“Spain virtually invented paleontology”

Fresh from the discovery that an Atapuerca specimen has the oldest human DNA in the world, site director Juan Luis Arsuaga on success and his frustrated ambition to be a caveman

When Juan Luis Arsuaga was growing up in the 1960s, he says he wanted to be a caveman, which probably explains why he studied paleontology. He later joined the team excavating the cave complex at Atapuerca, near Burgos. Along with colleagues José María Bermúdez de Castro and Eudald Carbonell, he has just published the oldest DNA sequence in the world, taken from a 400,000-year-old femur found at Atapuerca and which suggests a link between Europe's hominids of the time and the little-known Denisovans, who until now were believed to have lived in southwestern Siberia, rather than the more widespread Neanderthals.

Question. What was Femur 13 like?
