What’s the question, I’m confused. Srry couldn’t answer
Social Darwinism explained the operation of society as "survival of the fittest."
People often associate the term "survival of the fittest" with Charles Darwin, but actually it was terminology that came from Herbert Spencer, the founder of what is known as Social Darwinism. (Spencer wouldn't have called it that - he and Darwin were rivals.) Darwin used the term "natural selection" in his descriptions of biological evolution. Spencer was unafraid to apply the same concepts to competition within the human species, contending that the stronger, fitter social or cultural groups will survive better than others and dominate over weaker groups.
The answer is Paranthropus boisei or P. Boisei. This specie was the earliest hominin and is also described as the largest of the Paranthropus family. This species of Paranthropus lived in Eastern Africa from 2.4 until 1.4 million years ago. Archaeologists found hominid bones along with early stone age technology, which was uncovered to be bones of Paranthropus Boisei.
