Lecture 16 L567 L567.  For next time read Zeh&Zeh on website. Sexual Selection II Darwin laid out two kinds of sexual selection (i.e., variation  among individuals in mating success).   1.  Intrasexual selection due to male-male combat  (We won’t  cover this) And 2. Intersexual selection due to female choice  That is not controversial, and is presented in all Evolution  texts. But, does that mean that 1.  Plants cannot have sexual selection? 2.  Hermaphrodites cannot have sexual selection?

    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.
