Powerful tests of adaptational hypotheses can be made in the context of well-supported cladograms by investigating the most parsimonious transformation of intrinsic or extrinsic factors to explain their distribution across taxa in a cladogram. Such tests are used here to discover patterns of life-history evolution in leeches; in particular in relation to exploitation of terrestrial and aquatic habitats, parental care and resource utilization. Moreover, the relationships among leeches… CONTINUE READING
