Two absorption line indices, Ca II and Hδ/λ4045, measured from high-resolution spectra are used with evolutionary synthesis models to verify the presence of a young stellar population in NGC 5018. The derived age of this population is ~2.8 Gyr with a metallicity roughly solar, and it completely dominates the integrated light of the galaxy near 4000 Å.
