    What did the different branches of our distant hominid cousins have in common? To answer this question, 2 fossil skulls were scanned on 20 February by a machine called XtremeCT, initially designed for space medicine. The results of this unique scientific initiative were presented last week. A few millimetres under the surface of our teeth is an interface between two types of tissue: enamel, which gives us our gleaming white smile; and dentin, which underlies the enamel. The features of this interface are pretty constant within the same species, since they are genetically encoded.
