Wikipedia's peer review process exposes articles to closer scrutiny from a broader group of editors, and is intended for high-quality articles that have already undergone extensive work, often as a way of preparing a featured article candidate. It is not academic peer review by a group of experts in a particular subject, and articles that undergo this process should not be assumed to have greater authority than any other.
After you have created the peer review notice on the talk page, the notice will present some options for creating the peer review page. Select Natural sciences & mathematics.
