U.S. and Ethiopian scientists have discovered fossil remains of what they believe is our first walking ancestor. This find would be the world's
oldest early human skeleton, a hominid that lived in the wooded grasslands of Africa nearly 4 million years ago. The fossilized bones were discovered
in February at a new site called Mille, in the northeastern Afar region of Ethiopia. The fossils include a complete tibia from the lower part of the
leg, parts of a thighbone, ribs, vertebrae, a collarbone, pelvis and a complete shoulder blade. However, the most important fossil in the collection
is an ankle bone which, along with the tibia, proves the creature walked upright on two legs.

ADDIS ABABA, Ethiopia - A team of U.S. and Ethiopian scientists has discovered the fossilized remains of what they believe is humankind's first
walking ancestor, a hominid that lived in the wooded grasslands of the Horn of Africa nearly 4 million years ago.
The bones were discovered in February at a new site called Mille, in the northeastern Afar region of Ethiopia, said Bruce Latimer, director of the
Cleveland Museum of Natural History in Ohio. They are estimated to be 3.8-4 million years old.
The fossils include a complete tibia from the lower part of the leg, parts of a thighbone, ribs, vertebrae, a collarbone, pelvis and a complete
shoulder blade, or scapula. There also is an ankle bone which, with the tibia, proves the creature walked upright, said Latimer, co-leader of the team
that discovered the fossils.
The bones are the latest in a growing collection of early human fragments that help explain the evolutionary history of man.
"Right now we can say this is the world's oldest bipedal (an animal walking on two feet) and what makes this significant is because what makes us
human is walking upright," Latimer said. "This new discovery will give us a picture of how walking upright occurred."

The specimen is the only the fourth partial skeleton ever to be discovered that is older than 3 million years. It was found after two months of
excavation at Mille, 37 miles from the famous Lucy discovery. The bones are the latest in a growing collection of early human fragments that help
explain the evolutionary history of man. "It is a once in a lifetime find," says one of the researchers. Yes, that's an understatement.
Scientists are yet to classify the new find, which they believe falls between A. ramidus and A. afarensis, the 3.2 million-year-old species widely
known by the nearly complete "Lucy" fossil, which measures about 4 feet tall. I wonder how this discovery will change our ancestral "family tree."
It seems that paleontologists are finding new hominid species more and more frequently. Who knows what other fossil remains are waiting to be
discovered.
