It means to roll or unroll. The car Volvo is a play on this latin word as well.
Evolution is a step wise continuum. It is rolling or unrolling as it were. Questions of the origin of molecules associated with life are part of this same evolutionary continuum.
The root word is irrelevant. Biological evolution is not an unrolling. The word was in use long before Darwin and long before the modern synthesis was reached.
Why is "unrolling" significant to you?
"I am referring to the root for the word evolve.
It means to roll or unroll."
Evolution is actually an unfortunate term for the process. Darwin used the term *transmutation*, which is more accurate.
That being said, the roots of the word are irrelevant because the meaning of the word has changed. In biology evolution is not used as *unrolling*.
