I think the creationists in this thread have nicely demonstrated one of the frustrating difficulties in dealing with creationists on the subject of evolution. So many are willing to demand specific answers for certain things that either require incredible depth of knowledge or answers have yet to be found.
Yet, at the same time, they frequently
ignore existing evidence or answers that have been found. For example, there's currently a thread on
endogenous retroviruses, which is startling evidence for common ancestry, yet creationists have given it a wide berth. Why not go there and learn and try to tackle some of the issues being raised?
Or, you have sites like talk.origins which contain extensive articles (complete with even more extensive lists of references to further reading) like the
29+ Evidences for Macroevolution and the
Transitional Vertebrate Fossils FAQ (both of which contain evidence of chimp/human common ancestry, btw). Yet, most creationists appear not to have heard of such resources of information and even fewer are willing to do a little reading.
Lastly, when I see creationists ask seemily innocuous questions like "how did DNA evolve" or "where's the evidence for human evolution", I can't but get the feeling these people wouldn't even be able to understand the evidence even if presented it. Why? Because the answers to these questions are
bloody complicated. Heck, I doubt most people would know what DNA stands for without the help of a Google search, let alone how it even works. Or what the differences between
Homo erectus,
Homo habilus, and
Homo neanderthalensis are. Yet, they still demand all the answers on a silver platter.
My advice to these people is simple: Read. Go to a library and start looking up books and journals. Go to web sites like talk.origins, pour over the material there. And look up references. Don't just come to a web forum and expect to get all the answers in a nice, neat package. It ain't going to happen. Not because the answers don't exist, but rather that the scope required to answer such questions is beyond what you'll get with a few simple paragraphs on a forum.
