Is there evidence for a common ancestor between the Discovery's Tardigrade and Voyager's Nacene?

Question

In the Star Trek Discovery Episode S1:E3 Context is For Kings - we see the Tardigrade - part of what enables the USS Discovery's Spore Drive (at the time).

The reason the Discovery harnesses the Tardigrade is its ability to travel along the mycelial plane, and thus transport the ship at faster than warp speeds.

In the Star Trek Voyager Episode S2:E10 Cold Fire we see the Nacene - a sporocystian lifeform with high-level technology and an apparently natural ability to navigate subspace.

Now these two creatures appear to have similar, but not identical characteristics. Keeping in mind the Nacene appears to have better than human intelligence, whereas they were only just confident the Tardigrade was intelligent at all. They're both aliens that can travel at faster than Warp speeds and survive in the expanse of space. (They also both have a blue-glow).

Indeed, the following commentator writes:

Is there a relationship between the Tardigrade and the sporocystian life form from Voyager?

My question is: Is there evidence for a common ancestor between the Discovery's Tardigrade and Voyager's Nacene?

Answer 1

At this point in time, it appears that there is no direct evidence (as in, basically nothing beyond the suggestive similarities given in the question) of any connection between the two life forms. Of course, that may well change as the Tardigrade's nature is explored more in Discovery and other works.
