The sample size is exceedingly small, but there is a suggestion that our molecular data are separating populations within both species that have distinctly different habitats.
T. thynnus and T. orientalis are considered to be very closely related and have been separated as sub-species until recently when molecular data, especially mitochondrial DNA, corroborated their separate species status [ 4, 56].
The Shape package can be divided into a few separate units; molecular data and control parameter input, ga search together with the energy evaluation back-end, and result clustering.
Here, we utilized multiple separate sources of molecular data, mtDNA, nuclear sequences, and microsatellites, to delimit species under a polytypic species concept (PTSC) and estimate the frequency and genomic extent of introgression in a Neotropical genus of cichlid fishes (Cichla).
In the view of molecular data, HGssp contains two groups, HGsspa and HGsspb, separated by an important genetic distance (0.06240 0.09719) in the range of those observed between species.
We find that, based on extensive molecular data and an inclusive species concept, 8 separate biological entities should be recognized rather than the 15 described species of Cichla.
The molecular data indicate that humans and chimps went their separate ways only about 4.5 million years ago.
Inclusion of Tesia in Cettia might have been more appropriate based on the molecular data, although we tentatively prefer to treat Tesia as a separate genus, acknowledging that it is a morphologically well-defined group of long standing.
Molecular data are also extremely variable – suggesting that these isolated populations have long been separated.
The genus was once grouped with other Old World rats and mice of the subfamily Murinae in the family Muridae, but analyses of dental and molecular data suggest that the African spiny mice form a distinctive and separate subfamily, Acomyinae.
