Rates and patterns of mitochondrial gene evolution are analyzed at different taxonomic levels within this avian order, and evidence is adduced for and against the nearly neutral theory o ...

Particularly, the phylogenetic relationships between muscicapoidea and sylvioidea are complex, and their taxonomic boundaries have not been clearly defined.
