What Is Identity?

New Idea blown Up I have just come up with this idea right now, Im sitting here thinking to myslef what has My Martial Arts have to do with Evolution n I been thinking long and hard n theres nothing so instead of me going back to the drawing board n thinking what shall i do that has to do with DNA I could stick with Martial Arts but base it on identity I mean I could include, How do you know its that fighter, By looking at the fighting technique how can you be sure its them, is it appearence, facial hair, fighting stance etc
The Posters I already done for evoloution will still be used
