About Arctica
Expertise
I can answer a broad range of questions about the history of life on Earth, from the origins of single-celled organisms to the evolutionary history of plants, invertebrates and, particularly, vertebrates. I am also experienced in debating creationists and can provide rebuttals of many common creationist arguments. I cannot, however, answer questions about archaeology, and I generally cannot answer technical questions about rocks, bone structures or fossils - I am a reader, not a digger.

Experience
Many years of research into the history of life on Earth. I have no formal qualifications, but what I lack in technical expertise I make up for in range. I have spent many months debating creationists on the BBC''s science forum, and have consequently thoroughly researched a great deal of creationist and anti-creationist material.

The author of this article challenges the readers to cite a case of unfossilized dinosaur bone. The Smithsonian, and many other journals have reported on the find of T. rex bone complete with marrow cells and red blood cells.

As far as "Caron 14 has not come to balance in the atmosphere," this can be clearly seen in the recent Nature article at http://www.nature.com/stemcells/2009/0904/090409/full/stemcells.2009.58.html

"After the Second World War, tests of nuclear bombs spewed carbon-14 pollution into the atmosphere. This isotope was incorporated into plants and the people who consumed them."

Who's to say that similar events did not occur resulting in incorpration (or lack thereof) with different radioisotopes?

Thanks again for posting to allexperts!
