Galaxies process the raw materials of the universe. Thus, studying the stars in galaxies and their histories gives us an insight into how the universe has changed with time, how galaxies likely formed, and how they will evolve.

It is tempting to assert that the most metal-poor stars in the Galaxy are the direct descendants of the first stars. This is not necessarily the case though, as metal-poor stars form over a range of redshift.
