Written by Dina Fine Maron for National Geographic. [Excerpt] “Their goal is to uncover more information about how these animals move, eat, and what their genomes look like. Long hopes to detail how elephants without the benefit of tusks as tools may alter their behavior to get access to nutrients. Rob Pringle, at Princeton University, plans to look at dung…
“The persistence of elephant poaching has prompted researchers to wonder whether elephants really needed their tusks, and whether they might not be better off if the tuskless trait were to spread more widely through the African population. Shane Campbell-Staton, an assistant professor of ecology and evolutionary biology at the University of California, Los Angeles, and his colleagues have begun systematically…
The silky anteater (Cyclopes didactylus) has previously been recognized to be a single species divided into several sub-species. But a new genetic analysis, published in the Zoological Journal of the Linnean Society, suggests that this enigmatic mammal is not one species, but seven separate ones. Lead author Dr. Flávia Miranda, a researcher with the Universidade Federal de Minas Gerais, Brazil, and…
A new study co-led by Indiana University that tracked the eye movement of twins finds that genetics plays a strong role in how people attend to their environment. Conducted in collaboration with researchers from the Karolinska Institute in Sweden, the study offers a new angle on the emergence of differences between individuals and the integration of genetic and environmental factors in social,…
