Fossil Find Shakes Up Evolution Timeline

Ardipithecus ramidus lived in trees and walked upright

Share

(Newser) – 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

The Ardipithecus genus gave rise to Australiopithecus even though we can't say exactly what species did. Maybe ramidus did. But certainly something like ramidus did. - Tim White, UC-Berkeley

Fascinating! I just picked up Richard Dawkins' book The Greatest Show On Earth, so I'm diving into this subject right now. Reply

There is no missing link. Evolution is an unproven theory. This is find #1001 that is supposed to be the silver bullet of evolution. It is further atheist bullshit.

@krystle.... if you love angry hateful writing, you'll love Dawkin's book. There's not much factual information in it, but it's full of hatred of others who disagree with Dawkins.... right up your liberal alley I'm sure.

Dawkins is great stuff. He's a bit abrasive at times, but rightfully so! People that have no idea what they are talking about are constantly trying to drag is work through the mud. It's like working in advertising.
