Girl researches for 3 years to prove specimen is Japanese wolf
From Asahi Shimbun:
TSUKUBA, Ibaraki Prefecture–Hinako Komori quickly recognized that a stuffed specimen at a museum storehouse was likely a long-extinct Japanese wolf. But the elementary school girl faced difficulty trying to convince adults of her theory.
It took Komori, now a 13-year-old second-year junior high school student in Tokyo, more than three years to get the science world to confirm the animal was indeed the sixth known specimen of the long-lost wolf.
