Of course felines evovled into felines.
Of course hominoids evolved into hominoids.
Of course your theory is demonstrably false. How can I be so sure? Each generation, mitochondrial DNA develops random mutations, but it does so at a constant rate. We can compare individuals mtDNA and tell how many generations ago they shared a common ancestor. If what you are saying is correct, all cats should share a common ancestor within the last 6000 years.
They don't.
