Liesegang rings are a phenomenon of periodic precipitation resulting in circular patterns that impressed scientists a lot a while ago, to the point it came out not only as a physico-chemical process, but as an explanation for some biological phenomena as well. As far as I can tell read, no unifying grand theory of this Liesegang phenomenon made it completely yet, chemically speaking. The thing is, with regard to biology, it did not really stand as a process of any explanatory power, and it disapeared from the biological jargon.

It’s amazing to see that, though people tried to look into microbiomes and microbionts, we are still not knowing much about all of this.
