What is the theory of special creation CORRECT ANSWER - all species are independent -life on earth is young-6000 yrs. old -species are immutable typological thinking CORRECT ANSWER based on idea that species are unchanging types and that variations within species are unimportant/misleading great chain of being CORRECT ANSWER Aristotle believed that there's a ladder of nature that orders based on increased size and complexity (humans are at the top) Lamark's theory of "change throu...
