| However, each tribe individually is either paraphyletic or polyphyletic with respect to most recent songbird classifications. |
|
| Two major clusters and four subgroups indicate that the paralogous C. cinereus rcb genes are polyphyletic and diverge through several lineages. |
|
| A simple form taxon, such as Chuaria circularis, may embrace a polyphyletic array of organisms that includes cyanobacteria as well as protists. |
|
| Loriciferans were originally assigned to the paraphyletic or polyphyletic group called Aschelminthes. |
|
| Later, however, a morphological analysis suggested that the Hardella complex constitutes a polyphyletic group. |
|
| Groups that do not contain the common ancestor, and therefore had two separate origins, are said to be polyphyletic. |
|
| The taxonomy of the group is not well resolved, with many family-group taxa considered paraphyletic or polyphyletic, and several subfamilies are unplaced at the family level. |
|
| The present study, as well as previous molecular studies, suggest that the oegopsid squids represent a polyphyletic group with uncertain phylogenetic affinities. |
|
| They do not represent a distinct taxon or systematic grouping, but instead have a polyphyletic relationship. |
|
| Using this scheme, the protozoans and algae are clearly polyphyletic. |
|
| As these three groups do not have a common multicellular ancestor, the seaweed are in a polyphyletic group. |
|
| The three largest genera, Carpodacus, Carduelis and Serinus were found to be polyphyletic. |
|
| It has been suggested that zebras are polyphyletic and that striped equids evolved more than once. |
|
| Such polyphyletic grades, which would put whales together with fish or birds together with bats, have generally been abandoned as soon as they were recognized. |
|
| However, plants outside this tribe are sometimes called thistles, and if this is done thistles would form a polyphyletic group. |
|
| Until the 21st century, most gulls were placed in the genus Larus, but this arrangement is now known to be polyphyletic, leading to the resurrection of several genera. |
