Artificial symbiogenesis and differing reproduction rates
Symbiosis is the phenomenon in which organisms of different species live together in close association. Symbiogenesis is the name given to the process by which symbiotic partners combine and unify. This letter reconsiders previous work using the NKCS model of coevolution to explore symbiogenesis. In particular, the role of different replication rates between the coevolving partners is considered. This is shown to provide a broader scope for the emergence of endosymbioses and subsequent horizontal gene transfers. © 2009 Massachusetts Institute of Technology
On cellular darwinism: Mitochondria
© 2016 Massachusetts Institute of Technology. The significant role of mitochondria within cells is becoming increasingly clear. This letter uses the NKCS model of coupled fitness landscapes to explore aspects of organelle-nucleus coevolution. The phenomenon of mitochondrial diversity is allowed to emerge under a simple intracellular evolutionary process, including varying the relative rate of evolution by the organelle. It is shown how the conditions for the maintenance of more than one genetic variant of mitochondria are similar to those previously suggested as needed for the original symbiotic origins of the relationship using the NKCS model
