Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.
Schweitzer answered the challenge by testing with antibodies.
He said that his team and the laboratories they employed took special care to avoid contamination.
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.
RATE found radiocarbon at levels above the background blanks in all samples.Now, a team of secular scientists used radiocarbon to argue against the preservation of dinosaur collagen, but unwittingly affirmed the Flood option.Examples of radiocarbon discoveries that are out-of-place for evolutionary time keep stacking up.They reason that since something that old can no longer have radiocarbon, therefore all of the sample’s measured radiocarbon must have come from modern sources. But where would all that recent radiocarbon come from?
