PHYLOGENETIC SYSTEMATICS FOR PHYCOLOGY
Journal of Phycology, 1989This brief review of phylogenetic systematics introduces basic terminology but concentrates on actively debated issues in the theory of phylogenetic ...

Phylogenetics and Systematics in a Nutshell
2020During the last 50 years, phylogenetic systematics has suffered a substantial transformation in philosophy and methods. Systematics has gone from been a merely descriptive discipline to a scientific theory encompassing solid evolutionary principles capable of inferring robust and replicable historical hypothesis about the interrelationships of taxa ...

Structuralism in Phylogenetic Systematics
Biological Theory, 2010Systematics based solely on structuralist principles is non-science because it is derived from first principles that are inconsistent in dealing with both synchronic and diachronic aspects of evolution, and its evolutionary models involve hidden causes, and unnameable and unobservable entities. Structuralist phylogenetics emulates axiomatic mathematics

Phylogenetic systematics of the nymphaeales
The Botanical Magazine Tokyo, 1987A cladistic analysis was applied to reveal the phylogenetic relationships among the Nymphaeales. Seventeen out of twenty three characters in gross morphology, anatomy and palynology were analyzed, for their evolutionary polarities. From the results of the present analysis, the phylogenetic status of each genus and their relationships were clarified: 1 ...

Methods of systematic analysis: The relative superiority of phylogenetic systematics
Origins of Life, 1984The superiority of cladistic methods to both synthetic and phenetic methods is briefly advanced and reviewed. Cladistics creates testable hypotheses of phylogeny that also give a highly informative summary of available data. Thus it best fits the criteria for a method for determining the general reference classification in biology.

The Future of Phylogenetic Systematics
2016Willi Hennig (1913–76), founder of phylogenetic systematics, revolutionised our understanding of the relationships among species and their natural classification. An expert on Diptera and fossil insects, Hennig's ideas were applicable to all organisms.

Post-molecular systematics and the future of phylogenetics
Trends in Ecology & Evolution, 2015The time is past when a research program in systematics should be based on only a few genes, extant taxa, and ultrametric trees. Cheap genome sequencing, powerful statistical methods, and new fossil discoveries promise to reinvigorate research programs in evolutionary biology.

Arbitrarily amplified DNA in systematics and phylogenetics
ELECTROPHORESIS, 1995AbstractDifferent polymerase chain reaction (PCR) based techniques which use single primers of arbitrary sequence have become prominent and powerful tools for taxonomic and genealogical studies. While the use of arbitrarily amplified DNA (AAD) markers for the identification of lower taxonomic units (e.g. at the species level) has been proven to be more
