However, components may change considerably in the process of their coevolution. Other examples of symbiosis 1. eucaryotic cell originated from a symbiosis of several bacterial species . Mitochondria are bacteria that became specialized as energy producers. This is a transmission electron micrograph of rat liver cells. Part of the nucleus is in the right lower corner.
Circular objects are mitochondria.
Symbiosis of leaf-cutter ants and fungi . More examples 4. Evolutionary stability of cooperation Metasystem transition requires cooperation of components. The major obstacle on the way of cooperation is possible evolutionary instability. A and B that produce resources for each other.
