The rudiments of evolutionary, or phylogenetic, plant systematics existed even before the revolution in biology produced by C. Darwin. For example, the Russian botanist P. F. Gorianinov as early as 1834 advanced the idea of a general evolution of nature—from simple forms to more perfect ones...
The cladistic revolution of the 1970s and 1980s constituted a major paradigm shift in biology and systematics, with the Evolutionary system falling out of favour and being replaced by the one. Cladistics is based not on morphological similarity (as in the Linnaean system and more recently ...
In subject area: Biochemistry, Genetics and Molecular Biology Molecular systematics came into play when genetic data could be used to separate groups of individuals or local populations belonging to one species that could not be distinguished by their extrinsic characters. ...
From the biological viewpoint the tasks of systematics may be subdivided into analyses of infraspecific variation (both intra- and interpopulation studies), the separation of genetic from environmental effects on the phenotype, the definition of species (and possibly subspecies), the definition of ...
In understanding biodiversity, one must understand that taxonomy and systematics work together, although the two terms are often confused. Divergence between the modern concepts of systematics starts at the definition given to the taxa they ... MD Bargues,CJ Schofield,Jean-Pierre Dujardin * - 《Ame...

A systematic classification of π-turns of both hydrogen-bonded and non-hydrogen-bonded types is necessary in the light of what has been done for shorter α-turns for a proper appraisal of turns in protein structures. By conventional definition π-turns are six-residue long, in which the CO...
