Which statement best describes the concept of natural selection?
A
Natural selection is the process by which organisms with favorable traits are more likely to survive and reproduce.
B
Natural selection is the random change in allele frequencies in a population over time.
C
Natural selection is the intentional breeding of organisms to produce desired traits.
D
Natural selection is the process by which organisms acquire traits during their lifetime and pass them on to offspring.
Verified step by step guidance1
Natural selection is a fundamental concept in evolutionary biology, describing how certain traits become more common in a population due to differential survival and reproduction.
The key aspect of natural selection is that it is not random; it favors organisms with traits that enhance their survival and reproductive success in a given environment.
Natural selection differs from genetic drift, which is a random change in allele frequencies, and from artificial selection, which involves intentional breeding for specific traits.
Traits acquired during an organism's lifetime, such as learned behaviors or physical changes due to environmental factors, are not passed on through natural selection, as it acts on heritable genetic traits.
Understanding natural selection involves recognizing its role in shaping the genetic makeup of populations over generations, leading to adaptation and evolution.
