Survival of the fittest is key from "summary" of The Origin of Species (Deluxe Library Binding) (Annotated) by Charles Darwin
In the natural world, competition is a constant force that shapes the evolution of species. The individuals within a population vary in their traits, and those that are better suited to their environment are more likely to survive and reproduce. Over time, this process leads to the accumulation of beneficial traits in a population, making it better adapted to its surroundings. This concept, known as natural selection, is at the heart of Darwin's theory of evolution. The phrase "survival of the fittest" captures the essence of natural selection. It is not the strongest or the most intelligent that survive, but those that are best adapted to their environment. In other words, fitness is not just about physical strength, but about how well an organism is suited to its ecological niche. This can include factors such as camouflage, speed, or the ability to find food or avoid predators. Natural selection acts on the variations that exist within a population. These variations can be the result of genetic mutations, which int...
