SUMMARY:Galaxy Evolution from Large Surveys of Nearby Resolved Galaxie
 s\, Astronomy Colloquium\, Karen Masters\, Haverford College
DESCRIPTION:The morphology of a galaxy provides information on the orb
 its of stars within it. As such\, important clues to the formation his
 tory of galaxies are revealed by their morphologies\, and this informa
 tion is complimentary\, but not identical to\, their star formation hi
 story and chemical composition as revealed by photometry and spectra.T
 he Galaxy Zoo project (www.galaxyzoo.org) has provided quantitative vi
 sual morphologies for over a million galaxies (including the entire Sl
 oan Digital Sky Surveys\, or SDSS Main Galaxy Sample)\, and has been p
 art of a reinvigoration of interest in the morphologies of galaxies an
 d what they reveal about the evolution of galaxies.  
\n 
\n
\n Mappin
 g Nearby Galaxies at Apache Point Observatory (MaNGA\, part of SDSS-IV
 )\, has now completed its goal to obtain spatially resolved spectral m
 aps for 10\,010 nearby galaxies (all of which have Galaxy Zoo morpholo
 gies). This is by far the largest sample of resolved spectroscopy in t
 he world. 
\n
\n 
\n
\nIn this talk I will review these  projects\, an
 d show results from them which demonstrate why a resolved view of the 
 internal morphology in large samples of galaxies is interesting and ho
 w it provides a unique constraint of our understanding of galaxy evolu
 tion.
