The new evidence, based on jawbones, does not rule out the possibility that a facial morphology such as that of Homo antecessor is a better candidate for the common ancestor of Homo sapiens, Neanderthals and Denisovans. It does confirm differences between fossils from North Africa and Europe around 800,000 years ago, highlighting the complexity of this still little-known period.
In any case, a well-known aphorism in paleoanthropology comes to mind, which says that ‘while the skull is God's creation, the jaw is the devil's work’; we will surely have to wait to discover what the skulls of these individuals looked like in order to clarify possible relationships with H. antecessor.
