From ScienceDaily:

Rich array of artifacts shows mix of techniques dating to early Upper Paleolithic

The rich array of artifacts shows a mix of techniques for making points, blades, scrapers and cutting flakes. “These toolmakers appear to have achieved a division of labor that may have been part of an emerging pattern of more organized social structures,” Stutz says.

The theory that greater social division of labor was important at this prehistoric juncture was first put forward by anthropologists Steven Kuhn and Mary Stiner.

“Our work really seems to support that idea,” Stutz says. “The finds from Mughr el-Hamamah give us a new window onto a transitional time, on the cusp of modern human cultural behaviors, bridging the Middle and Upper Paleolithic.”More.

As with the claim that the Neanderthals didn’t know how to kill rabbits (and that is one reason they died out), claims like this are most interesting but vulnerable to new discoveries.

What if an older tool shop were found? Then this one isn’t the dawn any more. It could be mid morning.

OT: Newfound groups of bacteria are mixing up the tree of life - June, 15, 2015 University of California, Berkeley, scientists have identified more than 35 new groups of bacteria, The new groups make up more than 15 percent of all known groups or phyla of bacteria, the scientists say, and include the smallest life forms on Earth, microbes a mere 400 nanometers across. The number of new bacterial phyla is equal to all the known animal phyla on Earth.,,, the accepted tree of life - a division into the three domains of eukaryotes, which includes animals and plants, bacteria and Archaea - needs to be revised.,,, About half of all the genes in these 35-plus phyla are new and unlike other known genes. The recognizable genes suggest that most of the bacteria use a simple process of fermentation to make the energy they need, instead of using aerobic or anaerobic respiration like many other bacteria. They also have unusual ribosomes, the multi-protein machines that translate genetic instructions into proteins. In fact, routine genomic scans would not detect them because of their distinctive 16S ribosomal RNA genes.,,, http://phys.org/news/2015-06-newfound-groups-bacteria-tree-life.htmlbornagain77

OT: Podcast - The God Solution – Pt 1 - June 15, 2015 On this first episode of ID the Future, Nate Herbst of The God Solution and Casey Luskin discuss their experiences as students, interacting with professors over the origins of life controversy. Luskin describes how involvement in a student club first awakened his interested in the intelligent design debate. http://www.discovery.org/multimedia/audio/2015/06/the-god-solution-pt-1/#more-28841bornagain77
