There is empirical evidence despite the repeated creationist assertions that there is none.
I was actually using it as a stalking horse, to draw out the arguments against transitionals, and if we get past the obvious misrepresentations (such as 'it can't be a transitional because it is a bird') then we would be at a point where we can look in a more unbiased way at the evidence for other examples.
If I supplied my other example you would just say "but it is an insect" or "but it is a fish" or "but it is a reptile" or whatever group I was planning on examining. Using Archaeoptryx as a stalking horse will give us the opportunity to deal with the question "if it is part of one taxonomic group, how can it also be a transitional?" which is the question creationists don't ask.
It was not intended to deceive, though, and I have presented Archaeoptryx. as evidence now. If we get anywhere with that then I will proceed with others, but Archaeoptryx is instructive as it will, I hope, eventually lead to a discussion of the actual evidence. That is the point I am aiming at.
Where were we? Oh yes, you were telling me that it is a bird and I said that I knew.
Phil in my opinion you are correct that the fact that even though humans have classified Archeaoptryx as a bird, this doesn't necessarily mean that it is not a transitional fossil...
However as it stands I do not believe that just using Archeaoptryx is enough to actually prove it is a transitional...
Yes a transitional needs features of 2 different types of species and is the link between these species, however only having one organism doesn't fill the hole... In reality we "should" see lots of different intermediate fossils.
For example: one with a lizard with stumps signifying wings, then developed a bit more, then with a more bird like skeleton, then a bit more bird like then even more then archeaopteryx then birds
As you see there is a massive gap from lizards, (or dinosaurs) to birds in reference to the avian lung design, bone density and skeletal form, and the apperance of feathers..
Perhaps dinosaurs had feathers... (perhaps!??..lol).. However this doesn't solve anything as there would need transitional forms found that demonstrate how these dinosaurs evolved these feathers.. As far as I know, in terms of the fossil record, feathers just popped into existance
As such until a line of decent can be found, with transitional fossils demonstrating all the small changes, (that evolution states occurs over millions of years), then there is no proof of transitional fossils, and is inference on what "could" have happened
Also thanks for the compliment before
