A "progenitor" is an ancestor; it means that the quiescent galaxy "plausibly" turns into an elliptical galaxy.

- zuminator 3y agoIn this case precursor might be more precise than ancestor.
- denton-scratch 3y agoAgreed; I knew there was something wrong with "ancestor" when I typed it. [Edit] A progenitor is literally an ancestor; I answered GP's question. It's "progenitor" that should instead be "precursor", in the featured article.
