"Is being born again.... EVOLUTION!?.... survival of the fittest?.. Intelligent design?..."

No.

I would say that "conversion" or "being born again" or, "spiritual re-birth"is as close to the exact opposite of "evolution" as a example can get.

It is an "instantaneous step-function" change -- not a gradual process.
It relies on no known "natural" process or law; it is fully "miraculous" and totally beyond scientific explanation.
It is attributable only to a Divine and miraculous act of God through his Son, Jesus Christ.
It is also the result of conscious acts of decision of the human will: conscious and deliberate rejection of past sins, and acceptance of the almighty, saving Grace of Almighty God.
[...I expect that others (who have personal experience of salvation) can and may add several further insights to this list...]

Salvation is the result of one of the most "un-natural" and unique and non-repeatable events ever observed by humankind: the willful, loving self-sacrifice of the Very Son of God, Jesus Christ. How much more "non-Darwinian" can you get...?

If, OTOH, you are referring to the changes that take place in the life and spirit of one who "has been born again", during maturation of the "new-born" Christian", again, I would say,

"No."

If there ever were a perfect example of of a "guided process" (as opposed to a 'random, 'drunkard's walk' progression [aka "evolution"], I would state unequivocally that maturation of a truly "re-born" believer is that case.

Maturation of the "newly-reborn" Christian is totally under the (non-measurable) influence and guidance of the Holy Spirit of God.
It, like the acceptance of Salvation, requires the willful cooperation of the human recipient.
Although its trajectory from infant to maturation is often perturbed by the influences of our "opponent", Satan, its relentless net upward progress defies all natural laws -- including the second law of thermodynamics.
Humanity, OTOH, sans the influence of Salvation, and biased by the ever-present influence of our sinful nature, does, invariably, exhibit the downward "spiritual trajectory of entropy" -- an inexorable descending path into chaos and degradation. (See tagline...)
[...Again -- I expect that others (who have personal experience of salvation) can and may add several further, welcome insights to this list...]

Bottom line: as one who has invented and developed hyper-sensitive measurement instrumentation, I can conceive of no physico/chemicical/biological phenomenon that is available as detectable, measurable evidence of the experience of being "born again" or of the spiritual maturation of the resulting Christian.

"Evolution"?

"No."

Divine, miraculous Providence?

"YES."
