Excavations at Sima de los Huesos. Palaeontologists excavating hominin fossils from the Sima de los Huesos (Pit of Bones) site, Sierra de Atapuerca, Spain. Thousand of bones and bone fragments, from at least 28 individuals, have been excavated from this site since its discovery in 1984. Skulls from the site, which date to the middle Pleistocene around 430,000 years ago, exhibit a mixture of Neanderthal and more primitive features. The jaw and facial bones are Neanderthal-like, while the cranium is primitive. This suggests that characteristic Neanderthal features evolved separately from each other, an evolutionary model known as the accretion model.
