Biology can be designated as a science logically distinct from physics and chemistry because its heuristic field is constituted by questions directed
toward whole organisms (plants and animals), cells and their «achievements» rather than toward atoms and molecules as such.
While it is evident to science that there is a functional «teleonomy» or machine - like purposiveness in individual
organisms (for example, the fish's eye is constructed so as to enable it to see under water, the heart
toward pumping blood, the human brain
toward problem - solving, etc.), still there is no hard evidence that life itself, terrestrial evolution or the universe as a
whole has any overarching meaning.
