Egyptian Carvings Among World's Oldest

Scientists have dated rock carvings found in Qurta, Egypt, to be between 15,000 and 23,000 years ago, making them the oldest Egyptian works of art known to exist and among the oldest art found anywhere.
These carvings offer views of animals that the Paleolithic hunters encountered ~ mostly the wild predecessors of the domestic cattle of today. Other carvings, called petroglyphs, depict hippos and gazelles. Humans are found, too, among the drawings, but usually they are shown only as stick figures.
The researchers said that the carvings have more in common with the drawings found in Lascaux, the cave in France, as opposed to the art of the Egyptian dynasties. The Lascaux cave paintings have been dated to 17,300 years ago, or about the same era as this new discovery in Egypt.
"As such, they're not considered as Egyptian art, because it predates the appearance of Egyptian culture," said Yale's Colleen Manassa, assistant professor of Egyptology. She added that it even pre-dates "by a long shot" the predynastic art that was the precursor to Egyptian art.

Homo Sapiens' Journey to Modern Human


Scholarly debate surrounds when “archaic Homo sapiens” emerged as the modern version of humans. American Scientist recently explored the topic in an article, “Refuting a Myth About Human Origins” by John J. Shea, professor of anthropology at Stony Brook University and a research associate with the Turkana Basin Institute in Kenya.
In Europe, the oldest Homo sapiens fossils date to only 35,000 years ago. But studies of genetic variation among living humans suggest that our species emerged in Africa as long as 200,000 years ago. Scientists have recovered Homo sapiens fossils in contexts dating to 165,000 to 195,000 years ago in Ethiopia’s Lower Omo Valley and Middle Awash Valley. Evidence is clear that early humans dispersed out of Africa to southern Asia before 40,000 years ago. Similar modern-looking human fossils found in the Skhul and Qafzeh caves in Israel date to 80,000 to 120,000 years ago. Homo sapiens fossils dating to 100,000 years ago have been recovered from Zhiren Cave in China. In Australia, evidence for a human presence dates to at least 42,000 years ago. Nothing like a human revolution precedes Homo sapiens’ first appearances in any of these regions. And all these Homo sapiens fossils were found with either Lower or Middle Paleolithic stone tool industries.
Shea delineates the various findings and frequently references his own take on the situation, as in:
For me, the most surprising aspect about the debate regarding when Homo sapiens became human is that archaeologists have not tested the core hypothesis that there were significant behavioral differences between the earliest and more recent members of our species. Because modernity is a typological category, it is not easy to test this hypothesis. One is either behaviorally modern or not. And, not all groups classified as behaviorally modern have left clear and unambiguous evidence for that modernity at all times and in all contexts. For example, expedient and opportunistic flintknapping of river pebbles and cobbles by living humans often creates stone tools indistinguishable from the pebble tools knapped by Homo habilis or Homo erectus. This similarity reflects the nature of the tool-making strategies, techniques and raw materials, not the evolutionary equivalence of the toolmakers. Thus, the archaeological record abounds in possibilities of false-negative findings about prehistoric human behavioral modernity.

Breadmaking Goes Back 30,000 Years

Starch grains found on 30,000-year-old grinding stones indicate prehistoric man ate an early form of flat bread, contrary to his popular image as primarily a meat-eater. The new findings show that Palaeolithic people ground plant roots similar to potatoes to make flour, which was then made into dough.

"It's like a flat bread, like a pancake with just water and flour," Laura Longo of the Italian Institute of Prehistory and Early History told Reuters News. "You make a kind of pita and cook it on the hot stone."

The result was "crispy like a cracker but not very tasty," she added.

The grinding stones ~ each of which fit comfortably into an adult's palm ~ were discovered at archaeological sites in Italy, Russia and the Czech Republic. Researchers said their findings throw mankind's first known use of flour farther back some 10,000 years. The previously oldest evidence had been found in Israel on 20,000 year-old grinding stones.

The findings may also upset fans of the Paleolithic diet, which follows earlier research that assumes early humans ate a meat-centered diet.
