Evolutionary Milestones
Archaebacteria have passed no evolutionary milestones.
Habitat
Archaebacteria can be found in extreme environments. They Iive in extreme temperatures and resources. For example, they can be found in thermal vents at the bottom of the ocean and in ice. Archaebacteria are aerobic, cannot exist without oxygen, and anaerobic, can exist without oxygen.

Anatomical/Structural Features
How do they Acquire nutrients
Autotrophs- they produce their own food.
What do they eat
Archaea obtain energy by extracting it from inorganic compounds. Unlike most autotrophs they don't need the sun to acquire energy, and they don't need or produce oxygen.
What eats them
Since archaebacteria live in very extreme environments where other species cannot live, they don't really interact with other organisms. Therefore they don't have a predator.
Symmetry
lack symmetry
Mobility
Archaebacteria move by using their flagella. A flagella is a long, table-like projection with a whiplike motion that helps a cell move through a watery environment.
Reproduction
They reproduce asexually by binary fission. In this process the cell's chromosomes will replicate and then move to opposite ends of the cell. When this happens the cell elongates. Finally a new piece of plasma membrane and cell wall forms dividing the cell into two identical cells.
Development
Development includes the seven characteristics of life.
Other Information
Archaebacteria can go through conjugation, which is when two cells exchange genetic info by attaching their pili together. This creates more genetic diversity among the population.
