Philosopher Michael L. Peterson explains junk DNA for us at BioLogos in “Evolution and the Deep Resonances between Science and Theology, Part 5” (July 20, 2011):
Evolution is the only rational way to account for the molecular uniformity of all organisms, given that numerous alternative structures and fundamental processes are, in principle, equally likely. Moreover, the accumulation of damaged or “junk” DNA (mutations that do not affect function and thus are not subject to negative selection), passed on over time to species further down that branch of the Tree, makes the probability that evolution did not occur infinitesimally small.
