Here's a breakdown:
* Evolution is the gradual change in the genetic makeup of a population over many generations.
* Natural Selection is a key driver of evolution. It means that individuals with traits better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring.
* Over many generations, these small changes in traits can accumulate and lead to significant differences between populations, eventually resulting in the formation of new species.
So, organisms don't change into something entirely different like a different animal, they change into new, distinct species.
