In 1974 paleoanthropologist Donald Johanson introduced the world to a claimed ancestor of humans which was classified as Australopithecus afarensis or the “southern ape from afar.” The story is that because the song “Lucy in the Star With Diamonds” was playing on the radio at the time of the discovery, the specimen was nicknamed “Lucy.” Lucy is being displayed in museums throughout the world and has had extensive exposure in the United States. The claim is that she is a link giving proof of the evolution of humans from apes. Johanson has a model of human evolution suggesting that apes became erect first, and then their brains developed to make them human. It appears that Lucy’s sacrum and hip might have been arranged in a somewhat vertical position to facilitate erect walking, and Johanson feels that is support for his theory.
The truth is that most of what we know about Lucy and about characteristics that separate humans from apes strongly supports the idea that Lucy was a monkey, and does not support the claims of those who promote naturalism as an explanation of human origins. Here are some of the problems:
1-The brain size of Lucy was about 422 cc. A human’ brain is closer to 1470 cc or more. Chimps’ brains are around 520 cc.
2-Lucy’s mandible (lower jaw) is V-shaped like a monkey’s, not C-shaped like a human’s.
3-Lucy has short, curved toe and finger bones like monkeys. Humans’ are generally straight.
4-Lucy’s humerus (upper arm bone) and femur (upper leg bone) are the same size. A human generally has a 2:1 ratio in size with these bones.
5-Recent studies have shown that Lucy had an exceptionally powerful upper body. This is typical of apes that spend long amounts of time climbing in trees.
6-Lucy’s rib cage was conical (like an ape) while human rib cages are barrel-shaped.
7-Lucy may, in fact, have been a male. The pelvis is heart-shaped and ridge-less which is typical of males.
In the world of anthropology there are lots of new finds being made, but when atheists and skeptics lift a discovery out of context and try to use it as a club against those who believe humans are a special creation of God, the facts get ignored or slanted to whatever model is being promoted.
