Throughout evolutionary history, we never saw anything like a montage. So why do we hardly notice the cuts in movies?

Jeffrey M. Zacks in Aeon:

You might find that odd, no? Now suppose that not just the dog changed, but the sofa too. Suppose everything in your visual field changed instantaneously in front of your eyes.

Imagine further that you were in a crowd and exactly the same thing was happening to everyone around you, at exactly the same time. Wouldn’t that be disturbing? Kafkaesque? In 1895 in Paris, exactly this started happening – first to a few dozen people, then to hundreds and then thousands. Like many fin-de-siècle trends, it jumped quickly from Europe to the United States. By 1903, it was happening to millions of people all over the world. What was going on? An epidemic of an obscure neurological disorder? Poisoning? Witchcraft?

Not quite, though it was definitely something unnatural. Movies are, for the most part, made up of short runs of continuous action, calledshots, spliced together with cuts. With a cut, a filmmaker can instantaneously replace most of what is available in your visual field with completely different stuff. This is something that never happened in the 3.5 billion years or so that it took our visual systems to develop. You might think, then, that cutting might cause something of a disturbance when it first appeared. And yet nothing in contemporary reports suggests that it did.
