I wouldn't have thought there was anything unusual about this statement in this forum until I saw at the bottom of your post that you believe in God. I was not aware of that until now. If you believe in God, why do you need evidence? if He said He created everything, why don't you believe that?
I do not need evidence and have made that pretty clear in general. It is one of the reasons I find the entire intelligent design movement to be both humorous and a sign of weak faith.
I believe that God is the creator, I just do not subscribe to the claim that His creation follows the story of Genesis. Since the evidence indicates that the story of Genesis cannot be literal, it must therefore be an analogy to be read as an allegory. Following that practice changes nothing about my personal belief.
We were talking about birds, reptiles and fish. What else would I have meant by "category of creatures" other than something general like that. Probably doesn't call for an evaluation of my knowledge about taxonomy.
I am still not clear what you mean. Birds, reptiles and fish are different classes of vertebrates. Each of those classes contains species that are transitional and there are transitional species in the fossil record that can be placed in each of those classes. Placement in a classification does not eliminate the possibility of being a valid transitional form.
Not at all. My opinion is that God designed archaeopteryx with characteristics suited for survival in its given environment during its time on earth. The sheepshead fish has teeth that look remarkably similar to human teeth. Very odd looking, but It has nothing to do with non-sheepshead fish ancestry or a link to humans. It's all about cracking open the clams, oysters, crabs, and such that make up its diet.
How can you know that God personally designed it? I believe that God can enact His will, but He can also allow things to happen without interfering. All the evidence would indicate this is how He has allowed life on Earth to evolve. I do not bother to argue where God has engaged in the process, since I cannot read the mind of God or have any evidence indicating divine activity.
"Ancestral characters," as if the ancestry in knowable.
It is knowable, through the fossil record, through examination of extant species, through genetics. It turns out that some birds, including chickens have retained the genes for growing teeth. Recent experiments carried out in chicken embryos to re-activate these genes lead to embryos with theropod-like teeth.
"A single species away" -- it still comes down to speculation.
It comes down to observations, evidence and reasonable, logical conclusions based on that observation and evidence in light of sound theory.
