I wonder how it became extinct in the Middle Ages. It annoys me when an article gives intriguing info like that without bothering to explain it!
Very interesting though.
[I wonder how it became extinct in the Middle Ages.]
I'm sure all the industrial pollution from the greedy corporations killed it off after the Republicans succeeded in gutting environmental laws so their rich buddies could have more money to stuff into their back pockets.
I'm also sure George W. Bush had a personal hand in it.
