Document Summary

The time duration in which the first life was seen on earth (not chemical evolution) Special archea bacteria and anaerobic eubacteria are seen that can harness energy by breaking inorganic matter. Started 543 mya and continues to now. Life from life with a genetic program. Capturing, processing and releasing chemical energy (food) To be able to maintain an internal environment different from the external. To be able to balance the internal environment in a certain range (homeostasis) Creating another life from a living organism. Adapting and changing to the environment by generations. Sensing and interacting with the surrounding world. Formerly heavily relied on morphology for classification (size, shape, mobility) Currently classed in a chemical/genetic manner since many species share same morphs. Nucleoid region of the bacteria contains the genetic material. Generally large, gram positive, spore bearing, and forms colonies in chains. Some of them have a flagella for mobility.
