REPLICATION, VARIATION, FITNESS. “Evolution as a process requires the presence of three simple elements: replication, variation and differential fitness. Replication allows for inheritance, and in particular the inheritance of variations, introduced by different mechanisms of mutation. These variations are then selected for or against via the competition of individuals over limited resources. The competition leads to differential fitness.” Don’t forget some reproductive isolation by speciation.
