Little Lucy

Talking about theories that have to change to accomodate new information:
The remains of the earliest known child from humanity’s family tree have been discovered in Ethiopia, in an unprecedented find that fills in a critical missing link in human evolution.

The almost complete skeleton belongs to a baby girl of the species Australopithecus afarensis — a probable human ancestor that was among the first to walk on two legs — who died at the age of three about 3.3 million years ago.

...Early analysis of Selam [The name given the fossil - it means "peace" - C] has already started to transform understanding of a pivotal stage in the evolutionary process that led ultimately to Homo sapiens. Her anatomical features lie squarely in between those of humans and other apes, showing adaptations both for walking upright on two legs and for climbing and swinging from trees.

This suggests that the species lived on the cusp of the human family’s transition to a bipedal, ground-based existence, which is generally accepted as one of the most crucial events in the emergence of the modern anatomy.

Selam’s brain case also suggests that while her intellect was more similar to a chimp’s than a person’s, her species’s brain had already started to evolve in the direction that would produce modern human intelligence. Details of the fossil are published today in the journal Nature.
The Creative Design folks are always talking about how evolution is bunkum because there are gaps in the fossil records...missing links. Then again, they also claim the Earth is only a few thousand years old.
