Carl R. Woese, "On the evolution of cells" (2002)
Różnorodność komórek wymaga przyjęcia kilku wyjściowych warunków ewolucji. Istniejące życie pochodzi od trzech rożnych typów komórek.
"Evolving the cell requires evolutionary invention of unprecedented
novelty and variety, the likes of which cannot be generated by any familiar
evolutionary dynamic....Thus, what needs explaining is not why the major
cell designs are so similar, but why they are so different. This
apparent contradiction can be resolved by assuming that the highly diverse
cell designs that exist today are the result of a common evolution in which
each of them began under (significantly) different starting
conditions."
[...]
"Extant life on Earth is descended not from one, but from three distinctly
different cell types."

8745-6.
