earliest undisputed art originated with the Homo sapiens Aurignacian archaeological culture in the Upper Paleolithic. However, there is some evidence that the preference for the aesthetic emerged in the Middle Paleolithic, from 100,000 to 50,000 years ago. Some archaeologists have interpreted certain Middle Paleolithic artifacts as early examples of artistic expression. The symmetry of artifacts, evidence of attention to the detail of tool shape, has led some investigators to conceive of Acheulean hand axes and especially laurel points as having been produced with a degree of artistic expression. Similarly, a zigzag engraving supposedly made with a shark tooth on a freshwater Pseudodon shell DUB1006-fL around 500,000 years ago (i.e. well into the Lower Paleolithic), associated with Homo erectus, could be the earliest evidence of artistic activity, but the actual intent behind this geometric ornament is not known. There are other claims of Middle Paleolithic sculpture, dubbed the "Venus of Tan-Tan" (before 300 kya) and the "Venus of Berekhat Ram" (250 kya). In 2002 in Blombos cave, situated in South Africa, stones were discovered engraved with grid or cross-hatch patterns, dated to some 70,000 years ago. This suggested to some researchers that early Homo sapiens were capable of abstraction and production of abstract art or symbolic art. Several archaeologists including Richard Klein are hesitant to accept the Blombos caves as the first example of actual art. In September 2018 the discovery in South Africa of the earliest known drawing by Homo sapiens was announced, which is estimated to be 73,000 years old, much earlier than the 43,000 years old artifacts understood to be the earliest known modern human drawings found previously. The drawing shows a crosshatched pattern made up of nine fine lines. The sudden termination of all of the lines on the fragment edges indicate that the pattern originally extended over a larger surface. It is also estimated that the pattern was most likely more complex and structured in its entirety than shown on the discovered area. Initially, when this drawing was found, there was much debate. To prove that this drawing was created by Homo Sapiens, French team members who specialized in chemical analysis of pigments, reproduced the same lines using a variety of techniques. They concluded that the lines making up the drawing were intentional and were most likely made with ocher. This discovery adds further dimensions to understanding the behavior and cognition of early homo sapiens. Neanderthals
