• Social change happens by 3 processes: & is based largely on technology 1) Invention – combining of existing elements and materials to form new ones
I died in 1959
2) Discovery – a new way of seeing reality 3) Diffusion – the spread of invention or discovery from one area to another can have extensive effects on people’s lives. (e.g. Columbus and rats / disease or Missionaries introducing axes to Australian Aborigines)
• Cultural lag – some elements of a culture lag behind the changes that come from invention, discovery, and diffusion 1 4
