One of the earliest known hominids, a 4.4-million-year-old partial skeleton of a female dubbed Ardi, had hands suited for climbing trees and swinging from branches, a new investigation suggests.
These results, based on statistical comparisons of hand bones from fossil hominids and present-day primates, stoke an ongoing debate not only about how Ardi moved (

“The last common ancestor of humans and chimpanzees was more similar to chimps than to any other living primate,” says paleoanthropologist Thomas Prang of Texas A&M University in College Station. That ancestor, who lived roughly 7 million years ago, had hands designed much like those of tree-adept, knuckle-walking chimps and bonobos, he and his colleagues say. That hand design was retained by early hominids such as Ardi’s East African species,
Among the riot of species that have lived on Earth over the last four billion years, only we can ponder our own origins and it often angers the blood. We’re long past any serious debate that humanity evolved from apes in Africa a few million years ago, but the scientists looking for ever older bones of our ancestors always seem to be squabbling.

Origins of Humankind, the journalist Kermit Pattison concurs in his riveting account of the discovery of Ardipithecus, a sometimes climbing, sometimes walking proto-human that lived 4.4 million years ago in Ethiopia. “In an ideal world, the task should be left to more dispassionate investigators but, since no other species has volunteered, the job is left to us imperfect humans,” he writes.
