    Understand the evolutionary mechanisms and environmental limits of life. Determine the molecular, genetic, and biochemical mechanisms that control and limit evolution, metabolic diversity, and acclimatization of life.

  2. A Geobiological Perspective on the Emergence of Animal Life


    Researchers from NAI’s University of Hawai’i Team and their colleagues have a new paper in Geobiology reviewing recent work on the climatic, geochemical, and ecological events that preceded animal fossils, considering their portent for metazoan evolution. They also consider recent published research on the nature and chronology of the earliest fossil record of metazoans, and on the molecular-based analysis that yielded dates older than the last 35 million years of the Precambrian for the appearance of major animal groups.

  3. NASA Predicts Non-Green Plants on Other Planets


    NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.

    Green, yellow or even red-dominant plants may live on extra-solar planets, according to scientists whose two scientific papers appear in the March issue of the journal, Astrobiology. The scientists studied light absorbed and reflected by organisms on Earth, and determined that if astronomers were to look at the light given off by planets circling...

  4. Carl Woese and New Perspectives on Evolution


    Scientists are proud when they discover a new species or genus of life, but one molecular biologist, Carl Woese, has the unique honor or discovering an entire domain of life, the archaea.
