    How Man Began

    New evidence shows that early humans left Africa much sooner than once thought. Did Homo sapiens evolve in many places at once?

    By MICHAEL D. LEMONICK

    No single, essential difference separates human beings from other animals -- but that hasn't stopped the phrasemakers from trying to find one. They have described humans as the animals who make tools, or reason, or use fire, or laugh, or any one of a dozen other appealing oversimplifications. Here's one more description for the list, as good as any other: Humans are the animals who wonder, intensely and endlessly, about their origin. Starting with a Neanderthal skeleton unearthed in Germany in 1856, archaeologists and anthropologists have sweated mightily over excavations in Africa, Europe and Asia, trying to find fossil evidence that will answer the most fundamental questions of our existence: When, where and how did the human race arise? Nonscientists are as eager for the answers as the experts, if the constant outpouring of books and documentaries on the subject is any indication. The latest, a three-part Nova show titled In Search of Human Origins, premiered last week.

    Yet despite more than a century of digging, the fossil record remains maddeningly sparse. With so few clues, even a single bone that doesn't fit into the picture can upset everything. Virtually every major discovery has put deep cracks in the conventional wisdom and forced scientists to concoct new theories, amid furious debate.

    Now it appears to be happening once again. Findings announced in the past two weeks are rattling the foundations of anthropology and raising some startling possibilities. Humanity's ancestors may have departed Africa -- the cradle of mankind -- eons earlier than scientists have assumed. Humans may have evolved not just in a single place but in many places around the world. And our own species, Homo sapiens, may be much older than anyone had suspected. If even portions of these claims prove to be true, they will force a major rewrite of the book of human evolution. They will herald fundamental changes in the story of how we came to be who we are.

    The latest shocker comes in the current issue of Nature, where Chinese scientists have contended that the skull of a modern-looking human, found in their country a decade ago, is at least 200,000 years old -- more than twice as old as any Homo sapiens specimen ever found in that part of the world. Moreover, the skull has features resembling those of contemporary Asians. The controversial implication: modern humans may not have evolved just in Africa, as most scientists believe, but may have emerged simultaneously in several regions of the globe.

    Label mistake revealed in oilfish saga

    Indonesia does not export oilfish for human consumption, and is investigating an error made in the translation on the health certificate of fish sold in Hong Kong by the superma

    rket chain ParknShop, according to the Indonesian Consulate in Hong Kong.

    Consul Nugroho Yuwono Aribhimo said Sunday there had apparently been a mistake made in the translation from the scientific name for the fish on the certificate to English.

    "The Latin word [on the certificate] is the name of the oilfish, and the English name is the name of codfish. I don't know what's wrong with the translation between the codfish and the oilfish," he said.

    According to ParknShop, it had labeled fish it offered for sale correctly, according to the name provided on the health certificate issued by Indonesian authorities.

    "There's no Indonesian name for oilfish, and we're still investigating why the translation has become codfish," the consul said.

    The consulate is also investigating the authenticity of the health certificates but said it understood they had been issued by the Indonesian Fisheries Department.

    The consul said the oilfish suppliers are both exporters and importers and officials would investigate.

    He also said oilfish caught in Indonesia is not used for human consumption, and is only exported for use as industrial lubricants to countries like Australia, Canada and Japan.

    He said exports of oilfish to Hong Kong have been halted.

    Meantime, the Food and Environmental Hygiene Department said it has so far received 600 complaints relating to the consumption of oilfish.

    ParknShop said it has already refunded cash to more than 10,000 affected customers, and Wellcome said it has given out refunds to 15 customers so far.

    The controversy erupted last week after the Department of Health's Centre for Food Safety said it had received complaints from 14 people who said they fell ill after eating oil fish wrongly labeled as cod fish bought from ParknShop outlets across the territory.

    The government has ordered a temporary halt to oilfish imports and a curb on sales of the product.

    However, the center said there are no plans to impose a total ban on imports of oilfish whose high oil content is indigestible.
