Although controversy still exists regarding precise relationships within Paleognaths, especially within the ratites, most workers agree that tinamous are the basal sister taxon with respect to the remaining ratite birds.” Dyke 2003.

The most surprising result of the phylogenetic analysis is that the two groups of New Zealand ratites have different
origins, the moas representing an earlier divergence among ratites, whereas the kiwi more recently shared an ancestor
with the ostrich and the Australian ratites”

Although these data do not allow a presice placement or an estimate of divergence date, the elephant-bird is
clearly not the result of a recent divergence from the ostrich, or any other ratite lineage.”

The tight clustering of dates and lack of phylogenetic resolution, despite the long sequences, also suggests
that the derived ostrich, kiwi, and emu/cassowary taxa speciated rapidly, possibly in the remnant Gondwanan
landmass of Antarctica/Australia.”
