Cospeciation, also sometimes called co-cladogenesis, is a macro-scale process in biology where two species each split into two or more new species, and they do it together, because they are linked in some way. The process of cospeciation is explored here, as well as some examples chosen from the published scientific literature. We touch on some of the kinds of biological systems that can give rise to cospeciation: interactions between host and parasite species, symbiotic relationships, and host–pathogen dynamics. The article also describes some of the effects of cospeciation on inferences we can make in evolutionary biology, particularly in phylogenetics and cophylogenetics.
