early atmosphere contained toxic gases like ammonia, but no oxygen . solar energy reaching the ground included high levels of UV radiation
simple single cells formed, possibly around volcanic geothermal vents on the seabed where the warm temp & rich mix of biological processes more likely
Archea were single celled organisms similar to bacteria. they still survive in many habitats, especially the oceans . some are anaerobic, such as methanogenic archea that live in intestines and marshes

KEY PRINCIPLES
- the structure and movement of earth, and its position in the solar system, control the abiotic conditions on earth that make life possible
- the presence of life has changed the conditions of earth and made it more suitable for life to become more varied and abundant
- living systems have responded to environmental changes, such as increasing intensity of sunlight . This has maintained the conditions that allow living organisms to survive .
