A hierarchical structure describing the inter-relationships of species has\nlong been a fundamental concept in systematic biology, from Linnean\nclassification through to the more recent quest for a 'Tree of Life.' In this\npaper we use an approach based on discrete mathematics to address a ...

The very nature of the evolutionary process and the limitations of current phylogenetic reconstruction methods imply that parts of the tree of life might prove difficult, if not impossible, to resolve with confidence. Abstract As more complete genomes are sequenced, phylogenetic analysis is entering a...
A Phylogenetic tree demonstrates the hypotheses of the development and progression of life. They are only as accurate as of the data on which they have been rooted and demonstrated. The data comes from the research and studies that have biases up to some extent. Hence, the phylogenetic ...
