Give birth to new life forms
A research of Artificial Life will definitely throw light on what it means for a complex application to be 'alive'. Moreover, ALife researchers think that, in developing artificial life-forms, given time duration, intelligent nature will emerge, much like it performed in human evolution. Hence, there may be any practical applications of an ALife approach. In particular, evolutionary algorithms (where parameters and programs are evolved to perform a particular operation, rather than to exhibit signs of life) are becoming clearly mainstream in AI.
