In Chapter 7 we discussed how "in 1997, archaeologists discovered a large number of similar bones from about 400,000 years ago at the bottom of a deep pit in the Sima de los Huesos cave at Atapuerca in Northern Spain." Curiously, similar burial sites have been hard to come by in Africa, but a new discovery extends the time frame for ritual burials in Africa at least back to 100,000 bce.
