EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Birds of the same species were blown from the mainland to a nearby selection acts in favor of the birds with smaller beaks, as birds with large and medium sized breaks have a harder time gathering food. this process is an example of which of the following choices?
A
relative fitness
B
stabilizing selection
C
directional selection
D
disruptive selection
E
sexual selection
Explanation: 

Detailed explanation-1: -Birds of the same species were blown from the mainland to a nearby island in a storm. While living on the island, natural selection acts in favor of the birds with smaller beaks, as birds with large and medium sized beaks have a harder time gathering food.

Detailed explanation-2: -Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

Detailed explanation-3: -Microevolution is visible when the bigger beaks of finches are expressed more over time because it can help their species survive better. 2. It is common for populations to satisfy the Hardy-Weinberg Equilibrium.

Detailed explanation-4: -Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases.

Detailed explanation-5: -Each type of selection contains the same principles, but is slightly different. Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection favors the middle phenotype, causing the decline in variation in a population over time.
