Detailed explanation-1: -Evolution is the change in inherited characteristics or traits in a population of organisms over many generations. The mechanism that best explains evolution is a phenomenon known as natural selection.
Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’
Detailed explanation-3: -Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Detailed explanation-4: -Natural selection can cause microevolution, or a change in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations. Fitness is a measure of relative reproductive success.
Detailed explanation-5: -Sometimes summed up by the phrase “survival of the fittest, ‘’ natural selection is based on the following principles: In nature, organisms produce more offspring than are able to survive and reproduce.
