Ardipithecus ramidus lived in trees and walked upright

A primate fossil found in Africa in 1994 predates the famous “Lucy” skeleton by 1 million years and offers clues to human evolution, researchers say. “This is huge,” a paleoanthropologist tells the Washington Post. “This is the biggest discovery really since” Lucy. The researchers believe “Ardi”—Ardipithecus ramidus—lived in trees but could walk upright to forage for food on the ground.

“Ardi” would have been able to live in both the forest and savannah environments of Africa some 4 million years ago. “Is she our ancestor?" the team’s leader wonders. “Probably not. If she didn't have any kids, tough luck, she's nobody's ancestor.” But the fossil is as close as scientists have come to the “last common ancestor” of chimps and humans, and suggests our primate cousins have evolved much more than we have.

Ardi tells us twice as much as Lucy did. We have hands and feet, a more complete environment, a more complete skeleton, it's older, it's more primitive, it shows us the process of transformation. - C. Owen Lovejoy, Kent State University
