[Alter Kaker]

Well, here we have evidence that either protein decay rates projected back into time are grossly wrong *or* time projections are grossly wrong. Take your pick.

Proteins don't have "decay rates." Proteins decay, but they do so unevenly depending on the environment. The human proteins in Egyptian mummies, for example, clearly outlast human proteins in other environments.

Clearly this study shows that in certain circumstances, proteins can be preserved for an exceedingly long period of time.

[GourmetDan]

"Clearly this study shows that in certain circumstances, proteins can be preserved for an exceedingly long period of time."

The only thing this clearly shows is that you *assume* that 'in certain circumstances, proteins can be preserved for an exceedingly long period of time'.

For without the assumption of 68 MM year age, the notability collapses.
