A grand day for Science has taken place exactly 41 years ago!!

Let's all celebrate today's day! 
It has been exactly 41 years since archaeologist Donald Johanson has unearthed Lucy - a nearly complete skeleton of a female hominid in Ethiopia. Hominids are our ancestors and are nearly the same to homo sapiens today. 
The female skeleton that was unearthed got its name from The Beatles' song, "Lucy in the Sky with Diamonds."
Lucy lived approximately 3 million years ago and her human species had quite small brains, yet they already walked on two legs like us. 
Lucy belonged to the Australopithecus afarensis, which roamed Africa about 4 million years ago. 
Lucy was discovered in 1974, November 24th, so let's all take a round of applause of Lucy- the female skeleton that changed our view of history!
