Ok Mr. Scientist, give us the exact scientific definition of evolution.

Which broad definition would you like, any definition that I give will necessarily be argued by some, as you call them "evolutionists", to be incomplete. A full definition would take quite a bit of space so I will keep it as succinct as I can.
Biological evolution: Biological evolution ... is change in the properties of populations of organisms that transcend the lifetime of a single individual. The ontogeny of an individual is not considered evolution; individual organisms do not evolve. The changes in populations that are considered evolutionary are those that are inheritable via the genetic material from one generation to the next. Biological evolution may be slight or substantial; it embraces everything from slight changes in the proportion of different alleles within a population (such as those determining blood types) to the successive alterations that led from the earliest protoorganism to snails, bees, giraffes, and dandelions."
-- Douglas J. Futuyma in Evolutionary Biology, Sinauer Associates 1986
or
evolution can be precisely defined as any change in the frequency of alleles within a gene pool from one generation to the next.
-- Helena Curtis and N. Sue Barnes, Biology 5th ed. 1989 Worth Publishers, p.974
Darwin's definition of evolution: natural selection has gradually caused all lifeforms on Earth to have evolved from a single common ancestor.
Is that what you are asking, or is that too general?

I've got one for you, Mr. "All Genetics Disproves Evolution:"
Scientists Pin Down Sea Squirt Genetics
"The sea squirt enjoys a special place in the hearts of biologists because it provides the first evolutionary connection between invertebrates and vertebrates," Levine said. "You look at the adult and you think it is one simple creature, but if you look at the embryo, you see a clear connection to higher animals. This is our ancient, ancient cousin."
Of course, such information doesn't fit into your paradigm, so you'll be sure to ignore it.
