Systematic errors in phylogenetic trees [PDF]

open access: yesCurrent Biology, 2021
The effort to reconstruct the tree of life was revolutionized by the use of sequences of proteins and nucleic acids. Phylogenetic trees are now routinely inferred using hundreds of thousands of amino acid or nucleotide characters. It thus seems surprising that many aspects of the tree of life are still controversial; conflicting results between large ...

Phylogenetic systematics of Juncaceae. [PDF]

open access: yesAm J Bot
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within

ONTOGENY AND PHYLOGENETIC SYSTEMATICS [PDF]

open access: yesCladistics, 1985
Abstract— Dedifferentiation, paedomorphosis, and the insertion and deletion of developmental stages make it impossible to deduce the genealogical hierarchy from only ontogenetic transformation series. Like the outgroup criterion, ontogenetic character precedence is not theory‐neutral and to use it to deduce genealogy requires certain assumptions.If ...

Information and Phylogenetic Systematic Analysis [PDF]

open access: yesInformation, 2015
Information in phylogenetic systematic analysis has been conceptualized, defined, quantified, and used differently by different authors. In this paper, we start with the Shannon Uncertainty Measure information measure I, applying it to cladograms containing only consistent character states.
