Proximate questions: in animal behavior, an inquiry that focuses on the  environmental stimuli, if any, that trigger a particular behavioral act, as well as  the genetic, physiological and anatomical mechanisms underling it; “how”  questions Ultimate questions: in animal behavior, an inquiry that focuses on the  evolutionary significance of a behavioral act; “why” questions Male stickleback fish o Proximate cause: the red belly of the intruding male acts as a sign  stimulus that releases aggression in a male stickleback o Ultimate cause: by chasing away other male stickleback, a male  decreases the chance that eggs laid in his nesting territory will be  fertilized by another fish 3. Define fixed action patterns and give an example.

    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.
