These unadorned tools remained unchanged for thousands of centuries, until around 1.4 million years ago when Homo ergaster, Homo erectus and other human ancestral groups started doing something new and remarkable. They began shaping single, thin stone blades, sometimes rounded ovals, but often in what to our eyes are arresting symmetrical pointed leaf or teardrop forms. Acheulian hand axes (after St.-Acheul in France, a site of 19th-century finds) have been unearthed in their thousands, scattered across Asia, Europe and Africa, wherever Homo erectus roamed. The sheer numbers of hand axes indicate a rate of manufacture beyond needs for butchering animals. Even more curious, unlike other prehistoric stone tools, hand axes often exhibit no evidence of wear on their delicate blade edges, and some are in any case too big for practical use. They are occasionally hewn from colorful stone materials (even with decoratively embedded fossils). Their symmetry, materials and above all meticulous workmanship makes them quite simply beautiful to our eyes. What were these ancient yet somehow familiar artifacts for? The best available explanation is that they are literally the earliest known works of art — practical tools transformed into captivating aesthetic objects, contemplated both for their elegant shape and virtuoso craftsmanship. Hand axes mark an evolutionary advance in human prehistory, tools attractively fashioned to function as what Darwinians call “fitness signals” — displays like the glorious peacock’s tail, which functions to show peahens the strength and vitality of the males who display it.”&lt;br/&gt;&lt;br/&gt; - &lt;em&gt;&lt;a href="http://www.nytimes.com/2009/10/16/opinion/16dutton.html?pagewanted=1"&gt;Op-Ed Contributor - Has Conceptual Art Jumped the Shark Tank? - NYTimes.com&lt;/a&gt;&lt;/em&gt;</description><link>http://ximenez.tumblr.com/post/214779103</link><guid>http://ximenez.tumblr.com/post/214779103</guid><pubDate>Fri, 16 Oct 2009 13:18:34 -0300</pubDate></item><item><title>Does the Brain Like E-Books? - Room for Debate Blog - NYTimes.com</title><description>&lt;a href="http://roomfordebate.blogs.nytimes.com/2009/10/14/does-the-brain-like-e-books/"&gt;Does the Brain Like E-Books? - Room for Debate Blog - NYTimes.com&lt;/a&gt;</description><link>http://ximenez.tumblr.com/post/213490688</link><guid>http://ximenez.tumblr.com/post/213490688</guid><pubDate>Thu, 15 Oct 2009 01:38:24 -0300</pubDate></item><item><title>Nikon Small World - Gallery - 2nd Place, 2009 - Gerd A.

&lt;p&gt;This is such a good idea that it should be applied to other media as well. Here is my modest proposal to extend three-strikes to the medium of print, that is, to words on paper.&lt;/p&gt;
&lt;p&gt;My proposed system is simplicity itself. The government sets up a registry of accused infringers. Anybody can send a complaint to the registry, asserting that someone is infringing their copyright in the print medium. If the government registry receives three complaints about a person, that person is banned for a year from using print.&lt;/p&gt;</description><link>http://ximenez.tumblr.com/post/107455775</link><guid>http://ximenez.tumblr.com/post/107455775</guid><pubDate>Wed, 13 May 2009 21:59:35 -0300</pubDate></item><item><title>Tute sueña para afuera.
