L’Anse aux Meadows:
Dating to c. 1000, this archeological site is believed to be the only evidence of Norse settlement outside of Greenland. It is situated on the northernmost tip of of the Great Northern Peninsula on the island of Newfoundland, Canada. Today, the area is mostly grass and some re-creations, but 1000 years ago it was likely filled with trees that were good for buildings boats and houses. This area is proof that actual Vikings made their way to Canada and settled here for a bit. Amazing.
or they are respectful that not all religions utilize the same calendar...
"When in Rome..."
...I use my own d@$% calendar, and I expect everyone else to accommodate me!!!!!
Darwin has nothing to do with historical timelines.

What we're talking about is the Norse settlements leading to the settling of the North American continent. Greenland because of it's proximity to N. America is the reason it's included.
