At the northern end of the Great Rift Valley is the Danakil Depression, where the 3.2 million-year-old fossil Lucy was unearthed.
One of the oldest hominids ever found, she was named after the Beatles’ hit "Lucy in the Sky with Diamonds", which was playing on loop at the expedition camp the night of her discovery.
She was also given an Amharic name, Dinkenesh, meaning "You are wonderful".
