Answer:
a discovery by a human being
Explanation:
The correct answer would be a discovery by human being.
Penicillin existed in nature and was only discovered, albeit accidentally, by Alexander Fleming.
It is different from technological innovation because the latter requires the synthesis of products that are not in existence already or improvement on a product that has been created before.
Discovery is also different from advancement in technology. The latter refers to the process of inventing, innovating, and spreading technological processes in society.
Discoveries are usually natural and are not in any way an invention. However, advancement in technology can aid discoveries.
