Discussion Board 1: Directional/Stabilizing/Disruptive Selection

Original Post:

1. Searching the internet, find and describe (include a link) an example of directional/stabilizing/disruptive selection. This must not be an example discussed in the book.
2. Provide enough detail as to the specific evidence that the researchers found to base their conclusion. In particular, have the researchers identified the genetic basis for the trait under selection?
