Google's latest doodle celebrates British archaeologist Mary Leakey

Internet giant Google used on Wednesdat its latest doodle to mark the 100th anniversary of the birth of Mary Leakey, a a British archaeologist and anthropologist, who discovered the first fossilized Proconsul skull.

Mary Leakey discovered the first fossilized Proconsul skull, an extinct ape now believed to be ancestral to humans, and also discovered the robust Zinjanthropus skull. For much of her career she worked together with her husband uncovering the tools and fossils of ancient hominines. She developed a system for classifying the stone tools found at Olduvai.

Google frequently marks important events, anniversaries and birthdays of historic characters from the worlds of cinema, music or science, so this latest doodle is no exception.

However, undoubtedly its most famous doodle to date, and the most tried and tested among Google users, was the one it brought out to celebrate the birthday of the late father of the electric guitar, Les Paul.

On that occasion, Google substituted its usual logo for an electric guitar that allowed the user to play solos with the mouse or the keyboard. It attracted around 740 million users, the equivalent of 10.7 million man hours, according to Australian news.com. Unsurprising perhaps, as many worked out how to play some famous tunes on the doodle.
