a case in point

[wangming]

Researchers are finding that in many ways an individual bacterium is more analogous to a component cell of a multicellular organism than it is to a free-living, autonomous organism. Anabaena, a freshwater bacteria, is a case in point.

In this sentence, I cannot clearly understand the "a case in point". Wether the Anabaena is fit for the researchers' finding or not? Some one give me an answer.

"A case in point" means an example which makes clear what you want to express. In this example, yes, the Anabaena is fit for the researcher's finding.
