History and archeology of the transisthmian roads of Panama
Paleontology and Paleobiology
To understand the present and predict the future we need to learn from the past. Ancient tree fossils from a higher-carbon period millions of years ago may help Smithsonian scientists predict how forests will respond to future climates. Similarly, the remains of corals, sponges, snails and sharks just a few thousand or hundred years old can help reconstruct what tropical reef ecosystems were like before humans — and perhaps aid the conservation of these radically altered these ecosystems.
