Since for Proximate (or mechanistic), causation it should explain how actions occur in terms of the genetic, neurological, hormonal, and skeletal–muscular mechanisms involved. But fly rules does not belong to any of it.

However, for Ultimate (or evolutionary) causation, it should based on their evolutionary consequences and history.

So I am really confused, the three fly rules belong to which explanation.

Thank you!

    $\begingroup$ Welcome to SE Biology. Please finish reading the Tour, which describes how this site works. Then read the Help on Homework questions which explains that you must show your attempt to answer the question yourself and how to present the question. Just pasting an image of the question (which is inaccessible to those with visual difficulties) without presenting it yourself is not adequate in my opinion, especially given the reference to a video and "rules" which I find difficult to understand. $\endgroup$ – David Jun 2 '20 at 9:56
