Hmmm, I might suggest hieroglyphics is less susceptible to change than English. For one thing, it is not a every-day language, so it need not change with the evolving vocabulary needs of its society. So It's more like Latin than English in this sense. For another, it's style is independent of how it is pronounced, so it need not change with the evolving pronounciation of a spoken language. So it's more like Chinese than English in this sense.
So I might say the developmental properties of Hieroglyphics is more comparable to archaic written Chinese than any modern language.
