A general ballpark how one can predict the way how evolution will work in the future would be by thinking about the requirement of a certain area or environment and which changes would be necessary and relevant for any organism to thrive with its new changes.
This could help people speeden up this process by enabling organisms to develop such traits faster, as well as ourselves.
