To just say ToE and leave it at that without the details is just so impractical and unfruitful to any discussion re: such.
What is fuzzy about biological traits forming a nested hierarchy that supports the hypothesis of common descent? Understanding the argument requires only a small effort with simple concepts and data. You don't need to know about "fine tuning" arguments, theistic evolution vs. ID distinctions, atheism vs. theism, or any number of other red herrings.

The fact we see many similar biological systems, but different... one my wife was talking about this morning to me, mothers lactating milk whether humans, cows, cats or dogs are all systems very similar in purpose and function, and yet these systems are otherwise quite different and unique to each.
You're over-thinking. For example, for the mammal grouping, the common descent argument from biological traits uses just the existence of mammary glands, not which variety. Other groupings throughout the nested hierarchy use similar objective yes/no traits. Another example grouping (at a different level in the hierarchy) might require the trait of a bony vertebrae: Squid->no. Fish->yes. Human->yes.
I think you're under thinking.
I'm not sure you understand what I'm getting at, which is "evolution/ToE" are used but rarely defined.
People just launch into discussion falling on one side or the other.
See, you appear to associate "evolution" with biological traits forming a nested hierarchy that supports the hypothesis of common descent...
Nested hierarchies / common descent is not what I'd classify as "evolution" or ToE. Such is simply circumstantial evidence.
And this evidence can also equally support non-evolutionary scenarios that accommodate such. So this can't be called "evolution".
Rather, in any discussion of "evolution" I'm personally concerned to understand how the natural "evolving" works.
So I think your response actually shows the issue with just saying "evolution" or "ToE". (and I equally took this up with ACB in another thread)
People have all these concepts that you attach to the word "evolution" which are more/less relevant. So they always talk past each other.
Again, when I talk of evolution I'm more interested in the "evolving". What mechanisms?
And for me I'm very interested in information theory. Perhaps because I started out in Information Technology.
So now we know about biological information, how did it all get written and come to be?
As an aside, specific theories of common descent have been largely built up around common features.
It is rather easy to look at two species and hypothesize that this feature or that feature looks similar and so must have had a common ancestor, even perhaps be within the same species.
This is somewhat superficial in my opinion, and much better to go by biological information (e.g., DNA). Otherwise biologists are really just determining species and lineages by their cover.
Thanks to more contemporary scientific work, we are more and more opening the covers of a particular creature to read their biological information.
As this happens, many species classified as one based upon similarities in their looks are increasingly being seen as distinct species.
So unless a good amount of research has been done at the "information" level, then the pathways we see are likely superficial at best.
It doesn't disprove common descent, but does start spinning it on its head in all different directions.
Anyway, when I talk "evolution" I'm not meaning common descent or all those pathways and hierarchies you commonly see.
Rather, I'm interested in the "evolving" and what mechanisms are involved. Information theory being applied to biology creates a lot of difficulty.
Because now, we're not just seeing talking in terms of "biological features" and a mutation here and there, natural selection, etc.
The terms are actually describing a biological language that needs to have arisen on its own, and its information content
increasing (not just evolving or morphing).
If you will, to me, it is like the evolutionary equivalent to the "Origin of Life" problem
-- how did the initial life come into being (OoL) vs. how did this new information increasingly come into being (biological diversity).
Now if life began complex, with an enormous amount of coded information, then certainly all life evolving from such a rich pool information seems more plausible.
But we're talking very simple life (little to no information) developing into very complex information with reptiles, amphibians, plants, mammals and the like.
So, the information that has been uncovered in biology really causes some headaches I think.
Especially once one understands a bit about information theory and starts to apply this in biology.

I am just over thinking... but, better then under thinking right?
