolution?
Types of Coevolution
Pairwise coevolution (or ‘specific’ coevolution) describes tight coevolutionary relationships between two species. Diffuse coevolution (or ‘guild’ coevolution) refers to reciprocal evolutionary responses between suites of species.
What are 3 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.
Why is the dog divergent evolution?
Dogs and wolves both diverged from a common ancestor. The similarity of the mitochondrial DNA sequences from 162 wolves from various parts of the world and 140 dogs of 60 different breeds, revealed by genomic research, further supported the theory that dogs and wolves have diverged from shared ancestry.
What are 3 examples of coevolution?
Coevolution functions by reciprocal selective pressures on two or more species, analogous to an arms race in an attempt to outcompete each other. Classic examples include predator-prey, host-parasite, and other competitive relationships between species.
What two animals show divergent evolution?
In divergent evolution, two or more distinct species share a common ancestor from which they diverged. A common example is a modern elephant and woolly mammoth. They share a common ancestor and yet evolved into two different species. Another example is the dog, the wolf, and the fox.
