New research on ‘endowment effect’ points to evolutionary roots of cognitive biases
Jun. 2, 2020—New research from may explain why we sometimes overvalue items we’ve acquired—to an irrational degree—irrespective of their market or sentimental value. This phenomenon is called the endowment effect, and researchers have long puzzled over why it occurs, and why the size of the effect can vary so much across items when it does. It’s important...
Vanderbilt lab develops app for analyzing crowd-sourced songbird recordings
Jun. 2, 2020—Amateur birders and citizen scientists will soon have a novel way to contribute to groundbreaking research. With a new app, created and shared by the team at laboratory of Nicole Creanza, Assistant Professor of Biological Sciences and @EvolutionVU member, researchers can better leverage crowdsourced fieldwork and audio recordings from bird enthusiasts to accelerate the progress...
New method reveals how differences in the genetic “instruction booklet” between humans and Neanderthals influenced traits
Oct. 8, 2019—When it comes to our differences from Neanderthals, most of what we know comes from comparing fossils. But fossils can only tell us about bones and not whole living organisms. That’s changing thanks to a new paper from graduate student Laura Colbran in the lab of Tony Capra, Associate Professor of Biological Sciences and @EvolutionVU...
Intense look at La Brea Tar Pits explains why we have coyotes, not saber-toothed cats
Aug. 7, 2019—The La Brea Tar Pits are an one-of-a-kind fossil site in Los Angeles. The site contains fossils of predators that tried to eat horses, bison and camels stuck in the tar over the past 50,000 years and themselves became trapped, offering the best opportunity to understand Ice Age animals facing climate change. In the most...
Dolphin ancestor’s hearing was more like hoofed mammals than today’s sea creatures
Jul. 19, 2019—Evolution@Vanderbilt paleontologists Rachel A. Racicot, visiting scholar, and Simon A.F. Darroch, Assistant Professor of Earth and Environmental Sciences, and their collaborators are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make – part of the rare echolocation ability that allows them to effectively navigate their dark environment. The study...
