Placement at mid trophic level (predator and prey) Prokaryotic ancestor gave rise to bacteria, archaea, and eukarya.

Machinery for synthesis and degradation of molecules. Evolution of life in alkaline deep sea vents = reducing environment so (cid:1) (cid:1) energy available, suitable for thermophiles (cid:1) (cid:1) Evolution of photosynthesis = special pigments required, changed. Earth has only had accumulated oxygen for ~2 billion years (1/2 of existence) (cid:1) (cid:1) (cid:1) Prokaryotic (asexual) common biochemical properties, phylotypes need 97% rna similarities (cid:1) Polyphyletic a bunch of descendants with many ancestors. Domain, supergroup, kingdom, phylum, class, order, family, genus, species. Virus: a genome that replicates itself within a host cell by directing machinery to synthesize viral nucleic acids and proteins. Lack cellular features (membrane, cytoplasm, ribosomes, enzymes)
