Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a population of squirrels, short tails prevent predators from catching the short-tailed squirrels while they are on the ground. The longer tails help the squirrels balance better when up in the trees. Medium-length tails do not give a benefit, so there are very few medium tail squirrels. What type of natural selection is shown?
A
stabilizing selection
B
disruptive selection
C
directional selection
Explanation: 

Detailed explanation-1: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

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: -According to Charles Darwin’s theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
