  • "Archaebacteria" - microorganisms, more properly referred to as Archaea (which is its own Domain seperate from Bacteria and Eukarya) as they are not bacteria, found in extremee environments; geysers, deep sea black smokers, the difference between them and other life is greater than the differences between plant and animal life

  • The falsely labeled "Archaea" bacteria, tube worms, which have evolved to live at temperatures of up to 110 degrees Fahrenheit, and the hyperthermophilic bacteria, which have evolved to live at water temperatures of up to 239 degrees Fahrenheit will be the last life on Earth because of their ability to live at high temperatures ..

  • The three domains include diverse life forms such as the Eukarya (organisms, including humans, yeast, and plants, whose cells have a DNA-containing nucleus) as well as Bacteria and Archaea (two distinct groups of unicellular microorganisms whose DNA floats around in the cell instead of in a nucleus).
