Exobiology is the scientific search for life-forms existing elsewhere in this universe, whereas exoevolution involves speculating on the adaptive histories of organisms on other worlds. It is not generally known that, at least once in his life, Charles Darwin envisioned the existence of plants and animals on another world.
