Using spectroscopic data from the Deep Extragalactic Evolutionary Probe (DEEP) Groth Strip survey (DGSS), we analyze the gas-phase oxygen abundances in the warm ionized medium for 64 emission-line field galaxies in the redshift range 0.26-19) end of the sample and vanishingly small for objects at the high-luminosity end of the sample (M_B ~ -22). Simple galaxy evolution models can produce reasonable agreement with observations for low-mass galaxies when least two of the following are true: 1) low-mass galaxies have lower effective chemical yields than massive galaxies, 2) low-mass galaxies assemble on longer timescales than massive galaxies, 3) low-mass galaxies began the assembly process at a later epoch than massive galaxies.
