Dromaiidae
The dromaiidés (or Dromaiidae ) train a family of large birds inapt for the flight which include/understand nothing any more but one species of émeu and three species of Casoar. Their legs carry only 3 toes. They have long legs and a long neck.
One finds them in Australia, in wood the semi-arid lights and plains.
Evolution
Move form a distinct subfamily, characterized by legs adapted to the race. As at all the others ratites, several disputed theories are opposed concerning their evolution and their interrelationships. With regard to their family, it is particularly interesting to know which enters move them and the casoars are the most primitive form: the seconds are generally supposed to preserve characteristics plésiomorphes, but this is not paramount; the data on the fossils are indeed ambiguous, and the actual position of genomic does not allow sufficiently comprehensible analyzes. A combination of all these approaches with, at least, of the considerations on the plate tectonics is necessary to the resolution of this problem.The number of described species of casoars, based on minor differences as for the shape of the helmet and with the variations in colors, is very broad. Currently, however, only 3 species are proven, and several authorities recognize only few species, even none.
The description of fossils of casuariformes is interesting, but not very wide. With regard to species fossilesde Dromaius and of Casuarius, to see their pages of kind.
