The small family of elephant shrews or sengis (order Macroscelidea) represents a monophyletic radiation endemic to Africa and which was long placed within the polyphyletic
group 'Insectivora' (Rathbun & Rathbun, 2006).
Taxonomic revisions in the polyphyletic
genus Tabebuia s.l.
Thus, 3 of these 16 STs did not cluster the isolates properly inasmuch as these STs were polyphyletic
. In summary, for the Oxford scheme we demonstrated that some STs form polyphyletic
groups because 4 of the 7 loci have signals of recombination (Appendix Table 2), whereas for the Pasteur scheme, we noted a serious lack of resolution for some STs because the loci used only by this scheme have the lowest levels of genetic diversity (Appendix Table 2).
Having made this discovery, the team now wants to understand whether angiosperms are either monophyletic -- which would mean Nanjinganthus represents a stem group giving rise to all later species -- or polyphyletic
, whereby Nanjinganthus represents an evolutionary dead end and has little to do with many later species.
Neobisiinae was recovered as polyphyletic
in our analysis, due solely to the placement of Parobisium charlotteae outside of an otherwise well-supported clade containing all other members of this subfamily (Fig.
The genus Acacia sensu lato is considered polyphyletic
(Pedley, 1986; Maslin et al., 2003; Seigler et al., (2006a) as supported by molecular studies (Miller and Bayer, 2001; Luckow et al., 2003), including a series of subgroups.
Brown rot fungi are polyphyletic
, and while some characteristics such as early hemicellulose removal are common among brown rot fungi [11, 12], their genomes harbor significant variability [13,14] and brown rot fungi can be found in a wide variety of niches in nature .
The insufficiency of data on shell fabric of this polyphyletic
order comprising superfamilies of uncertain origin is obvious.
HLJ, JL and other north east sequences are polyphyletic
This rendered the genus Dendrocryphaea polyphyletic
as is currently circumscribed.
 proposed a polyphyletic
migration operator to utilize as many as four habitats' features to construct a new solution vector, which can generate new features from more promising areas in the search space.
viridis (Peters, 1852), originally defined just morphologically, were each shown to consist of three mitochondrial lineages in a polyphyletic
arrangement (Trujillo et al.
