E.g. We can make a glow-in-the-dark rabbit. Rabbits, by their own nature, are not able to glow in the dark. Human, by their own nature, are able to genetically modify other animals. Humans naturally genetically modify a rabbit. That rabbit's altered nature now has the ability to glow in the dark. It, therefore, naturally glows in the dark.
I think you need to distinguish be essential and accidental properties. To say that something is natural seems equivalent to saying that it has an essential form. It seems to me that the glow-in-the-dark color of the rabbit's fur falls within the category of an accidental property, not an essential one.
