Change your results

Change search results by adding or removing a year:

  • 2003
  • 2004

  • Change seach results by adding or removing a roadmap objective:

  • 1 Determine whether the atmosphere of the early Earth, hydrothermal or exogenous matter were significant sources of organic matter.
  • 2 Develop and test plausible pathways by which ancient counterparts of membrane systems, proteins and nucleic acid were synthesized from simpler precursors and assembled into protocells.
  • 3 Replicating, catalytic systems capable of evolution, and construct laboratory models of metabolism in primitive living systems.
  • 4 Expand and interpret the genomic database of a select group of key microorganisms in order to reveal the history and dynamics of evolution.
  • 5 Describe the sequences of causes and effects associated with the development of Earth's early biosphere and the global environment.
  • 6 Define how ecophysiological processes structure microbial communities, influence their adaptation and evolution, and affect their detection on other planets.
  • 7 Identify the environmental limits for by examining biological adaptations to extremes in environmental conditions.
