  • Fossils aided the progress of this development
    • There are gaps where many early life forms were soft-bodied, so we have not all the starting points.
      • Geological activity may have destroyed much of fossil eveidence.
        • Anti-biotic resistant strains of bacteria evolved rapidly, where mutations occur every time, and survive and reproduce.
