YEC Geo's curator insight, February 9, 2015 12:09 PM

The authors state:  "It is remarkable to be able to confirm that these ancient proteins share many of the characteristics of modern mollusk proteins."

 

The sheets of protein are more than 1 cm across.  Seems to me that's plenty enough material on which to do C-14 dating.

Global warming:

Many say that the issue of global warming can be directly attributed to the emission of fumes from the vehicles that human kind operates. But looking at the pattern of global warming and arctic freeze overs, patterns do change and fluctuate every thousands of years....is this global warming a natural change or are the actions of humanity bringing about this warming as an after effect?
