On this day, an American anthropologist Donald Johanson woke up feeling lucky. His intuition didn’t lie: two seasons of research in an Ethiopian desert finally came to fruition. Next to the Hadar village 150 km from Addis Ababa, he and his colleague Tom Gray found approximately 40% of an Australopithecus’s skeleton. In the evening, the anthropologists celebrated their victory to the “Lucy in the Sky with Diamonds” song by their beloved The Beatles. In excitement, the three-and-a-half-million-year-old Australopithecus was named Lucy. Under this name, she took her place in the history of science. It should be reminded that the first Australopithecus was also found in Africa – the root “austral” means “southern.”
