91�Թ�� Paleontology Graduate Student Brynn Wooten Brings Hell Pigs to the Forefront

Nov. 18, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Archaeotherium, better known by the irresistibly dramatic nickname “Hell Pigs,” belong to an extinct group of mammals from the Eocene and Oligocene. The animals were neither hellish nor pigs, but their odd mix of features has made them a favorite for researchers. Graduate student Brynn Wooten of the...

Giant Ground Sloth Extinction Led to Loss of Ecological Services

Oct. 22, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Giant ground sloths were more than just Ice Age oddities. They were ecosystem engineers whose disappearance reshaped the landscapes they once roamed. A new study from 91�Թ��’s DREAM Lab reveals just how diverse these megaherbivores’ diets were, highlighting the ecological roles that vanished when they went extinct....

City Lights Are Rewriting the Calendar: 91�Թ�� Researchers Show Artificial Light Extends Urban Growing Seasons

Sep. 23, 2025—By Andy Flick, Evolutionary Studies scientific coordinator City lights are rewriting the calendar. A new global study from 91�Թ�� researchers Lin Meng and Huidong Li shows that artificial light at night is more powerful than temperature in extending urban growing seasons — keeping trees greener longer, with consequences for carbon cycling, frost risk, and even...

Partnership with Turkana Community Helps Scientists Discover Genes Involved in Adaptation to Desert Living

Sep. 18, 2025—Originally posted by UC-Berkeley team, edits by Andy Flick Evolutionary Studies scientific coordinator Scientists Discover Key Genetic Adaptations in Partnership with Turkana Pastoralists of Northern Kenya Groundbreaking study reveals how thousands of years of natural selection shaped remarkable adaptations to an extreme environment. Through a collaboration between US and Kenyan researchers and Turkana communities of...

Annie Hatmaker Explores the Global Diversity of a Pathogenic Fungus

Aug. 18, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Annie Hatmaker, Ph.D., has spent the better part of a decade studying fungi and their secondary metabolites – small molecules they use to communicate, defend, and thrive. Her new publication, “Population structure in a fungal human pathogen is potentially linked to pathogenicity,” closes her dissertation work and opens...

A young woman presents a bright pink scientific poster titled "Genomic comparison of Aspergillus..." to a small group of adults in a hallway with gray brick walls and fluorescent lighting. She gestures animatedly while explaining her work. The group listens attentively, their backs partially turned to the camera.

91�Թ�� Trainees Bring Evolution Education to Classrooms Across Tennessee

Jun. 6, 2025—By: Andy Flick, Evolutionary Studies scientific coordinator From rural high schools to elementary classrooms, trainees of the Evolutionary Studies Initiative (ESI) are bringing evolutionary science directly to the next generation. On May 9, a team of graduate students and postdoctoral researchers visited McGavock Elementary School in Nashville to lead a series of hands-on science activities...

91�Թ��’s Evolutionary Studies Initiative Honored with 2025 Friend of Darwin Award

Jun. 4, 2025—By Andy Flick, Evolutionary Studies scientific coordinator The National Center for Science Education (NCSE) has named 91�Թ��’s Evolutionary Studies Initiative (ESI) as one of its 2025 recipients of the prestigious Friend of Darwin award. This national honor recognizes ESI’s outstanding contributions to advancing public understanding of evolution through interdisciplinary research, education, and outreach. Directed...

Pilot Grants: Opening Doors to Fellowships and Beyond

May. 12, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Since its launch, the pilot grant program has supported graduate students and postdoctoral researchers across a wide range of disciplines—including biological sciences, anthropology, Earth and environmental sciences, and biomedical research. Trainees have used this support to jumpstart fieldwork, generate pilot data, and explore new research directions. Several have...

A man with short dark hair, a beard, and glasses sits at a lab workstation. He wears a black hoodie and looks toward the camera with a slight smile. Behind him are two computer screens—one showing a terminal with lines of code and the other displaying a flowchart with scientific diagrams. Shelves above the desk hold plastic lab containers labeled “200 uL Filter” and “1000 uL Filter.”

A Conservative Defense: Downstream NFLs Resist Evolutionary Blitzes

May. 9, 2025—By Andy Flick, Evolutionary Studies scientific coordinator In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing down activity when things get too intense. A new study from 91�Թ�� reveals that these...

Trainee Travel Grants Share 91�Թ�� Research Worldwide

May. 1, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Since the program began in Fall of 2021, 70 trainee travel grants have been awarded across 13 labs in the departments of Biological Sciences, Earth and Environmental Sciences, and Anthropology. These awards have primarily gone to graduate students (49), though postdoctoral researchers (14) and undergraduates have also benefited...
