Article Evaluation for "Substance P"
The article stays focused for the most part. Perhaps the only notable deviation from topic occurs when the discovery of substance K is also mentioned. Additionally, the article is quite detailed while remaining neutral and unbiased. The sources accurately line up with the claims made in the article and seem to be from reputable, peer-reviewed journals. The article may be improved by selecting more recent sources as opposed to primarily using sources from the 1900s and early 2000s.
