Why the phrase survived of the fittest does not accurately reflect Darwin and concept of evolutionary fittness?

The phrase "survival of the fittest" misrepresents Darwin's concept of evolutionary fitness by implying that only the strongest individuals survive. In reality, "fitness" in evolutionary terms refers to an organism's ability to adapt and reproduce in its specific environment, which can involve traits beyond mere strength, such as cooperation, intelligence, or reproductive strategies. This phrase oversimplifies the complex nature of natural selection and can lead to misconceptions about evolution as a purely competitive process.
