EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which pattern of evolution results in one species splitting into many over time?
A
coevolution
B
divergent evolution
C
convergent evolution
D
sexual selection
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Speciation is a result of divergent evolution and occurs when one species diverges into multiple descendant species. Darwin’s finches are an example of this.

Detailed explanation-3: -Divergent evolution occurs when closely related species gradually become very different. This most familiar form of evolution occurs when species compete with each other for resources. Some species evolve without converging on similar traits or diverging to different traits.

Detailed explanation-4: -Divergent evolution is defined as the process that occurs when two groups from the same species evolve distinct traits. The two groups may differentiate further with time, eventually resulting in speciation; the development of new species.

Detailed explanation-5: -Whereas convergent evolution involves unrelated species that develop similar characteristics over time, divergent evolution involves species with a common ancestor that change to become increasingly different over time.
