It sounds like you may be referring to "social Darwinism," a belief that individuals, groups, and societies are subject to the same laws of natural selection as plants and animals.

It wasn't! Social Darwinism is a concept developed by Herbert Spencer and has nothing to do with the biological theory of evolution by natural selection. It is a Landmarkian concept in a fashion as groups compete with groups and acquired group superiority's are passed on. Also, the theory of evolution by natural selection is a individual selection theory, basically, and has nothing to do with group selection of this nature. Darwin was not pleased by this Spencerian corruption of his theory. PS: I, personally, am appalled that this nonsense is still being taught in schools. Tell your teacher ( sociology, perhaps? ) to get a clue!
Social Darwinism is the theory that individuals, groups, and peoples are subject to the same Darwinian laws of natural selection as plants and animals. It was used to justify social and economic inequality, arguing that those who were the fittest would naturally rise to the top while the weak would fall behind.
