EVOLUTION OF A POPULATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two species that are closely related become increasingly different through
A
divergent evolution
B
disruptive selection
C
convergent isolation
D
competitive relationships
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: -Two species that are very closely related and have undergone divergent evolution are the kit fox (Vulpes macrotis) and the Arctic fox (Vulpes lagopus).

Detailed explanation-3: -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.

Detailed explanation-4: -Another good example of divergent evolution is the origin of the domestic dog and the modern wolf. Dogs and wolves both diverged from a common ancestor.

Detailed explanation-5: -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.
