<span>Natural selection is when
species learn to adapt to their environment. They could (1) differential
reproduction, that is, not all organisms are able to reproduce to their fullest
capacity because nature cannot simply sustain it and (2) acquire genes, that is
heredity. Certain characteristics of organisms tend to survive if it continues
to strive. If it survives, this trait is passed down to the next generations
forgetting the other traits but only the one who could survive the environment.

‘organisms inherit advantageous traits, and tend to reproduce more successfully
than other organisms’</span></span>
