Amelia Earhart's Resting Place Fingered?

Apparently, a finger fragment has been found that may tie Amelia Earhart to a remote island. I've been captivated by the Amelia Earhart story for years, but I find it highly doubtful that she was ever on the island in question. No plane has ever been found, no "Amelia was here" etchings, no absolute proof that she was there. The Island would have provided more than enough food and water for one or two people, and people from a British expeditionary group landed on the island and colonized it only 18 months later. If she was there, she was injured and died quickly, which would explain the lack of "Amelia was here" sort of stuff, but it doesn't explain the complete lack of airplane wreckage.
