The evidence that the dodo bird (Raphus Cucullatus), extinct since 1681, could be alive is not quite as solid but still interesting. A night vision video recently uploaded to the Internet shows what appears to be a live dodo walking past an iguana.
Interestingly, hard-boiled eggs do not keep nearly as long as raw eggs, which can last three to five weeks in the refrigerator. There is a good reason for this. When a hen lays an egg, it puts a naturally protective coating on the outside of the shell.
Hard boiled eggs can be stored for up to a week in the fridge. Raw eggs should never be kept longer than 21 days after they've been laid, and should ideally be stored in the carton they came in. As for egg whites, you can keep them in the fridge for up to a week, or you can even freeze them.
