Archaea was originally thought to be just another form of bacteria, but archaea is a much simpler form of life, simpler than a single-celled organism which nevertheless contains DNA, the gene-code of life.

Bacteria may be the largest category of life, but archaea may be the oldest. Archaea is a form of life which can survive in extremely hot environments such as boiling water, and inside volcanos or geysers. It can live in rocks miles down, deep within the earth at extreme pressures. It likes the heat so much that it has earned the nickname "thermophile", which means "loving heat", and it would probably freeze to death at ordinary room temperature.
Archaea requires neither sunlight for photosynthesis as do plants on Earth, nor oxygen as do animals. Archaea "breathes" carbon dioxide, nitrogen and hydrogen, chemically transforms them, and gives off methane gas as a waste product.
Planets which contain an environment wherein archaea might survive include Venus, the past environment of Mars, Jupiter, Saturn, and Jupiter's moon Io.
Archaea is a form of life which loves the heat! It likes to live in boiling water, like the geysers of Yellowstone Park, and inside volcanoes.

Archaea was originally thought to be just like bacteria, but archaea is a much different and simpler form of life. It may also be the oldest form of life on Earth!
