What is natural selection: the driving force of evolution
It's one of the most revolutionary theories in science.
Natural selection is a critical mechanism by which organisms evolve, alongside mutation, migration, and genetic drift.
So what is natural selection? You may be familiar with the phrase ‘survival of the fittest, which has been used time and time again, sometimes even by nefarious agents seeking to justify their bigotry and racism with genuine scientific concepts.
Natural selection refers to the process by which organisms that are the most adapted to an environment are more likely to survive and reproduce, while those that are less adapted tend to die out. Thus, the fittest survive to pass their genes and over the course of generations, the adapted offspring can replace entire populations and, given enough time, even form new species.
