You yourself provided a link to a discussion debating the creationist extrapolation of this evidence. Clearly, this is insufficient evidence to overturn a legion of evidences against a young earth (most of which I haven't even mentioned yet). Furthermore the whole approach here is, as previously stated, non-scientific, which can be redemonstrated as follows. A real scientific effort would try to reconcile ALL the data, not just cherry-pick his desired conclusion. In this case, the creationist supposedly provides evidence of a young earth (hemoglobin found in dinosaur bones). But if all dinosaur bones are really that young, why don't we find hemoglobin in MANY dinosaur bones? Why is this the only example? Why aren't the creationists adressing that issue? Because they have no interest in the facts. All they want to do is cherry-pick their conclusion and, having found the fruit on the tree, they couldn't care less that their "findings" raise more questions than answered and create more problems than solved. That's not real science.The research for this discovery was done at Montana State University by Mary Schweitzer in a lab supervise by famous paleontologist Dinosaur Jack Horner. The following test were done. And connective tissue was still flexable.You can check the article in scientfic journals out also.
- The tissue was coloured reddish brown, the colour of hemoglobin, as was liquid extracted from the dinosaur tissue.
- Hemoglobin contains heme units. Chemical signatures unique to heme were found in the specimens when certain wavelengths of laser light were applied.
- Because it contains iron, heme reacts to magnetic fields differently from other proteinsextracts from this specimen reacted in the same way as modem heme compounds.
- To ensure that the samples had not been contaminated with certain bacteria which have heme (but never the protein hemoglobin), extracts of the dinosaur fossil were injected over several weeks into rats. If there was even a minute amount of hemoglobin present in the T. Rex sample, the rats immune system should build up detectable antibodies against this compound. This is exactly what happened in carefully controlled experiments.
