Is there some way to understand the amount of Dark Matter in these galaxies (and whether or not that may be constant or changing over time)?

You can't watch a single galaxy evolve as they evolve over billions of years. Instead you look for galaxies at different stages in their evolution and piece them together.
They are able to measure the mass of the galaxy and compare that to the mass they can see to figure out how much is dark matter.

I am also curious about this. My personal theory about this, is that the dark matter is beyond the limits of the observable universe. I'm not a scientist, but I have studied science my entire life. I can never seem to learn enough to ever be satisfied.
