That is a good example of how change in species over time dilutes and corrupts the original genetic code, making it weaker and less able to survive over time.
Evolution over time destroys, since harmful genetic mutations are much more common by far, than beneficial mutations.
The human genetic code is also failing and becoming more corrupted the more time goes by.
Evolution appears to actually work in reverse, until species can no longer function in their environments and eventually go extinct, just as the human race will if given enough time.
Shouldn't you be blaming God for that? I mean, these are your words, right?
"Yes, species change over time. God created this ability to enable the survival of species over great spans of time."
