I do understand the meaning of "if anything" in the context. I can understand each word individually.
Here is the text:
In the past it was a common belief that snakes couldn't hear much, if anything, since they have no external ears and don't seem to respond much to noises. However, some scientific research refutes this common misconception.
I feel like the text is understandable without saying "if anything" so why does the writer put it in the text?
