Current evidence suggests that eukaryotes are a natural group, defined by the unique trait of a nucleus and linear chromosomes, whereas Eubacteria and Archaea may not be natural groups. Over a million species of living animals have been described, but estimates of how many living species remain to be discovered and described range from lows of 10—30 million to highs of — million.
The oldest evidence of possible life on Earth consists of 3. Never with membrane-enclosed organelles or nuclei, or a cytoskeleton; none are methanogens; some use chlorophyll-based photosynthesis; with peptidoglycan in cell wall; with a single known RNA polymerase. The following account briefly summarizes the early history of life and the rise of the invertebrates. Barophiles have been found living at 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.
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.
