Abstract

Lake Tanganyika harbors numerous endemic species of extremely diverse cichlid fish that have been classified into 12 major taxonomic groups known as tribes. Analysis of short interspersed element (SINE) insertion data has been acknowledged to be a powerful tool for the elucidation of phylogenetic relationships, and we applied this method in an attempt to clarify such relationships among these cichlids. We studied insertion patterns of 38 SINEs in total, 24 of which supported the monophyly of three clades. The other 14 loci revealed extensive incongruence in terms of the patterns of SINE insertions. These incongruencies most likely stem from a period of adaptive radiation. One possible explanation for this phenomenon is the extensive incomplete lineage sorting of alleles for the presence or absence of a SINE during successive speciation events which took place about 5-10 MYA. The present study is the first to report the successful application of the SINE method in demonstrating the existence of such possible "ancient" incomplete lineage sorting. We discuss the possibility that it might potentially be very difficult to resolve the species phylogeny of a group that radiated explosively, even by resolving the genealogies of more than 10 nuclear loci, as a consequence of incomplete lineage sorting during speciation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
