    Fossil records help us understand the present and predict future ecosystems

    By Miquéla Thornton Due to a multitude of human-driven impacts, the Earth is experiencing a biodiversity crisis. It has been referred to as the Sixth Mass Extinction, and scientists are examining similar events in the planet’s geological past looking for clues in ancient ecosystems to help us solve… Read More

    New research on ‘endowment effect’ points to evolutionary roots of cognitive biases

    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… Read More

    New method reveals how differences in the genetic “instruction booklet” between humans and Neanderthals influenced traits

    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… Read More

    Intense look at La Brea Tar Pits explains why we have coyotes, not saber-toothed cats

    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… Read More

    Frog fungus fights back

    Amphibian populations have been declining around the world for more than 40 years. One culprit is the fungus B. dendrobatidis, which causes the disease chytridiomycosis. Although amphibians have robust immune defenses, the response to this pathogen is often ineffective, suggesting that the fungus somehow counters the immune response.

    Dolphin ancestor’s hearing was more like hoofed mammals than today’s sea creatures

    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… Read More

    Ediacaran dinner party featured plenty to eat, adequate sanitation, computer model shows

    Earth’s first dinner party wasn’t impressive, just a bunch of soft-bodied Ediacaran organisms sunk into sediment on the ocean floor, sharing in scraps of organic matter suspended in the water around them. But work from Evolution@Vanderbilt paleontologist Simon A.F. Darroch, assistant professor of earth and… Read More

    Life in evolution’s fast lane

    Most living things have a suite of genes dedicated to repairing their DNA, limiting the rate at which their genomes change through time. But recent work by graduate student Jacob L. Steenwyk in the lab of Antonis Rokas, Evolution@Vanderbilt director, and their collaborators at the University of… Read More
