Again, look in the mirror. If you are an exact clone of all your ancestors and there is not the slightest difference then no change or evolution has occurred. However if there is any change, no matter how small evolution has occurred. Evolution is a fact and a occurring fact and is proved by the observation that no two of the 6.7 billion people that exist on earth are a exact duplicate. The theory of evolution is explanation of a fact (evolution) and not a argument that evolution exists. To deny evolution (change) would deny your own existence. Your evolution occurred by reproduction.
>Your evolution occurred by reproduction.
That sounds more like revolution than evolution.
There is no such thing as perfect replication via sexual reproduction, since male and female are categorically dissimilar. There can never be an instance in which any given offspring can represent both at the same time.
Imperfect replication, in and of itself, does not infer evolution...unless you're willing to state that sexual reproduction is incompatible with every other theory out there, including, and not the least of which, creationism.
"and is proved by the observation that no two of the 6.7 billion people that exist on earth are a exact duplicate"
Offering facts not in evidence. You have no way of determining that this is the case; it is merely an idea. There is no way to test or falsify the statement you made.
