Resolving deep lineage divergences in core corvoid passerine birds supports a proto-Papuan island origin
It is well established that the global expansion of songbirds (Oscines) originated in East Gondwana (present day Australo-Papua), and it has been postulated that one of the main constituent groups, the “core Corvoidea”, with more than 750 species, originated in the first islands that emerged where N...

It is well established that the global expansion of songbirds (Oscines) originated in East Gondwana (present day Australo-Papua), and it has been postulated that one of the main constituent groups, the “core Corvoidea”, with more than 750 species, originated in the first islands that emerged where New Guinea is now located.
