Lucy
Lucy was found by Donald C. Johanson Ph.D. and Tom Gray on November 30th 1974, in
the Hadar Region in Ethiopia and was named after the song Lucy in the Sky With
Diamonds. She is special because she lived just less than 3.18 million years and because
about 40% of her skeleton was found. Lucy walked on two legs and was about 36 tall
and weighed 60 to 65 Lb..
Lucy was a part of the species Australopithecus afarensis. The species was named
by Donald Johanson and T. White in 1978. The species was eventually accepted by most
researchers as a new species of australopithecine and a likely candidate for a human
ancestor. Lucy is possibly the best known specimen of Australopithecus afarensis.
Australopithecus afarensis is a sexually dimorphic species which means that the males are
bigger than the females this is how we know Lucy was a female. Some of the
characteristics of Australopithecus afarensis is a low forehead, a bony ridge over the eyes,
a flat nose, no
