Evolutionary processes and large-scale evolution •Natural selection, genetic drift, mutation, migration sources of MICROEVOLUTION, but can these processes explain taxonomic diversification (MACROEVOLUTION)? • left nagging doubts for early researchers studying evolution vs.

Nagging Doubts by Early Researchers 1) How and why do organisms diverge and diversify? 2) How can we explain patterns of variation across species? 3) Can the evolutionary processes of mutation, selection, drift explain how we got millions of diverse species on earth?

    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.
