That’s because since 1955, a growing prevalence of factories and pollution-emitting businesses along the river have made it unsafe for humans. In addition, an increasing number of various bacteria and toxic sediment have, due to its location on the river’s floor, been able to sit, then grow and spread, according to Lawaetz...
...PNAS paper "provides absolutely no evidence that the unique combination of features found in Homo floresiensis are found in any modern human." He argues that the asymmetry in the skull was due not to disease but to the skeleton being buried for thousands of years in 30 feet of sediment, which deformed the fossil. (Thorne insists the deformity must have happened before death.) Henry Gee, a senior editor at Nature who was responsible for overseeing publication of the original Flores article, calls the PNAS paper "very interesting" but argues that it "cherry-picks the evidence" to support the microcephaly theory...
...Homo floresiensis are found in any modern human." Morwood points out that supporting papers have previously been published in elite journals like Science and Nature, while Brown argues that the asymmetry in the skull was due to the fact that the original skeleton was buried in 30 ft. of sediment, which deformed the fossil. (Thorne insists the deformity must have happened before death). Colin Groves, an Australian biological anthropologist who is an author on an upcoming paper in the Journal of Human Evolution that discounts the microcephaly hypothesis, says the PNAS team subtly shaped the evidence to fit their conclusion...
...salt water intrudes deeper and deeper inland, killing vegetation that helps hold the soil together. The elimination of natural flooding also causes barrier islands, which line the Gulf and protect the coast, to shrink. The Mississippi in its naturally flowing state spilled silt into an intricate delta, spreading sediment east and west and fortifying the islands. Walled and dredged all the way to the Gulf, the river now dumps that silt right over the edge of the continental shelf. Geologists report that the Chandeleur Islands--a healthy necklace of sandy barriers about 70 miles from New Orleans--appeared to have...
...hanging like abrupt cries in the air of history. All are tackled by the scholars ... At one end of the room, the fragments are prepared for mounting. Those too brittle to be uncurled are placed in a humidifier ... Then they are cleaned of sand, mold and marl (a clayey sediment) with fine camel's-hair brushes ... Some are so delicate that special brushes of only a few hairs must be used; and these fragments bear warnings?Don't Touch or, occasionally, DON'T BREATHE!" Read more at timearchive.com...
