Creationists don't deny that animals are related. What we dispute is how they got there.
Your thread falsely implies that a simple copying error accounts for the change between animals. But what your thread doesn't show is ALL of the differences in genetics between those different animals. It's a lot more than just one change.
The differences are better explained by "Common Design". Humans share 50% of their genes with Bananas. That doesn't mean that humans came from bananas or shared a common ancestor with bananas.

Your keen analysis makes it more likely we are related to bananas.
