Exactly and when my mom’s friend gets excited she will also start talking very fast. If she is talking to me I just smile and nod and try to pick up as much as possible.

I think it’s asking for specifics how it would be used to develop the Theory of Adaption like studying the same species in different environments to see what differences have developed because of their environment.
