Archaeologist Jacques Reinhold and his wife discovered the oldest proof of human sacrifice in Africa:
The tomb of a 5,500-year-old man surrounded by three sacrificed humans, two dogs and exquisite ceramics were exhumed north of Khartoum by Neolithic expert Jacques Reinhold and his 66-year-old Austrian wife. [...]
The archaeologist, who has led the excavation for several months, described the tomb as the most important Neolithic find in Africa since the 1990s.
That period -- which Reinhold calls the first global revolution -- marks the period when man evolved from hunter gatherers into farmers and producers, forever changing the structure of human society.
He says the find is nearly 1,000 years older what many consider Sudan's most spectacular discoveries of human sacrifice -- scores of bodies buried together.
