Which author argued in the origin of species that living things have changed over time because of the struggle for limited resources? a. jean-jacques rousseau b. charles wingspanens c. charles darwin d. karl marx

C. Charles Darwin.

Well, Charles Darwin is the author of "the Origin of Species", so he is the correct answer. He did introduce the idea  of natural selection and evolution, which does mean that organisms evolve over time to adapt to the environment. Marx wrote "the communist manifesto", Rousseau was a philosopher who's ideals inspired the French Revolution, and Charles Dickens was an author and social critic, so they aren't the correct response.
