据美国《科学》杂志报道，考古学家在南非发现了可能是目前已知的最古老的艺术作品，其年代至少比在欧洲的山洞中发现的最早的壁画提前了４万年。一些研究人员由此认为，这项在一个名为Blombos的洞穴中的新发现，非常有力地证明了现代人类行为被唤起的时间要比通常所认为的年代 According to a report in the U.S. Science, archaeologists discovered the oldest known art work in South Africa that may be known at the time, at least 40,000 years earlier than the earliest murals found in caves in Europe. Some researchers, therefore, believe that this new discovery in a cave called Blombos strongly demonstrates that modern human behavior is evoked more than is generally assumed
