Word Association Famous People Carolus Linnaeus Classification/ taxonomy (categorizing similar organisms into increasingly general groups nested categories) George Cuvier Paleontologist; opposed idea of evolutionary change, used catastrophism to explain differences in fossils and current-day organisms James Hutton/ Charles Lyell Proposed gradualism (profound change can take place through cumulative effects of slow but continuous processes) Jean Baptiste de Lamarck Believed species evolve through inheritance of acquired characteristics ; organisms acquire desirable traits and pass those on so that they have a tendency towards more complexity Robert Malthus On Population introduced idea that population growth will always surpass resource growth because population increases exponentially whereas resources increase only arithmetically/linearly ; eventually, there will not be enough resources to support everyone Alfred Russell Wallace Almost published

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
