Deep phylogeny, ancestral groups and the four ages of life.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences - 12 Jan 2010

Cavalier-Smith Thomas

Abstract excerpt

Organismal phylogeny depends on cell division, stasis, mutational divergence, cell mergers (by sex or symbiogenesis), lateral gene transfer and death. The tree of life is a useful metaphor for organismal genealogical history provided we recognize that branches sometimes fuse. Hennigian cladistics emphasizes only lineage splitting, ignoring most other major phylogenetic processes. Though methodologically useful it...
