Question
MULTIPLE CHOICEWhich of the following best describes natural selection?A the process by which organisms adapt to their environment through mutationsB the mechanism of beneficial traits in a population being passed to offspringC the deliberate selection of desirable traits in domesticated animals by humansD the random change in common traits within a population over time
Solution
The best description for natural selection among the options given is B: the mechanism of beneficial traits in a population being passed to offspring.
Here's why:
Natural selection is a key mechanism of evolution. It's 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. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.
Option A is incorrect because natural selection is not about organisms adapting through mutations. While mutations can lead to new traits, natural selection is about these traits being passed on to the next generation.
Option C is incorrect because it describes artificial selection, not natural selection. Artificial selection is when humans deliberately select for certain traits, as they might do in breeding dogs or crops.
Option D is incorrect because natural selection is not random. It's about the non-random survival of genetically determined traits that help an organism to survive and reproduce.
