In 2007 Torsten Struck and colleagues compared 3 genes in 81 taxa, of which 9 were outgroups, in other words not considered closely related to annelids but included to give an indication of where the organisms under study are placed on the larger tree of life. For a cross-check the study used an analysis of 11 genes (including the original 3) in 10 taxa. This analysis agreed that clitellates, pogonophorans and echiurans were on various branches of the polychaete family tree. It also concluded that the classification of polychaetes into Scolecida, Canalipalpata and Aciculata was useless, as the members of these alleged groups were scattered all over the family tree derived from comparing the 81 taxa. In addition, it also placed sipunculans, generally regarded at the time as a separate phylum, on another branch of the polychaete tree, and concluded that leeches were a sub-group of oligochaetes rather than their sister-group among the clitellates. Rouse accepted the analyses based on molecular phylogenetics, and their main conclusions are now the scientific consensus, although the details of the annelid family tree remain uncertain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What subtypes of polychaetes were useless classifications, according to the 1997 study?
Ah, so.. unanswerable

There is no green pigment in green eyes; like the color of blue eyes, it is an optical illusion; its appearance is caused by the combination of an amber or light brown pigmentation of the stroma, given by a low or moderate concentration of melanin, with the blue tone imparted by the Rayleigh scattering of the reflected light. Green eyes are most common in Northern and Central Europe. They can also be found in Southern Europe, West Asia, Central Asia, and South Asia. In Iceland, 89% of women and 87% of men have either blue or green eye color. A study of Icelandic and Dutch adults found green eyes to be much more prevalent in women than in men. Among European Americans, green eyes are most common among those of recent Celtic and Germanic ancestry, about 16%.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where are green eyes most common?
Ah, so.. Northern and Central Europe

The city's FM radio band features RTÉ Radio 1, RTÉ 2fm, RTÉ lyric fm, RTÉ Raidió na Gaeltachta, Today FM, 4fm, Newstalk and the religious station Spirit Radio. There are also local stations such as Cork's 96FM, Cork's Red FM, C103, CUH 102.0FM, UCC 98.3FM (formerly Cork Campus Radio 97.4fm) and Christian radio station Life 93.1FM. Cork also has a temporary licensed city-wide community station 'Cork FM Community Radio' on 100.5FM, which is currently on-air on Saturdays and Sundays only. Cork has also been home to pirate radio stations, including South Coast Radio and ERI in the 1980s. Today some small pirates stations remain. A number of neighbouring counties radio stations can be heard in parts of Cork City including Radio Kerry at 97.0 and WLR FM on 95.1.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Cork Campus Radio change to?
Ah, so..
UCC 98.3FM
