Description: How old is the association between a given parasite and its host? Rod Page at the University of Glasgow tries to answer this question.
Announcement: Cospeciation and rates of evolution in lice and birds: a molecular approach Cospeciation and rates of evolution in lice and birds: a molecular approach A key question in the study of coevolution is the tempo and mode of evolution of the interacting partners. For example, how old is the association between a given parasite and its host? Is the association an ancient one, reflecting a long and intimate interaction between the two organisms, or is it a recent event due perhaps to a parasite colonising a new host? Answering these questions requires the comparison of evolutionary trees (phylogenies) for host and parasite (Fig. 1).
