One of my definitions of Evolution (in the context of debate) is:
“A version of the history of life on Earth in which it is claimed that all biological life that has ever existed came about solely by non-intelligently guided naturalistic processes.”
I think this accurately describes Evolution in the context of the Creation/Evolution debate.

I believe that in science, the working definition is "descent with modification."
“descent with modification” can be vague (even possibly compatible with creationism depending on the situation), and is just one of several evolutionary scenarios, so it’s not a definition that’s comprehensive.
Also, evolutionary theory allows for traits to to be received laterally and not just by descent.
