About the NAS Award in the Evolution of Earth and Life
Established by the NAS Council in June 2017 by combining two awards: the Daniel Giraud Elliot Medal and the Mary Clark Thompson Medal. The award rotates presentation between the Elliot Medal that recognizes meritorious work in zoology or paleontology published no earlier than the last presentation of the medal (2018), and the Thompson Medal that honors important services to geology and paleontology. Each medal is presented with a $20,000 prize.
Daniel Giraud Elliot Medal History
Established through the Daniel Giraud Elliot Fund by gift of Miss Margaret Henderson Elliot. First awarded in 1917 to Frank M. Chapman, the Daniel Giraud Elliot Medal has recognized the most prestigious zoologists and paleontologists over the past 90 years. Two-time Daniel Giraud Elliot Medal recipient, George Simpson proceeded to win the National Medal of Science in Biological Sciences. John Northrop received the Elliot Medal in 1939 before receiving the 1965 Nobel Prize in Chemistry.
Mary Clark Thompson Medal History
The Mary Clark Thompson Medal was established in 1919 by a gift from Mary Clark Thompson to honor important services to geology and paleontology.
Most Recent Recipients

Shuhai Xiao, Virginia Tech, received the 2021 NAS Award in the Evolution of Earth and Life - Mary Clark Thompson Medal.
Xiao is a renowned paleobiologist and geobiologist who studies the interactions between the biosphere and its environments at critical transitions in Earth history, particularly during the Ediacaran-Cambrian transition. Xiao integrates geological, geochemical, and paleontological research on the evolution and radiation of eukaryotes, of algae, and of animals in the Ediacaran and Cambrian periods. Through this approach, Xiao’s contributions at the interface of geology and paleontology have re-envisioned our understanding of the evolutionary transformation from the mainly microbial world of the Proterozoic to the diverse multicellular life of the Ediacaran and Cambrian periods.

Award History
Previous recipients of the NAS Award in the Evolution of Earth and Life continue to achieve outstanding advancements in their fields. Seven recipients have been honored with a National Medal of Science, and one recipient has received a Nobel Prize in Chemistry (Northrop 1946).
Recipients:
Terrie M. Williams (2024, Daniel Giraud Elliot Medal)
For her pioneering research at the interface between physiology, behavior, and ecology. She developed novel technologies for field measurements of the physiology of free-ranging animals, and she has discovered basic principles about the ecological performance of large predatory mammals in both marine (whales, seals) and terrestrial (lions, cougars) habitats.
