Research scientists have recently found that kangaroos in zoos and sanctuaries use body language to ask humans for help, much like horses and dogs do. The researchers think this suggests that wild animals can learn to engage in inter-species communication just by being around humans.

Previously, researchers thought that only domesticated animals had the ability to communicate with humans, said Alan McElligott at City University of Hong Kong.

Kangaroos in Australia have never been a domesticated animal. In Australia, there are about 50 million kangaroos that roam in groups, called mobs. But there are also thousands of kangaroos, and other marsupials such as wallabies and pademelons, that live in zoos, parks, and sanctuaries.
