It is the evolutionary scale ranging from the unicellular organism to mammals.
There is no such scale, there is just the assumption on your part that one exists.
Today, to my knowledge, there is no other species above man.
It is the Bible that says mankind was set above other animals. Science generally considers man to be just another animal.
Take a look here:
Palaeos: Page not found
That's a high-level cladogram of how science currently views the phylogenetic class of mammals. You'll notice that humans and their close relatives (hominoidea) do not appear on the top or bottom of the list. Position on the list merely places each clade (branch) in relationship to other clades within the diagram. Homo sapiens is just one more branch on the tree, not the end product.
My original question is: If evolution is a continuous process, then where does it end?
The ToE tells us evolution requires only imperfectly replicating structures. If there are none (all life as we know it ends or somehow begins to replicate perfectly) then evolution will cease. Evolution does not have a goal or purpose.
What will be the next species after man?
Since we cannot (yet) predict what mutations may appear or how they will be filtered by natural selection there's no way of knowing. Think of it like this: those cards haven't been dealt yet. We have a growing understanding of the cards still in the deck and we can make a few predictions (our successor species will probably still have 4 limbs and our general arrangement of bones and organs) we can't say exactly what will be different about them.
When science and the Bible differ, science has obviously misinterpreted its data.- Henry Morris, Head of Institute for Creation Research
