Vanderbilt Postdoctoral Researcher Reveals Genomic Secrets of Ocean Sponges
Dec. 4, 2023—By: Sarah Ward Evolutionary Studies graduate communications assistant Picture a thriving marine environment. Perhaps you envision a community as colorful and lively as “Finding Nemo,” where massive schools of fish are flanked by sharks and sea turtles. What about sponges? While perhaps less popular than their flamboyant counterparts, these organisms are the foundation of life...
Researchers Reveal Insights into Bacterial Genome Evolution
Oct. 15, 2023—By Andy Flick, Evolutionary Studies Scientific Coordinator In a new study led by graduate student Carl Stone and his advisor, assistant professor of biological sciences, Megan Behringer, the team studied the effects of DNA repair pathways on genome-wide methylated DNA adenines (6mA). 6mA is a modification to DNA such that a methyl group is added...
Vanderbilt Researcher Illuminates the Impact of Sunlight on Eye Function
Sep. 22, 2023—By: Andy Flick, Evolutionary Studies scientific coordinator A recent study by assistant professor of biology and ophthalmology Gianni Castiglione illuminates our understanding of eye diseases like macular degeneration. The paper, Convergent evolution of dim light vision in owls and deep-diving whales, was published in “Current Biology.” Rhodopsin (RHO), a light-sensitive protein found in the rod...
Carlos Taboada Joins Vanderbilt University and Evolutionary Studies Initiative
Aug. 28, 2023—By: Andy Flick, Evolutionary Studies scientific coordinator Carlos Taboada is the newest member of the Vanderbilt University Evolutionary Studies Initiative. Taboada’s research focuses on the evolutionary biochemistry of animal coloration. In Taboada’s words, “our lab lies at the interface of biochemistry, evolution, and visual ecology. We investigate the mechanisms that explain remarkable optical traits in...
Evolutionary Studies pilot grant recipients reflect on last year’s research
Jul. 6, 2023—By Kelly Tingle, Evolutionary Studies communications assistant Last year (2022-2023), Evolutionary Studies at Vanderbilt awarded pilot grants to excellent proposals from four members of the ESI community: graduate students Samantha Schaffner (Biological Sciences, Patel Lab), Taiye Winful (Anthropology, Benn Torres Lab), and Katie McCormack (Anthropology, Benn Torres Lab) and Earth and Environmental Sciences Professor Lin...
How do interactions between individuals from different populations contribute to cultural richness?
May. 3, 2023—By: Yotam Ben-Oren (The Hebrew University of Jerusalem), Erella Hovers (The Hebrew University of Jerusalem), and Oren Kolodny (The Hebrew University of Jerusalem), Nicole Creanza Assistant Professor of Biological Sciences (VU) Why are human cultures so diverse? What makes some cultures richer than others? How can very small populations possess very complex cultures? According to...

Mar. 20, 2023—By: Dr. Andy Flick, Evolutionary Studies scientific coordinator Scott V. Edwards, the Alexander Agassiz Professor of Zoology and Curator of Ornithology in the Museum of Comparative Zoology at Harvard University and a leading expert on the evolution of biodiversity, will deliver this year’s J. T. Scopes Lecture on Wednesday, March 29th. The title of his...
Vanderbilt researcher finds evidence for ant caste systems driven by chemo-sensing responses
Mar. 13, 2023—By Andy Flick, Evolutionary Studies scientific coordinator Stephen Ferguson, first-author of a new paper with his postdoctoral advisor, Laurence Zwiebel, Cornelius Vanderbilt Chair in Biological Sciences, and two undergraduates associated with the lab, Isaac Bakis (alumnus) and Nicholas Edwards, confirmed the existence of a specialized soldier caste within an ant species in a paper titled,...
Researchers hope insights into low-light vision of Antarctic icefish can promote better understanding of human health
Feb. 27, 2023—By Tatum Lyles Flick, Evolutionary Studies communications volunteer consultant Though many researchers have considered how fish survive in extreme cold, using everything from antifreeze glycoproteins that protect cells to not producing hemoglobin, few have taken a molecular approach to evaluate how they are able to see in such conditions. In “Adaptation of Antarctic Icefish Vision...
Vanderbilt Researcher Identifies Modes of Natural Selection in Understudied Human Populations
Feb. 16, 2023—By Andy Flick, Evolutionary Studies scientific coordinator (Spanish/español) Amanda Lea, assistant professor of biology, along with a global team of experts, have discovered new pathways of natural selection in humans. The group, led by Tsimane Health and Life History Project co-Director Michael Gurven of the University of California, Santa Barbara, studied two populations of Bolivians...
