New animals are the same as old animals

The comment gets made that there are animals today that are the same as they were millions of years ago. And guess what, that is true. So, that means that evolution is not true, correct? After all, all animals evolve.

Not exactly. All animals have evolved and all animals can evolve, but that does not mean that a species cannot find a niche it is successful in and stay there. The misunderstanding is that evolution always changes a group. This is only true when the change is beneficial. If the group is already successful and continues to be successful, then new mutations will not be beneficial and will not change.
