Tautonymy
Hello, Nivedhan gandhi. I read your feedback at the article Black rat, and would like to answer your question. As the article Tautonym explains, identical genus and species designations are permitted in zoology (animals) but are forbidden in botany (plants). Many tautonymous animal names (including Rattus rattus itself) were assigned by Carl Linnaeus, who devised the system of binomial nomenclature. Deor (talk) 13:05, 14 October 2012 (UTC)
