The term "species" has been a central tenet of biological belief since the early days of biology. But the concepts attached to the term have varied and often were not defined rigorously. The purpose of this paper is to investigate the biological species concept (BSC) : to consider its theoretical aspects, how one would actually delimit a biological species in nature, whether such species exist in nature, and whether the concept is of any unique value to the study of evolution. The classical… Expand
The debate about the biological species concept ‐ a review
TLDR
This paper summarizes the recent literature in relation to the ‘biological species concept’ (MAYR 1942) and concludes that the biological species concept needs not be changed or dismissed on the basis of the discussed criticisms. Expand
A unified concept of species and its consequences for the future of taxonomy
TLDR
The unified species concept is a natural outcome of a change in the general conceptualization of the species category that has been underway for more than a half-century and represents the more complete acceptance of the idea that species are one of the fundamental units of biology. Expand
THE SPECIES CONCEPT IN QUERCUS
TLDR
It is suggested that the classical species of Quercus may represent phyletic units in species-grade evolutionary advances, and a comparison between the biological species-concept and the classicalspecies-concept in quercus suggests why the classical concepts have been retained. Expand
A LOCAL FLORA AND THE BIOLOGICAL SPECIES CONCEPT
TLDR
A local flora is analyzed to determine whether polyploidy, apomixis, hybridization, and other deviations from regular sexual reproduction are sufficiently frequent in plants to make the biological species concept illusory, validating use of the sympatric situation as yardstick for the ranking of allopatric populations.

TLDR
There is a discrepancy between widely held perceptions of how species are delimited and the way species are actually delimited by taxonomists, and no support was found for the idea that Phylogenetic Species Concepts have caused a change in the ‘nature’ of species taxa. Expand
A Critique of the Biological Species Concept and Recommendations for a Phylogenetic Alternative
TLDR
The biological concept fails to provide unambiguous criteria for grouping organisms (or for assigning species rank), and as a consequence, biological species may not be monophyletic. Expand
An idealized concept of the true cladistic character
Abstract Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which suchExpand
Classes or Individuals? The Paradox of Systematics Revisited
TLDR
It is demonstrated that concepts on the evolutionary process are damaged when species are considered as evolutionary units, and it is shown that the equivalence between evolutionary and taxonomic units may also damage the practice of biological systematization. Expand
Species and “strange species” in zoology: Do we need a “unified concept of species”?
TLDR
In allopatry, the method of inference can be used and, in the absence of sufficient information, it is fully possible to use “by default” the “phylogenetic concept of species” or simpson. Expand
Species concepts and species delimitation.
TLDR
A unified species concept can be achieved by treating existence as a separately evolving metapopulation lineage as the only necessary property of species and the former secondary species criteria as different lines of evidence relevant to assessing lineage separation. Expand

Patterns and Populations
TLDR
It is suggested that in broad investigations of the patterns of interaction and relationship among organisms the artificial and stultifying fragmentation of population biology into divisions such as taxonomy, population genetics, and ecology should be ignored. Expand
COMMENTS ON THE DEFINITION OF GENERA
TLDR
It is suggested that all taxonomic categories must be in harmony with evolutionary concepts, and that the sole aim of taxonomy is to describe a series of categories based on resemblances and differences. Expand

TLDR
The authors discuss the problems of describing geographic variation data and develop statistical methods for categorizing sets of populations sampled from different localities and describe the approach of the simultaneous test procedures employed with these techniques. Expand

TLDR
The results indicate that serologically distinct human Mycoplasma species can also be distinguished by the homology techniques, and M. pneumoniae appears to be the most distinct of all human mycoplasmas, as shown by both homology and the high buoyant density value of its DNA. Expand
Folk Taxonomies and Biological Classification
TLDR
A sample of 200 native plant names from the Tzeltal-speaking municipio of Tenejapa, Chiapas, Mexico, was found to consist of 41 percent that comprised more than one botanical species, and over half of the names for which there was one-to-one correspondence were plants associated with Hispanic culture.
