This is an incredible performance. What did you say in post 13? "Look at the tree," you urged. What tree? Anyone would have assumed the tree in the posted article, not the tree in your backyard.
This tree.
That is a tree of common descent. Every item on there has a common ancestor down the tree with every other one.
Look there. Cetaceans and hippos have a common ancestor there. In that picture, the two branches meet down the tree.
Your latest post lists at least some of the extant artiodactl groups. All the species alive today are on the branch tips, not down the tree. You don't find your own ancestors among your siblings and cousins.
Before you get dumb in some other direction, there are still apes today but your ancestral line also goes back through apes. There are still reptiles today but your ancestral line goes back through reptiles. There are still fish today but your ancestral line goes back through fish.
The modern versions are not your ancestors. They're just sort of throwbacks toward your ancestors.
