Re: The duck that ruled the world.



Each ratite cladogram I saw showed different points of view.
If Ratites existed in Gondwana before its breakup, each group must have
evolved at a different "block"
South America - Rheiformes and Tinamiformes (I'm using the traditional names
for the orders, Ok?)
Africa - Struthioniformes?
India - ? (the origin of European Remiornis? Struthioniformes?)
Madagascar - Aepyornithiformes?
Australia - Casuariiformes
New Zealand - Dinornithiformes + Apterygiformes
