“Every time we found a human burial, we would find stranger and stranger animals.”
During the new series, Dr Friedman takes viewers to the location of the burials, where she has found the remains of hippopotami, hartebeest, elephants, baboons, and African wildcats.
She said during the documentary: “So here, in essence, we have the world’s first zoo and it dates back over 6,000 years.”

She said: “Although all these animals have obviously been buried, we see that they sustained injuries that were healed and had to be healed under human care.
