Evolutionary Studies Initiative

Beckman Scholar Charu Balamurugan, an undergraduate researcher in the Rokas lab at Vanderbilt University, has shed light on the intricate evolutionary patterns governing secondary metabolite biosynthesis in fungi. Balamurugan delved deep into the genomes of Penicillium species, uncovering fascinating insights into the conservation and evolution of biosynthetic gene clusters and associated resistance genes.

Justin Critchlow, a recent Ph.D. student in Ann Tate’s lab, just published a paper with the labmates Arun Prakash, Katherine Zhong, and Tate, uncovering the intricacies of beetle immune dynamics. This paper sheds light on the dynamics of survival, resilience, and the profound complexities inherent in evolutionary adaptations. Read More

Monica Keith, assistant professor of anthropology, recently published insights into the complex factors contributing to maternal hypertension and health disparities. This research sheds light on the alarming rates of hypertensive disorders of pregnancy in the United States, particularly among Black mothers. Read More

Nicole Creanza and Yakov Pichkar explore whether subtle cultural differences within a language mirror genetic structure within a population. The answer: Even small cultural differences like dialect can influence the spread of people and genes. Read More

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 Nicole Creanza. The study found that populations can increase their cultural repertoire by subdividing knowledge into smaller groups, but the total group must be sufficiently large for specialization to be advantageous.

A new study led by members of Ann Tate’s lab found evidence that pleiotropy may slow down evolution of genes involved in immunity. Read More

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. Read More

Sarah Worthan, along with Robert McCarthy and Megan Behringer, led a new effort to understand the effects of the environment on the outcome of experimental evolution studies. Read More

Stephen Ferguson, first-author of a new paper with his postdoctoral advisor, Laurence Zwiebel, along with two undergraduates associated with the lab, Isaac Bakis and Nicholas Edwards, confirmed the existence of a specialized soldier caste within an ant species. Read More

Vanderbilt researcher Amanda Lea, along with a global team of experts, has discovered new pathways of natural selection in humans. Read More

Joan Strassmann, a world leading expert on the evolution of cooperation and fellow of the U.S. National Academy of Sciences, will be giving a talk on experimental evolution of microbes on Friday Feb. 24th. Read More

Local students from Stratford and Overton high schools got to excavate 70 million-year-old oysters, clams and shrimp at the Evolutionary Studies Initiative fossil search. The event aimed to teach students about food webs and to connect students with ESI grad students, postdocs and faculty to talk about college, science and evolution. Read More

By Andy Flick Associate Professor of Psychology and Human Development Laura Novick, and graduate student Joanna (Jingyi) Liu, published a paper highlighting the importance of intentionally and thoughtfully designed figures to explain evolutionary relationships and overcome preconceived misconceptions. The work was inspired, in part, by a common misconception… Read More

Laura Novick and Jingyi Liu published a paper highlighting the importance of intentionally and thoughtfully designed figures to explain evolutionary relationships and overcome preconceived misconceptions. Read More

Julián F. Hillyer, professor of biological sciences, and his research team discovered how mosquito immune and circulatory systems are related. This work may lead to the development of novel strategies that protect beneficial insects or harm detrimental ones. Read More

Amanda Lea, assistant professor of biological sciences, has been named to the 2022–24 cohort of the Canadian Institute for Advanced Research Azrieli Global Scholars in recognition of her outstanding early-career research and interdisciplinary work. Lea’s research interests span evolutionary biology, genomics and human health.  Read More

Vanderbilt and Arizona State University microbiologists explore the effects of feast and famine cycles on E. coli, providing insight into how the bacterial communities that reside in our guts, with our crops, in lakes and streams, and beyond become so complex. Read More

Amanda Lea, assistant professor of biological sciences, has been named a 2022 Searle Scholar, an honor bestowed on 15 exceptional young faculty in the biomedical sciences and chemistry. Lea will receive $300,000 in flexible funding to support her work over the next three years. Read More

A team of Vanderbilt researchers led a project that studies chemical compounds produced by bacteria. Specifically, the group was interested in a suite of chemicals known as natural products. These chemicals are produced by the organism for a specific purpose, but are often valuable because they may be used as antibiotics, anticancer agents, or other therapeutics. Read More

Members of the Evolutionary Studies Initiative took a field trip to Coon Creek Science Center (CCSC) to dig for fossils. Read More
