When it comes to the original migration to the Islands of Southeast Asia (ISEA - namely, the Philippines, Indonesia and Malaysian Borneo), the prevailing theory has been the "out of Taiwan" model - a Neolithic expansion from Taiwan driven by rice agriculture about 4,000 years ago.
Researchers say they have discovered genetic evidence that overturns that theory and takes the timeline back by nearly 10,000 years.
The international research team, led by the UK’s first Professor of Archaeogenetics, Martin Richards, has shown that a substantial fraction of their mitochondrial DNA lineages (…
The human race was divided into two separate groups within Africa for as much as half of its existence, says a Tel Aviv University mathematician. Climate change, reduction in populations and harsh conditions may have caused and maintained the separation.
Dr. Saharon Rosset, from the School of Mathematical Sciences at Tel Aviv University, worked with team leader Doron Behar from the Rambam Medical Center to analyze African DNA. Their goal was to study obscure population patterns from hundreds of thousands of years ago.
Rosset, who crunched numbers and did the essential statistical analysis for…
Ferdinand Magellan set out from Spain in 1519 with hopes of claiming the wealth of the Spice Islands, or Moluccas, for the Spanish. Two years later the explorer claimed the first European contact with a Pacific island culture when he landed on Guam – 1,500 miles north of the Spice Islands.
Was he the worst explorer ever? No, says North Carolina State University archaeologist Dr. Scott Fitzpatrick. Magellan’s historic circumnavigation of the globe was beset by unusual weather conditions, like El Niño, which eased his passage across the Pacific Ocean but sent him over a thousand miles off…
As you read In Praise Of Consumerism - It Appeals To The Thoreau In You you may have wondered if I hated poor Henry David Thoreau. Not at all. He inspired me at the young and impressionable age of sixteen and has powered my engines ever since. There's a good chance that he did the same for you. But brace yourself for irony. Thoreau is the perfect example of the positive aspects of consumerism.
What is consumerism? It’s the flaunting of surplus. It’s the conspicuous display of surplus time, of surplus energy, and of surplus luxuries.
And what was Thoreau doing at Walden Pond? He was…
Complex issues demand complex decision-making and not forced simplification, asserts Lasse Gerrits in his dissertation 'The Gentle Art of Coevolution', and the temptation to make important decisions understandable by simplifying them will eventually turn against the decision maker.
And it is also a myth that complex social issues can be readily resolved as long as there is someone who creates order, he says.
How did he reach his conclusions? He investigated the decision-making concerning the expansion of the Hamburg and Antwerp ports and simplification tends to exacerbate rather reduce…
A team of researchers led by Danish professor Eske Willerslev shows that the ancestors of the North American Indians who came from Asia were the first people in America, and that they were of neither European nor African descent. It also shows that immigration to North America took place approximately 1,000 years earlier than assumed. These findings call for a revision of our understanding of the early immigration route to the American continent.
Willerslev, of the University of Copenhagen, and colleagues recently conducted DNA tests on samples of fossilized human feces found in deep caves in…
An international group of researchers has found evidence for the earliest transport use of the donkey and the early phases of donkey domestication, suggesting the process of domestication may have been slower and less linear than previously thought.
Based on a study of 10 donkey skeletons from three graves dedicated to donkeys in the funerary complex of one of the first Pharaoh's at Abydos, Egypt, the team, led by Fiona Marshall, Ph.D., professor of Anthropology at Washington University in St. Louis, and Stine Rossel of the University of Copenhagen, found that donkeys around 5,000 years ago…
Since the reporting of the so-called “hobbit” fossil from the island of Flores in Indonesia, debate has raged as to whether these remains are of modern humans (Homo sapiens), reduced, for some reason, in stature, or whether they represent a new species, Homo floresiensis.
In a study funded by the National Geographic Society Mission Programs, Lee Berger and colleagues from the University of the Witwatersrand, Rutgers University and Duke University, describe the fossils of small-bodied humans from the Micronesian island of Palau. These people inhabited the island between 1400 and 3000 years…

From Gods To Avicenna
Originating as divine and supernatural, Greek medicine changed and moved toward analysis and logical thinking during the period 800 B.C. to 460 C.E.
Thales (636-546 B.C.), philosopher and scientist, undertakes examination about the laws of nature and physics. He supposed that water (moisture) was the first element from which the world was formed.
Empedocles (Agrigento c.495- c.435 B.C.) philosopher and physician, who lived in Sicily, wrote “On Nature” and “On Purification“. Its system was based on the interaction of the four elements (fire, air, earth and water), called…
Anthropologists from Wheaton College (Illinois) and The Field Museum have discovered how the ancient Maya produced an unusual and widely studied blue pigment that was used in offerings, pottery, murals and other contexts across Mesoamerica from about A.D. 300 to 1500.
First identified in 1931, this blue pigment (known as Maya Blue) has puzzled archaeologists, chemists and material scientists for years because of its unusual chemical stability, composition and persistent color in one of the world’s harshest climates.
The anthropologists solved another old mystery, namely the presence of a 14-…
