evolution - Are there genetic similarity between humans and pigs that don't exist in chimps?

Chimps are our closer relative.

Any genetic similarity between humans and chimps must exist on the common ancestor.

Pig branch out sooner. So, any genetic similarity between humans and pigs must be on common ancestor between humans and pigs. That must be on common ancestor between humans and chimps.

But chimps may evolve differently.

Hmmm... I am confused.

Actually is there any?
