  We report on a new study aimed at understanding the diversity and
evolutionary properties of distant galactic bulges in the context of
well-established trends for pure spheroidal galaxies. Bulges have been isolated
for a sample of 137 spiral galaxies in the GOODS fields within the redshift
range 0.1 < z < 1.2. Using proven photometric techniques we determine for each
galaxy the characteristic parameters (size, surface brightness, profile shape)
in the 4 GOODS-ACS imaging bands of both the disk and bulge components. Using
the DEIMOS spectrograph on Keck, precision stellar velocity dispersions were
secured for a sizeable fraction of the bulges. This has enabled us to compare
the Fundamental Plane of our distant bulges with that of field spheroidal
galaxies in a similar redshift range. Bulges in spiral galaxies with a
bulge-to-total luminosity ratio (B/T) > 0.2 show very similar patterns of
evolution to those seen for low luminosity spheroidals. To first order, their
recent mass assembly histories are equivalent.
