According to Christianity Today - General Statistics and Facts of Christianity Today
there are approximately 38,000 Christian denominations in the world.

Why? This question got asked at www.gotquestions.org (which promises 'The Bible has the Answers, we'll find them for you') but I can't say I was impressed with the answer:

The point of these divisions is never Christ as Lord and Savior, but rather honest differences of opinion by godly, albeit flawed, people seeking to honor God and retain doctrinal purity according to their consciences and their understanding of His Word.

It's pretty obvious that if the "point of these divisions"  were "Christ as Lord and Savior" it wouldn''t be a Christian domination. I also assume that only 37,999 of these godly people are "albeit flawed". The remaining  one being the one that is right?

I can't help noticing that the evolution of Christian Dominations as pictured in wikipedia.org/wiki/List_of_Christian_denomination looks like ..., eh ..., evolution?

Why wouldn't it? For evolution you need only three things:

1. Variation
2. Selection
3. Inheritance

Religion is all about inheritance. Getting other people - your children, at the very least, or just any body, if you are an evangelical religion - to believe what you belief and to belong to your religion.

It has selection: if nobody believes and nobody belongs, it is dead.

And it has variation: "differences of opinion by godly, albeit flawed, people".

According to the ("just a") theory of evolution, given those three factors you must get evolution. Such as, for example, 38,000 different 'species' of Christianity.
