Comparisons among stellar birthrate figures for stars of 05-9 and B0, 0.5 and 1 spectral type show that the current rate of nucleosynthesis is compatible with the idea of massive stars producing most of the metals only in the event that the stellar birthrate decreased with time. The current stellar evolution data, as well as observations, do not support the premise that intermediate mass stars are the source of the bulk of the nucleosynthesis in the galaxy. It is concluded that the limits of the Simple Model must be surpassed with the supposition of prompt initial enrichment, in order foo the stellar birthrate to be constant while the metals originate in the massive stars.
