Question

What is the main result of natural selection?

Answer 1

The main result of natural selection is the evolution of populations over time. Natural selection is a process that leads to changes in the genetic makeup of a population, favoring traits that enhance an organism's ability to survive and reproduce in a given environment. As a result, beneficial traits become more common in the population over generations, while less advantageous traits may diminish or disappear. This process can lead to adaptations—characteristics that enhance the fitness of organisms—and can ultimately result in the emergence of new species, contributing to the biodiversity we observe today.
