| 41. | Despite general agreement on phylogeny, the taxonomy is still under debate.
|
| 42. | This genus has been investigated using DNA phylogeny and undescribed species exist.
|
| 43. | These similarities are partially a result of their similar phylogenies.
|
| 44. | The species were differentiated based on the phylogeny containing the four clades.
|
| 45. | Molecular phylogeny indicates it may be a basal member of the Urechinina.
|
| 46. | Regarding internal phylogeny, at present, resolution is insufficient.
|
| 47. | Phylogenetic methods examine evolutionary histories of genes involved and identify conflicting phylogenies.
|
| 48. | Below is a cladogram from Conrad ( 2015 ) with this phylogeny:
|
| 49. | Further preparation of the fossils might provide additional information about its phylogeny.
|
| 50. | In 1998 the Angiosperm Phylogeny Group published a taxa.
