A User's Guide to Metaphors In Ecology and Evolution

Biologists energetically debate terminology in ecology and evolution, but rarely discuss general strategies for resolving these debates. We suggest focusing on metaphors, arguing that, rather than looking down on metaphors, should embrace these terms as the powerful tools they are. Like any powerful tool, metaphors need to be used mindful of their limitations. We give for recognizing metaphors and summarize their major limitations which an hiding of important biological detail, ongoing vagueness rather than increasing precision, and seeming real rather than figurative. By keeping these limitation in mind, metaphors like adaptive radiation, adaptive landscape, biological invasion, and the ecological niche can be used to their full potential, powering scientific insight without driving research off the rails.
