Last week, science writer Jennifer A. Kingson wrote in an article in the New York Times Science Section…
“What’s big and wooly and making a comeback on the Tibetan-Qinghai Plateau?” 
“The yak population there had been decimated by hunting, much like the American bison population, so the expedition team, which included Chinese and American conservationists, was understandably best pleased to see so many of them up there.”
Well done, yaks. Keep on going forth and multiplying!
 OK. BIG question. Is it ‘wooly’ or ‘woolly’? Talmudic sages for generations have pondered this profound question. Here’s the answer. The English (i.e. proper) spelling is ‘woolly’ (two Ls). “Wooly” (one L) is the American spelling. It’s kind of like the difference between humour and humor, travelled and traveled, aluminium – aluminum, burnt and burned.
