Existence itself is a permanent transformation, a constantly-evolving system. You speak of changes made to the body, but I think grief, for example, shakes up identity much more. My aim is not so much a transformation of my essence, as the wish to respond to an eternal frustration: to finally feel the animal otherness in myself, but also to stop thinking from a purely anthropocentric point of view.
“We are in the Age of Arthropods, in the fossiliferous rocks the oldest have suddenly appeared the species belonging to the great divisions of animals. But we are in the Age of Arthropods, far more numerous than Mammals.” — Georges Aperghis, Sextuor l’origine des espèces, New York debut.
