This contradicts the open savanna theory for the origin of bipedalism, which states that humans learned to walk upright as climates became drier and environments became more open and early ancestors—but we keep learning more! D., Asfaw, B., Beyene, Y., Hailie-Selassie, Y., Lovejoy, C. A partial skeleton of a female, known as "Ardi", combines human and other primate traits.
Paleoanthropologists are constantly in the field, excavating new areas with groundbreaking technology, and continually filling in some of the gaps about our understanding of human reveals the postcrania of our last common ancestors with African apes. Ardi moved in the trees using a grasping big toe, yet her pelvis was shorter and broader than an ape's, indicating that she could walk bipedally.
Ardi instead shows an unexpected mix of advanced characteristics and of primitive traits seen in much older apes that were unlike chimps or gorillas (interactive: Ardi's key features).
As such, the skeleton offers a window on what the last common ancestor of humans and living apes might have been like.

Isotopic chemical analyses of Neanderthal bones also tell scientists the average Neanderthal’s diet consisted of a lot of meat.Announced at joint press conferences in Washington, D.C., and Addis Ababa, Ethiopia, the analysis of the Ardipithecus ramidus bones will be published in a collection of papers tomorrow in a special edition of the journal Science, along with an avalanche of supporting materials published online.You want to pick a name that truly represents who you are and the kind of person you are looking to meet.Dating expert, I recommend choosing an actual word rather than initials or letters.

"This find is far more important than Lucy," said Alan Walker, a paleontologist from Pennsylvania State University who was not part of the research.
