Where is your counterexample, especially a counterexample from a time before when photography was invented, which is what I would expect to see a link to after a statement like that? For you and for anyone else who would like to read a really deep, interesting book about how visual art has developed over the history of humankind (and about many other issues), I recommend The Nature of Paleolithic Art[1] by R. Dale Guthrie, a book I enjoyed reading several years ago. Guthrie is a field biologist and very competent visual artist who specializes in Pleistocene megafauna like mammoths. He went to most of the oldest sites of surviving cave art and personally looked at ancient drawings on site as he studied examples of early art for his book. He devotes pages of thoughtful discussion to what early human drawings show and what drawing problems early artists encountered. He specifically mentions the problem of drawing running human beings and running four-legged animals.
