What do creationist think of the analogy of language to evolution?

There are small changes over time and accelerated in isolated populations. These small changes compound to the point that the segregated population is dramatically and unequivocally distinct from the ancestral population.

So if the creationist can accept and recognize the concept that small, compounded changes result in dramatic, virtually unrecognizable change...what justification do they have to reject this self-evident and proven principle when it comes to evolution?
