Survival of the fittest is a concept in evolutionary biology that refers to the idea that the organisms that are best adapted to their environment are the ones that are most likely to survive and pass on their genes to future generations. This phrase was coined by the British philosopher Herbert Spencer and later adopted by Charles Darwin to describe his theory of natural selection. Essentially, it means that the individuals with the most advantageous traits will be more successful in reproducing and passing on those traits to their offspring, leading to the gradual evolution of species over time.
