Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.

Answer:
Natural selection.
Explanation:
Imagine in the beginning there was a single species of bird. Naturally, this bird had to expand to the rest of the world, and was distanced as the continents drifted off. But this bird had to cope with various climates and environments. So the bird would gradually mutate over time. The bird in the jungles of central america would develop different colors and a shaped beak, and would better help it survive. This led to being the new normal for birds of this area. It would evolve to cover all the surviving birds in the region, until it is so drastically changed then it is a new species. There are so many different environments, each with its own challenges to overcome, so so many different bird evolve to survive them.
