We might superficially then claim chimps and humans must have descended from a common ancestor. And we could rinse and repeat and say, "we're more similar to fish than to trees as well so we fish and humans must have descended from a common ancestor of fish and humans."
The problem then is we follow the logic carefully, we must therefore conclude we didn't evolve from fish, at best fish and humans descended from some unspecified a common ancestor.
So let me for the sake of argument assume evolutionism is true. What can we conclude from these diagrams:
Evolutionists however will give the following non-sequitur:Vertebrates descend from Vetebrates
Mammals descend from Mammals
Primates descend from Primates
Humans descend from Humans
Therefore: Humans descended from Humans
Vertebrates descend from Vetebrates
Mammals descend from Mammals
Primates descend from Primates
Humans descend from Humans
Therefore: Humans descended from Fish![]()
Here is a diagram at the anatomical level that shows a very nice hierarchical pattern from universe review.

and then regarding the bone morphogenetic proteins

What these diagrams show is that Fish will not give birth to anything but something fish like. It won't give rise to Primates!
As Michael Denton pointed out, superficially the structure of diversity in the biosphere suggest common descent, but the problem is it also suggest that there won't be any transitionals even in principle. Hence a careful study of the diagrams might lead one to think special creation is a better explanation since it is evident that fish don't give any hint of being ancestors to primates.
