Is it generally true that the further away a galaxy is (and more red-shifted), the more it tends to contain lower metal content stars? I'd always assumed this was one of the main bits of evidence for the Big Bang, but I've also read that the globular clusters that surround (and are gravitationally bound to) large galaxies such as our own contain mostly "old" (primitive, 2nd generation?) stars. (I realize that these facts are not necessarily contradictory, but I'd like to know what the astronomy community thinks about it.)
