Vanderbilt Researchers find Evidence for Evolutionary Constraints on Immunity
Mar. 18, 2023—By Dr. Andy Flick, Evolutionary Studies scientific coordinator A new study led by members of Ann Tate’s (Assistant Professor of Biological Sciences) lab found evidence that pleiotropy may slow down evolution of genes involved in immunity. Alissa Williams, postdoctoral researcher, and Thi Ngo, lab alumna, equally contributed to the new paper studying the evolution of...
Vanderbilt Team finds Evolutionary Support for Induced Defenses
Mar. 16, 2023—By Andy Flick, Evolutionary Studies scientific coordinator Graduate student Reese Martin and his doctoral advisor, Ann Tate, assistant professor of biological sciences, used theoretical modeling to identify a potential relationship between genetic pleiotropy and the evolution of immune responses. The pair authored a paper titled, “Pleiotropy promotes the evolution of inducible immune responses in a...
New outreach partnership with Dismas House
Mar. 16, 2023—By Dr. Andy Flick Evolutionary Studies scientific coordinator This spring, a new partnership formed between Evolutionary Studies at Vanderbilt and Dismas House, a residential reentry program for men leaving Tennessee state prisons and jails. Dr. Kyle David, a postdoctoral researcher in the Rokas lab, founded this partnership with coordination from Natalie McMillan, program coordinator for...
Vanderbilt Biologist investigates specialization and its impact on cultural evolution
Mar. 14, 2023—By Kelly Tingle, Evolutionary Studies communications assistant The cultural evolution of a population depends not only on size but also on the degree of specialization within a population, according to a new study published last month by a team of scientists including Biological Sciences Assistant Professor Nicole Creanza. The study found that populations can increase...
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-led Group Discovers Divergent Function in Convergent Evolution of Form
Feb. 22, 2023—By: Andy Flick, Evolutionary Studies scientific coordinator The classic idiom form fits function does not always mean that everything of the same form has the same function. That’s what a group of paleontologists have discovered with the help of fluid physics and preserved fossils. Simon Darroch, assistant professor of Earth and Environmental Sciences, led a...
Vanderbilt Anthropologist Discovers Lasting Effects from Disasters in Bangladesh
Jan. 26, 2023—By: Andy Flick, Evolutionary Studies scientific coordinator Monica Keith, Assistant Professor of Anthropology, recently co-authored a paper addressing severe climate events in Bangladesh and their lasting effects on human health outcomes. Working with Shodagor fishing families in Matlab, the team found that body mass decreased following the flood of 2017 and did not recover by...
Vanderbilt undergraduate compares nuclear and mitochondrial genomic evolution of the fungi Aspergillus section Flavi
Jan. 23, 2023—By Kelly Tingle, Evolutionary Studies communications assistant Former Vanderbilt University undergraduate student Miya Hugaboom provides insight into fungal mitochondrial genomic evolution in a paper she published recently as lead author, along with Biological Sciences graduate student Annie Hatmaker and Professor Antonis Rokas. The study focused on the mitochondrial genomes of 20 different Aspergillus species, a...
