We observe a continuous increase in C/O with increasing O/H over the range -4.7 < log(O/H) < -3.6. One interpretation is that the most metal-poor galaxies are the youngest and dominated by the products of early enrichment by massive stars, while more metal-rich galaxies show increasing, delayed contributions of C from intermediate mass stars. However, recent evolution models for massive stars including mass loss suggest that the ","authors_text":"D. R. Garnett, E. D. Skillman, E.Terlevich, G. A. Shields, M. Peimbert, R. J. Dufour, R. J.
