School of Arts & Sciences biologist Mia Levine and Cara Brand, a postdoc, shed light on an example of coevolution in fruit flies that has implications for human health.
New findings from School of Arts & Sciences biologists show that evolution—normally considered to be a gradual process—can occur in a matter of weeks in fruit flies in response to natural environmental change.
Recent studies led by School of Arts & Sciences’ researchers show that changing social strategies between settings—for example, cooperating at home but not at work—can in fact lead to more cooperative behavior in a society.
Coral sperm require a specific pH to move, according to research from the School of Arts & Sciences, which identifies a signaling pathway that is shared by organisms including humans. The results inform how corals may fare with climate change.
Using 27 years of detailed data on hyena social interactions, a team led by Penn biologists nailed down a pattern of social network inheritance and its implications for social structure, rank, and survival.
Moving from water to land and back again corresponded with distinct changes in animals’ spinal morphology, according to a new study led by paleontologist Aja Carter.
With a frilled head and beaked face, Menefeeceratops sealeyi lived 82 million years ago, predating its relative, Triceratops. Researchers including Peter Dodson, of the School of Veterinary Medicine, and Steven Jasinski, who recently earned his doctorate from the School of Arts & Sciences, describe the find.
An international research team, including Hermann Pfefferkorn of the School of Arts & Sciences, has solved the mystery of where 300-million-year-old specimens fit into the plant family tree.
Junior Ashna Sethi found an opportunity to delve into one of her passions this summer with paleobiologist Lauren Sallan’s lab in the School of Arts & Sciences.
Ancient DNA from 46,000-year-old bone fragments and a tooth reveals this group likely overlapped with Neanderthals for thousands of years.
