Well, when they got around to making Andromeda, someone was obviously very B7-influenced, as were those making Farscape. A bunch of civilian outlaws on the run... It seems there are two popular templates for starship based SF shows, Trek and B7.
Laypeople think it's "obvious" that any similarity is proof of deliberate imitation, but that's bull. The fact is, accidental similarities happen so routinely that they're a constant source of frustration to writers. We all try to be original, precisely because it's so damn hard to
avoid being unintentionally similar to what someone else has done or is doing. The number one reason why TV story pitches or fiction-magazine submissions are rejected is "We've already bought a very similar story." I encountered that multiple times in just the few occasions when I tried pitching to
Star Trek back in the '90s. When I sent in my first TNG spec script, the episode "Quality of Life" did a similar story just 10 days after I mailed it. One of my DS9 pitches was similar to "Empok Nor," which came along the following year. One or two of my VGR phone pitches got rejected because they were already doing something similar, and when I pitched a reworked-for-VGR version of my DS9 spec script to Joe Menosky, he asked where I got the idea, because it was similar to an original screenplay he'd written.
So you are absolutely wrong to assume that similarity is "obviously" proof of deliberate influence. That is not how it works. Similarities happen by accident all the time. They are very hard to avoid, no matter how hard we try -- and we do try, because nobody wants to be accused of unoriginality. But it's inevitable that different works will happen to have similarities. Because there are only so many concepts out there in the pool of cultural references, only so many plot structures that work, and only so many situations that are identifiable and meaningful to an audience. That's why it's so commonplace for different creators to come up with similar ideas without trying, and why it's so enormously wrong to assume that similarity proves imitation. It's not imitation, it's parallel evolution.
