Common Ancestors is going to muddy the conversation with the prospect of various different common ancestors spread out across space and time.
Most Recent Common Ancestral Population would be more accurate, but hitting a n00b with MRCAP and trying to explain speciation as the gradual divergence of subpopulations over both space and time is going to be a bit overwhelming. Simplification is a necessary pedagogical tool or you'd need a course in optics to properly understand why rainbows happen. Add a course in child psychology and a degree in education plus a few weeks of time to explain that to your average 4 year old.
