In the 1870's, the support for evolution came under attack from several directions. Alfred  Russell Wallace, the co-discoverer of evolution, had started to argue that humanity was  exempt from evolution and that there was mystical guiding force that gave evolution  direction. This idea was a direct attack on what had made Darwin's theory so  revolutionary: the idea that evolution was an orderly process that resulted from random  variation and the survival of the fittest. Another attack came from physicists such as  Lord Kelvin, who argued on the basis of measurements of the earth's temperature that  the earth had existed for only twenty-five or thirty million years. An evolutionist required  more time–on the order of hundreds of millions of years–for all of life to have evolved.

    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.
