Morphology

common + progenitor

The meaning is directly compositional: 'common' (shared) + 'progenitor' (ancestor) yields 'a shared ancestor,' so the sense is transparently derivable from the parts. This combination follows a straightforward adjectival + noun pattern found across languages (e.g., 'common ancestor'), making it readily interpretable by a B1 learner who knows the constituent words.

Etymology

The noun common progenitor gives a simple image: progenitor is the first parent at the base of a family tree, and common shows that several branches come from that same one. So it means 'a shared ancestor' or 'original source' of different groups.
