Shifting trade Routes May Have Been Root Cause Of Mayan Decline
2012-05-24 10:44:28

Brett Smith for RedOrbit.com The end of the classic Mayan civilization in the lowlands of Mesoamerica was likely expedited by shifting trade routes that started to bring valuable goods to coastal regions instead of the inland city-states of the ancient Native Americans. While the cause of this decline is still shrouded in mystery, most scholars consider the period of the Maya Collapse to be between the 8th and 9th centuries. During this time, the highly sophisticated societies that...

Sophisticated Blade Production Much Earlier Than Originally Thought
2011-10-17 09:21:47

Blade manufacturing "production lines" existed as much as 400,000 years ago, say TAU researchers Archaeology has long associated advanced blade production with the Upper Palaeolithic period, about 30,000-40,000 years ago, linked with the emergence of Homo Sapiens and cultural features such as cave art. Now researchers at Tel Aviv University have uncovered evidence which shows that "modern" blade production was also an element of Amudian industry during the late Lower Paleolithic period,...

HUNTERSVILLE, N.C., April 11, 2011 /PRNewswire/ -- A dull utility blade on the job isn't going to cut it - literally - and it creates frustration, unwanted delays, and loss of productivity for tradesmen. IRWIN® Tools announced today a new 4-Point Snap Blade that snaps on the score to create four cutting points, doubling the number of cuts made by standard carbon blades. Combining the toughness of a traditional utility blade with the versatility of a snap blade, the new...

Stone Age humans were only able to develop relatively advanced tools after their brains evolved a greater capacity for complex thought Stone Age humans were only able to develop relatively advanced tools after their brains evolved a greater capacity for complex thought, according to a new study that investigates why it took early humans almost two million years to move from razor-sharp stones to a hand-held stone axe. Researchers used computer modelling and tiny sensors embedded in...

Was it the evolution of the hand, or of the brain, that enabled prehistoric toolmakers to make the leap from simple flakes of rock to a sophisticated hand axe? A new study finds that the ability to plan complex tasks was key. The research, published today in the Public Library of Science journal PLoS ONE, is the first to use a cyber data glove to precisely measure the hand movements of stone tool making, and compare the results to brain activation. "Making a hand axe appears to require...

Researchers have discovered the oldest evidence to date that prehistoric humans in southern Africa had mastered a complex, delicate process to sharpen stones into spears and knives at least 75,000 years ago, more than 50,000 years earlier than previously believed, according to a study published Thursday. The technique, known as pressure flaking, took place at Blombos Cave in modern day South Africa during the Middle Stone Age by anatomically modern humans, and involved the heating of silcrete...

Chert is a fine-grained silica-rich cryptocrystalline sedimentary rock that may contain small fossils. It varies greatly in color from white to black, but most often manifests as gray, brown, grayish brown and light green to rusty red; its color is an expression of trace elements present in the rock, and both red and green are most often related to traces of iron (in its oxidized and reduced forms respectively). It outcrops as nodules in limestone, chalk, and dolostone formations as a...

Quartz is the second most abundant mineral in the Earth's crust. It has a hexagonal crystal structure made of trigonal crystallized silica (silicon dioxide, SiO2), with a hardness of 7 on the Mohs scale. Density is 2.6 g/cm³. The typical shape is a six-sided prism that ends in six-sided pyramids, although these are often distorted, or so massive that only part of the shape is apparent from a mined specimen. Additionally a bed is a common form, particularly for varieties such as amethyst,...
