A mother polar bear has made the decision to adopt - a move that scientists say is extremely rare - and the new family was caught on video.
Researchers had tagged the five-year-old mother, also known as “bear X33991,” and her 10-to-11-month-old cub in the spring in the northeastern Canadian province of Manitoba. Come fall, the scientists noticed she had another untagged cub with her as her family grew, this time by seeming “adoption.”
