The Coming of Age of Molecular Systematics

Science, 1998
For decades, taxonomists examined the insides and outsides of organisms to gain clues about their evolutionary relationships. Recently, molecular biology has provided a new set of characteristics for examination--gene sequences. But constructing evolutionary trees by comparing the sequences of the most commonly used gene, a gene for ribosomal RNA, is ...

Molecular systematics of the genus Neotoma

Molecular Phylogenetics and Evolution, 2002
DNA sequences from the mitochondrial DNA cytochrome-b gene were used to infer the systematic relationships of 13 species of wood rats (genus Neotoma). Parsimony, likelihood, and neighbor-joining analyses produced similar topologies in most cases and produced six systematic conclusions.

Computational problems in molecular systematics

1994
The development of extremely powerful computer programs and the ready availability of microcomputers has revealed several computational problems with data analysis. These problems occur in the handling of systematic data in general and molecular systematic data in particular.

Retroposon Mapping in Molecular Systematics

2004
Advances in genome sciences are demonstrating the dynamic nature of noncoding DNA regions, which are comprised largely of repetitive elements with no apparent function. Retroposons are one class of mobile genetic elements that amplify and move about the genome via a copy-and-paste mechanism that employs an RNA intermediate.

Eumycetozoans and molecular systematics

Canadian Journal of Botany, 1995
Eumycetozoans, the myxomycetes, protostelids, and dictyostelids, were first hypothesized to be a monophyletic group by L.S. Olive, who suggested that the primitive members of the group were similar to some of the extant protostelids. A review of morphological evidence supporting some aspects of this hypothesis is presented along with explicit ...

Molecular biology and systematics

1994
Abstract Sequence data from both the nuclear and plastid encoded small subunit ribosomal RNA (ssu rRNA) gene have been used to infer the phylogenetic position of the haptophyte host cell and its plastid. Both are in distinct lineages that do not share a recent evolutionary history with their chromophyte counterparts.

Molecular Systematics of the Primates

1976
A large body of comparative macromolecular data bearing on primate systematics is now available. There does not exist, however, any consensus as to just what that bearing is or what it should be. We hope that this chapter can contribute toward such a consensus.
