Technological evolution is the name of a science and technology studies theory describing technology development, developed by Czech philosopher Radovan Richta. According to Richta and later Bloomfield, technology (which Richta defines as "a material entity created by the application of mental and physical effort to nature in order to achieve some value") evolves in three stages: tools, machine, automation. This evolution, he says, follows two trends: the replacement of physical labour with more efficient mental labour, and the resulting greater degree of control over one's natural environment, including an ability to transform raw materials into ever more complex and pliable products.
