人类的躯体有着其遗传的生物力学,这一点决定了人类和自然环境相互作用的本质。由于如此及其二足特征,人类以不同于黑猩猩的方式投掷石块。其平衡力有异于较高级的灵长目。作为这种生物力学的结果,尽管人们的文化遗产不同,但世界各地的接合、操纵、创作及均衡物质和装备的最基本的品质却是类似的。这些品质也许几百万年前就开始发展了,确切地将人类 The human body has its own genetic biomechanics, which determines the nature of the interaction between humans and the natural environment. Because of this and its two-legged characteristics, humans throw stones in ways other than chimpanzees. Its balance is different from the higher primates. As a result of this biomechanics, despite the differences in cultural heritage, the most basic qualities of engagement, manipulation, creation and equalization of material and equipment are similar across the world. These qualities may have started to develop millions of years ago, exactly human
