In our lab meeting we were chatting about divergent selection. I was confused at some point because I wasn't sure what was the meaning of this work in comparison to diversifying/disruptive and other types of selection.

Diversifying selection was coined by J. T. Gulick and I haven't found an interesting answer to compare with our contemporary definition of these terms.

The way I understand this is that, divergent selection is broader and include directional selection as well as disruptive selection. Is that correct?
