Phylogeny of lanternfishes based on mitochondrial gene order

Lanternfishes show a high degree of unique gene orders in the mitochondrial genome compared to most other vertebrates. All of the gene-order changes are informational concerning clade delimitation and show an unprecedented empirical case of DNA sequences and gene order rearrangements corroborating phylogenetic history. However, one unique gene order complicates the phylogeny and witness an early duplication event. This talk deals with the problems associated with gene order rearrangements in reconstructing phylogeny.
