How does natural selection affect the characteristics of an organism?

Answer 1

“Adaptations” to better survival characteristics are the outcomes of natural selection.

According to this theory, "nature" "selects" the best traits for better organisms by promoting or eliminating random variations in organism characteristics from the gene pool based on their capacity to increase or decrease the organism's survivability.

Natural selection affects the characteristics of an organism by favoring traits that increase an organism's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, while less favorable traits may become less prevalent or disappear altogether.
