The study of the fangs of Ardipithecus, found in Ethiopia, has led some North American anthropologists to affirm that the three are of one gender.

There is a great difficulty in making classifications in this field due to the shortage of fossils and, in addition, often, to their distancing. The discovery of Ethiopia showed that in the three there were elements of the same type, canines. In the shape and in the appearance and thickness of the enamel similar were observed, and hence it is deduced that they should be classified in the same genus.

Some anthropologists, however, affirm that the similarities between the teeth are not enough to change the opinion that we have so far and that there are differences between the teeth of the three.
