The goal of the project, now in its pilot year, is to collect data on the direct and indirect energy inputs and outputs. Martin and her team will analyze this data to determine the energy efficiency and environmental impact of food production on urban and rural farms that practice sustainable methods.

While all life originally arose in the seas, about 370 million years ago one group of fish evolved new anatomical features that enabled them to crawl out of the ocean and take up residence on dry land. This invasion of land by fish was one of the major events in the history of life on earth. Evolutionary biologist Michael Coates will discuss new fossil discoveries that are changing the way we view this moment in natural history.

    If you experience any technical difficulties with this video or would like to make an accessibility-related request, please send a message to digicomm@uchicago.edu. One of the most exquisite discoveries from Gobero is a triple burial which preserved an adult woman interred with two young children. The bodies were buried with their arms around each other and were holding hands. Paul Sereno's vision was to create something unique that would enable people to 1) view the burial from both sides and 2) preserve all of the scientific information in place: from the tiniest bones to the original position of the artifacts. He met with his staff at the University of Chicago Fossil Lab to make a plan. Paleoartist Tyler Keillor brought a "paleo-trifecta" of art, science and innovation to bear in order to help reconstruct this ancient scene.-- Written by Project Exploration
