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...
