Answer:
Natural selection is a theory originally popularized by Charles Darwin. According to this theory, animals in the natural environment change over time as beneficial traits are preserved, and traits which do not advance the species are slowly weeded out. Natural selection, a concept first theorized by Charles Darwin, is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this is survival of the fittest or the organisms that are better suited to the environment in other ways.
