coevolutionEvolution of those structures and behaviours within a species that can best be understood in relation to another species. For example, some insects and flowering plants have evolved together: insects have produced mouthparts suitable for collecting pollen or drinking nectar, and plants have developed chemicals and flowers that will attract insects to them. Parasites often evolve and speciate with their hosts. Coevolution occurs because both groups of organisms, over millions of years, benefit from a continuing association (symbiosis) and will evolve structures and behaviours that maintain this association. |

Evolutionary systems tend to coevolve as minute advances in one system's design are made possible only by subtle alterations in another. Perhaps it is unfair to consider it hedging when he says, "I shall not be overly surprised if in the coming decades, some experimental group creates such life anew, snapping into existence in some real chemostat, creating protocells that coevolve with one another. |
