Forty years ago yesterday, November 24, 1974, paleoanthropologist Donald Johansson found in Ethiopia what's arguably the most famous and important of a human ancestor: Lucy. Last month, at the ScienceWriters2014 meeting in Columbus, Ohio, Johansson talked about the moment he laid eyes on Lucy. "On that eventful day in 1974 I was out, with a graduate student, Tom Gray, and we were walking back to our Land Rover to go back to camp to enjoy a swim in the river with the crocodiles and enjoy a nice little lunch. And I am always looking at the ground. I find more quarters by parking meters anybody I know, I think. And you know how it is you find what you're looking for, right?" Because a year before the , a geologist had left his footprints four-to-five feet away from the skeleton because he was looking for rocks. I was looking for bones. And I found a little piece of the elbow, that little that allows us to flex and extend our arm. And I knew from my studies of osteology, of comparative anatomy and so on, that this had to be from a human ancestor. "And I as looked up the slope; I saw other fragments out. And we recovered over a two-week-long excavation operation roughly, not counting hand and foot bones, 40 per cent of a skeleton. And this was important because first of all, it broke the three-million-year time barrier. All the fossils older than three million years at that point in the history of palaeoanthropology would fit in the palm of your hand…we didn't know it was a new species really until a few years later when we finally published in 1978 the name Australopithecus afarensis."
