Answer;
B. Speciation
Explanation;
-Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
-The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.
-An example of speciation is the Galápagos finch. Different species of these birds live on different islands in the Galápagos archipelago, located in the Pacific Ocean off South America. The finches are isolated from one another by the ocean.
