How many of you have pondered upon the origin of humanity? Or who could have been the oldest ancestor to mankind? Or how we are all related to that ancestor?
I know some will say Adam and Eve… but what if it was Lucy and someone else instead? What if it was not somewhere in the Middle East but rather on the African continent?
Well, today, we will be talking about Lucy, the first human ancestor discovered in Ethiopia, in Africa, the cradle of humanity.
Lucy was discovered in 1974 in Africa, at Hadar, a site in the Awash Valley of the Afar Triangle in Ethiopia, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History . In Ethiopia she is known as Dinkinesh, meaning the marvelous one in Amharic. The Lucy specimen is an early australopithecine and is dated to about 3.2 million years ago. At the time of the findings, it was the most ancient early human – or hominin – ever found. It was also the most complete: 40% of the skeleton had been preserved.
Now, you might ask, why is she called Lucy? Well, because the Beatles’ song “Lucy in the Sky with Diamonds” was playing on the radio when the archaeologists found her remains. Thus the name Lucy. Lucy belongs to the species of Australopithecus afarensis; afarensis for the Afar region of Ethiopia where she was found. She is one of the most important fossils ever discovered. Her discovery helped solidify the idea that Africa was the cradle of humanity, and a crucial hub for human evolution. Before Lucy, the skeleton of the Taung child dated to about 2.8 million years old had been found in South Africa in 1924, but European archaeologists and scientists refused to admit (as always) that Africa could be important in the study of human evolution. As always, they thought that Europe and Asia were the centers. Aren’t we tired of this Eurocentric view of the world which pretends to give meaning to everything it does not understand? Oh Mama Africa, your beauty and splendor is truly too much for these people that they have to keep denying your place and importance in the world!
Lucy was an upright walker, i.e. she walked standing up, thus dating the bipedalism observed in humans to at least 3.2 million years. She was only about 1 meter tall (3.5 feet). Lucy was a full-grown adult, because she had wisdom teeth and her bones had fused. Unlike modern humans, it would seem that she had grown to full size very quickly, and was about 12 years old when she died. From a 2006 study, the findings of a 3-year-old Australopithecus afarensis suggested that their brains reached their full size much earlier than modern human’s does. Lucy was ape-like in appearance and brain size, but could walk upright like more advanced hominins that lived later like the Taung child (2.8 million years) or the Australopitecus sediba (2.2 million years old). She had powerful arms and long curved toes that paleontologists think allowed her to climb trees as well as walk upright.
Lucy’s finding marked a turning point in our understanding of humanity, and the human lineage. She is a treasure, and although older skeletons have since then been found like the Kenyantropus platyops (3.5 million years) or the Ardipithecus (dated 4.4 million years), she remains a treasure. No wonder, Ethiopians call her Dinkinesh or “you are marvelous” or “marvelous one“, for Lucy truly is marvelous as she has allowed to place Africa back at the center as the cradle of humanity (Africa was always at the center, but some Eurocentric views would not let her shine). If you are ever in Addis Ababa, please do not forget to visit her (her cast) at the National Museum of Ethiopia . Enjoy!
