Alloplastic vs. Autoplastic Evolution
Robots and A.I. systems that we create as external tools represent what has been called "alloplastic adaptation": adaptation of ourselves and of our capabilities through changes we induce in environments and objects outside our bodies. Even a simple hammer and nail exemplify alloplastic adaptation, in virtue of expanding our construction capabilities, without having our having to wait a million years for our fists and finger nails to mutate into them, or to otherwise change ourselves.
By contrast, genetic human re-engineering, and by analogy, permanent high-tech human brain or other implants, performance-enhancing pharmaceuticals, robotic prostheses and ingested blood-regulating nanomachines and nanoparticles represent "autoplastic adaptation": evolutionary, often irreversible change — and, if we're lucky or wise, also positive adaptive advances — of, within and in some cases those permanently on our bodies that facilitate and represent self-evolution and self-adaptation adaptation of, by and for the self).
