Doesn't natural in this context mean anything that derives immediately from the primordial order of the world? Like maths, physics, chemistry with biology being in the gray zone?
Because it operates on fairly simple mechanisms that derive from typical natural sciences but there is such a multitude of possibilities to achieve the same goal (like basing life on carbon or silicon that achieve the same goal with an extremely different set of mostly mutually exclusive possibilities) unlike in physics or maths that can be determined by something ultimate.
I would put biology between natural (like maths, physics) and artificial (like literature, language, culture) because it fits truly both and neither.
