Timmermann argued that parasites were associated with their hosts by descent and that this produced congruent host and parasite phylogenies. In contrast, Mayr argued that parasites were often associated by colonization and that this led to incongruence between host and parasite phylogenies. To test these differing views, Adrian Paterson, Russell Gray and Graham Wallis derived a procellariiform phylogeny. This tree is here compared with Timmermann's tree based on the relationships of feather lice. Timmermann's tree is more similar to the seabird phylogeny that would be expected by chance. Thus, support is found for the 'comparative parasitology' approach.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><accession-num><style face="normal" font="default" size="100%">36877</style></accession-num><notes><style face="normal" font="default" size="100%">A historical look at the comparitive parasitology debate through the eyes of Gunther Timmermenn and Ernst Mayr, via the recording of a discussion after a symposium talk. The discussion is followed by an analysis of Timmermanns lice data to construct a phylogeny of Procellariiform birds. For comparison a host phylogeny based on mitochondrial 12S ribosomal RNA sequence data was used. Similarity between the trees was determined using COMPONENT, and they found that the trees were much more similar than would be expected due to chance alone (P=0.001).pdfJournal</style></notes></record></records></xml>
