Okay, so I asked this question about the plausibility of large hexapods on Worldbuilding Stack Exchange. Although it wasn't closed, several people pointed out that I was asking about too many things at one time. Therefore, I am thinking about splitting it into several smaller questions, each asking about one of the aspects of the topic.
However, I am unsure about the exact format this should be in. I think the general problem of splitting a broad question that has already been asked is relevant across many subjects, which is why I am asking for an answer here. I also know that it is generally advised that one question should be asked at a time, but my problem is that the broad question has already been written and posted. So, I am wondering - should I delete the original question and start completely afresh, or should I link to the original question in my new questions?
