### I was using the term in the strictly biological sense. I know that
philosophers decry the definition as tautological, trivial,
unfalsifiable and consequently explanatorily infirm (to quote from the
page you linked to).

I don't mind. For biologists this definition works fine. Objections
from guys who maybe never even dissected a frog won't distract us.
