Change is a perfectly good word for change.
Evolution is about explaining some mighty huge differences between species as "change," rather than saying they are different as part of a creator's plan to make different species. Evolution is about denying the existance of a creator, a designer, a planner or a plan... and boiling every life form back down to the happenstance primordial soup from whence we came.
That's why chicken soup is so good for you when you're sick.
