iterative evolution A repeated evolution of similar or parallel structures in the development of the same main line. There are many examples of iterative evolution in the fossil record, spanning a wide range of groups. This evolutionary conservatism is probably due to the overriding morphogenetic control exerted by certain regulatory genes.
