Google has created one of its trademark doodles to celebrate the 41st anniversary of the discovery of the skeletal remains of the 'Lucy' Australopithecus, who is proven to have lived around 3.2 million years ago in Ethiopia
Perhaps the world's most famous early human ancestor, the 3.2-million-year-old ape "Lucy" was the first Australopithecus afarensis skeleton ever found, though her remains are only about 40 percent complete.40 per cent of Lucy's fossilized remains were discovered intact and paleoanthropologist Donald Johansson named her Lucy after the Beatles song 'Lucy in the Sky with Diamonds'.By studying her bones, in particular the structure of her knee and spine curvature, scientists discovered that she spent most of her time walking on two legs.Lucy resembled human beings very closely. She walked in an upright manner as humans do.
What did Lucy look like?
With a mixture of ape and human features—including long dangling arms but pelvic, spine, foot, and leg bones suited to walking upright—slender Lucy stood three and a half feet (107 centimeters) tall.
Recreations based on other A. afarensis skulls later found nearby reveal an apelike head with a low and heavy forehead, widely curving cheekbones, and a jutting jaw—as well as a brain about the size of a chimpanzee's.
Scientists believe Lucy was 3.7 feet tall and 29kgs in weight.Although she walked upright, she was quite small in size compared to humans. Her skeletal remains are kept in a National Museum in Ethiopia's Addis Ababa and her plastic replica is kept in the public for tourists to observe.
Why was Lucy named Lucy?
Inspired by repeated playings of "Lucy in the Sky With Diamonds" at a celebratory party on the day the specimen was found, researchers gave it the Beatles' mod moniker.
George Boole: Google Doodle celebrates 200th birthday of mathematician dubbed 'father of the information age'Despite having little formal education Boole became a renowned mathematician, logician and philosopher and his work served as the basis for modern computer science.He is known as the mathematician who paved the way for the digital revolution and Google have celebrated what would be the 200th birthday of George Boole with one of their trademark doodles.Boole is known as the "Father of the information age" because of his contributions to modern computer science through his invention of Boolean algebra.Google's animated Doodle is a demonstration of the 'Logic Gates' used in computing that are derived from Boolean functions.Boole died in County Cork, Ireland, in 1864 aged just49 of pneumonia after he walked for two miles in the rain and then gave a lectured while in his wet clothes.
