Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a particular population of island finches, smaller than average individuals suffer from reduced fitness because they cannot consume the larger seeds that appear in abundance in their habitat. Likewise, larger than average individuals of the same species suffer from reduce fitness due to increased predation from raptors on the island. What type of selection would result from this scenario?
A
Directional selection
B
Stabilizing selection
C
Sexual dimorphism
D
Disruptive selection
Explanation: 

Detailed explanation-1: -Likewise, larger than average individuals of the same species suffer from reduce fitness due to increased predation from raptors on the island. What type of selection would result from this scenario? Explanation: Stabilizing selection occurs when the individuals on both phenotypic extremes are selected against.

Detailed explanation-2: -Explanation: With regard to evolution and natural selection, fitness refers only to the ability of an organism to contribute to the next generation of its species. In other words, if an organism has a large number of viable offspring, its fitness is high, regardless of other factors like strength, size, and longevity.

Detailed explanation-3: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-4: -adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.

Detailed explanation-5: -Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time.
