Art

Couple of stream of consciousness ideas that just came up. The phenomenon of surfing the web, copying and pasting links and emailing them to people is wholly contingent on the modern era. The only thing close to a historical analogy would be sitting in a library going through books, documents, encyclopedias and albums, writing down the articles or tracing the illustrations then putting them in an envelope and mailing it to a friend. And that's not including multiple recipients or forwarding YouTube videos.
Also, flowering plants only started appearing around the time of the dinosaurs. Imagine if that little evolutionary experiment hadn't worked out. How many foods, concepts or metaphors would no longer exist? Just on the poetic/aesthetic aspect, how would civilization have coped? What would Van Gogh have painted? Roses wouldn't be red, violets wouldn't be blue, there would be no sugar to be sweet and you know the rest.
And how would aliens with no sight organs create art? Would it all have to be tactile? That limits them to portraits and still lifes since they wouldn't be able to create a recognizable representation of a landscape. Would they regard paintings as some kind of abstract form of koan? Like maybe the way the paint is situated on the canvas is symbolic of the place where it was painted or a general pattern of paint represents a cloud. They'd sense the paint but couldn't understand how it represents a landscape. That said, they may very well have some other form of long range sense we do not comprehend and have developed art based around that sense. What, then, would we make of that?
