His Field Guide to Western Reptiles and Amphibians, first published in 1966, is still considered the definitive reference of its kind, owing to both the quality of the illustrations and the comprehensiveness of the text. A professor of zoology at the University of California, Berkeley, for over 30 years, he was the first curator of herpetology at the Museum of Vertebrate Zoology, a 1949 Guggenheim fellow, and author of over 70 scientific articles. His discovery of the ring species phenomenon in Ensatina salamanders is now a textbook example of speciation, and he performed extensive research on the parietal eye of reptiles. He produced nature films, supported science education in primary grades, and organized conservation efforts that aided in the passing of the 1994 California Desert Protection Act. After retirement he continued to paint, collect field notes, and write books. Stebbins is commemorated in the scientific names of three species: Batrachoseps stebbinsi, the Tehachapi slender salamander; Anniella stebbinsi, a legless lizard; and Ambystoma tigrinum stebbinsi, the endangered Sonora tiger salamander.

The Order of Things: An Archaeology of the Human Sciences by Michel Foucault, proposes that every historical period has underlying epistemic assumptions, ways of thinking, which determined what is truth and what is acceptable discourse about a subject, by delineating the origins of biology, economics, and linguistics. The introduction to the origins of the human sciences begins with detailed, forensic analyses and discussion of the complex networks of sightlines, hidden-ness, and representation that exist in the group painting Las Meninas by Diego Velázquez. Foucault's application of the analyses shows the structural parallels in the similar developments in perception that occurred in researchers’ ways of seeing the subject in the human sciences.
