Steven M. Stanley

Stanley received his Ph.D. from Yale University in 1968. For most of his career he taught geology at Johns Hopkins University (1969-2005). In 1977 Stanley was awarded the Paleontological Society's Charles Schuchert Award which is presented "to a person under 40 whose work reflects excellence and promise in the science of paleontology."Paleontological Society (2009). [https://web.archive.org/web/20021021083806/http://www.paleosoc.org/awards.html "Paleontological Society: Awardees."] Retrieved on 2009-6-22. In 2007 he was awarded the Society's Paleontological Society Medal, which is "awarded to a person whose eminence is based on advancement of knowledge in paleontology." In 2006 Stanley was awarded the Mary Clark Thompson Medal by the National Academy of SciencesNAS (2009).

In 1972 Stanley developed the Predation Hypothesis to explain the evolution of novelties in the Cambrian explosion. Stanley proposed that predation stimulated prey animals to evolve defenses such as shells, rapid swimming, and burrowing. These strategies also opened new avenues of evolution through functional shifts. Hard shells allowed for filter feeding, and deep burrowing allowed animals to gain new access to food resources.Ward, P. D. (2004). Rare Earth. New York: Springer.

Stanley acted as a “personal editor” on several PNAS papers about the controversial Younger Dryas impact hypothesis, starting with the original 2007 paper and continuing even after revelations of misconduct by a key contributor.{{Cite web |last=Dalton |first=Rex |name-list-style=vanc |date=May 14, 2011 |title=Comet Theory Comes Crashing to Earth |url=https://psmag.com/environment/comet-claim-comes-crashing-to-earth-31180 |url-status=live |archive-url=https://web.archive.org/web/20210211004633/https://psmag.com/environment/comet-claim-comes-crashing-to-earth-31180 |archive-date=11 February 2021 |access-date=24 July 2019 |website=Pacific Standard}} He admitted to a Nature reporter that “It has been very controversial… It’s my view that I should help to get this stuff published.”{{cite journal |last1=Jones |first1=N |title=Evidence found for planet-cooling asteroid |journal=Nature |date=2 September 2013 |doi=10.1038/nature.2013.13661 |s2cid=131715496 |url=https://www.nature.com/articles/nature.2013.13661}} The hypothesis was comprehensively refuted in 2023.{{Cite journal |last1=Holliday |first1=Vance T. |last2=Daulton |first2=Tyrone L. |last3=Bartlein |first3=Patrick J. |last4=Boslough |first4=Mark B. |last5=Breslawski |first5=Ryan P. |last6=Fisher |first6=Abigail E. |last7=Jorgeson |first7=Ian A. |last8=Scott |first8=Andrew C. |last9=Koeberl |first9=Christian |last10=Marlon |first10=Jennifer |last11=Severinghaus |first11=Jeffrey |last12=Petaev |first12=Michail I. |last13=Claeys |first13=Philippe |date=2023-07-26 |title=Comprehensive refutation of the Younger Dryas Impact Hypothesis (YDIH) |journal=Earth-Science Reviews |volume=247 |language=en |pages=104502 |doi=10.1016/j.earscirev.2023.104502|doi-access=free |bibcode=2023ESRv..24704502H }}
