...theme, begins in the mid-19th century with the awkwardness of photography's initial undertakings. The original challenge posed to photography was how a mechanical and scientific medium could function as a forum for creativity. Photographers responded by subverting the mechanical nature of the medium and imitating its paternal ancestor of painting...
Until this year the famed Lucy and her fellow members of the species Australopithecus afarensis were the oldest known members of the human family. No more: at 4.4 million years of age, the newly unearthed Australopithecus ramidus is the closest link yet (no longer missing) to the common ancestor of apes and humans. A second major find: Homo erectus, the first of Lucy's descendants to leave Africa, made that move about 800,000 years earlier than had been thought. Anyone want an obsolete paleontology book, cheap...
...discovered about 50 miles north of the current find. That 3.2 million-year-old female hominid had some human characteristics -- most notably, she walked on two legs rather than four -- but skull and tooth fragments indicated she was somewhat apelike as well. She fit nicely into the shared-ancestor theory first put forward by Charles Darwin and supported by modern comparisons between human and ape proteins and DNA. The divergence between the ape and human lines, argued the biochemists, came somewhere between 4 million and 6 million years ago. And some paleontologists predicted that as hominid species were discovered from...
...current , Nature that the archaic molar, along with other fossils they found in the area on expeditions in 1992 and 1993, belong to a previously unknown species. This diminutive, humanlike creature walked the earth some 4.4 million years ago -- half a million years earlier than the oldest human ancestors ever identified. That stretches our family tree back almost to the era when humans and apes branched off from a single ancestor. In fact, says University of Liverpool paleontologist Bernard Wood, whose commentary on the find also appears in Nature: "It looks to me like this is either the common ancestor...
...afarensis, ramidus had teeth with some apelike and some human characteristics. But at least one specimen -- a baby molar still attached to a piece of an immature ramidus jaw -- resembles a chimpanzee tooth more than a molar from any known hominid. "It's obvious that it belongs to an ancestor of afarensis," says Tim White of the University of California, Berkeley, a co-author of the Nature report and a leader of the international team that uncovered the new fossils...
