Answer:
By watching artists today we can have a pretty good idea of how long it would have taken to draw or paint the pictures we find inside caves. That time is generally far beyond the time that a burning branch, for instance, will give light. The development of artificial lighting has been one of the most important, but slowest, of technological developments. It is worth appreciating that the evolution of art not only relies on advances in technology, it has also been the major source of much of our information about the evolution of other technologies. Digital art, laser and inkjet printing, 3D printing, and other technologies continue the co-evolution of art and technology.
