Final answer:
Natural selection is a fundamental concept in biology that explains how certain traits become more or less common in a population over generations. It involves genetic variation, environmental conditions, and differential reproductive success. Natural selection acts on various aspects of an organism and contributes to the diversification and adaptation of species to their environments.
Step-by-step explanation:
Natural Selection in Biology
Natural selection is a fundamental concept in biology that is responsible for the process of evolution. It is defined as the mechanism through which certain traits become more or less common in a population over generations, based on their impact on survival and reproduction. This process occurs due to the interaction between genetic variation, environmental conditions, and differential reproductive success.
For example, let's consider a population of rabbits. Some rabbits may have genes that make them faster, allowing them to escape predators more easily. These faster rabbits are more likely to survive and pass on their genes to the next generation. Over time, the population will have a higher proportion of individuals with the faster gene, as slower individuals are selectively removed from the gene pool.
Natural selection acts on various aspects of an organism, including physical traits, behaviors, and even physiological processes. It is an ongoing and gradual process that contributes to the diversification and adaptation of species to their environments.
