‘Survival of the Fittest’ continues to be a confusing phrase, perhaps because it is often envisioned as individuals competing against individuals, where the fittest species collectively sends the other species to extinction.
In ‘The Origin of Species’, Charles Darwin uses the term ‘Natural Selection’ to describe the key evolutionary process. The phrase ‘Survival of the Fittest’, although typically attributed to Darwin, was introduced by Herbert Spencer and then adopted by Darwin in a later book. Darwin wrote:

The many examples of animals that travel in groups, such as zebra (prey) and jackals (predator), are strongly suggestive of those animals with a tendency to form larger groups having a survival (reproductive) advantage over individuals. Did zebra begin to travel in herds for safety because their predators became pack hunters, able to collectively bring down a larger animal? Did changes in their environment eliminate smaller game, giving pack hunters and advantage over individuals? Species often evolve together and so their evolutionary paths are related, because other species are part of the
