Perspectives

Biology Recapitulates Phylogeny

David M. Hillis

Phylogenetic analysis--the study of the evolutionary relationships of organisms--is enjoying something of a renaissance. In his Perspective, Hillis discusses this trend, exemplified in this issue in two reports by Pierce et al. (p. 256) and Becerra (p. 253) that examine the evolution of enzymes and host-pest pairs and in an article by Huelsenbeck et al. (p. 227) that discusses current methods of phylogenetic analysis.
