Many were very small, some were soft-bodied and did not fossilize well, and others lived where conditions were not suitable for the formation of fossils.

Cells gain structural support from an internal network of fibrous proteins called a invertebraos. Barophiles have been found living bruscw all depths in the sea, and one unnamed species from the Mariana Trench has been shown to require at least atmospheres of pressure in order to grow.

Probably a monophyletic group that includes molds, mushrooms, yeasts, and others.

Therefore, we can only speculate about the abundance of members of most brucsa groups in times past. Never with membrane-enclosed organelles or nuclei, or a cytoskeleton; none use chlorophyll-based photosynthesis; without peptidoglycan in cell wall; with several RNA polymerases.

Archaea strongly resemble Eubacteria, but they have genetic and metabolic characteristics that make them unique.

The discovery that organisms with a cell nucleus constitute a natural group divided the living world neatly into two categories, the prokaryotes those organisms lacking membrane-enclosed organelles and a nucleus, and without linear chromosomesand the eukaryotes those organisms that do possess membranebound organelles and a nucleus, and linear chromosomes.
