    Did you know Kangaroo’s are Left-Handed?

    Humans and some other primates exhibit “handedness,” or the tendency to use one hand more naturally than the other. Scientists once thought this was a unique feature of primate evolution, but more recent research suggests handedness is also common in kangaroos.

    Based on research with red kangaroos, eastern greys, and red-necked wallabies, researchers have found the animals are primarily left-handed, using that hand for tasks such as grooming and eating about 95% of the time. Their hands also seem to be specialised for different types of work, with kangaroos typically using their left hand for precision and their right for strength. This challenges the idea that handedness is unique to primates, researchers say, noting it may be an adaptation to bipedalism.

      I don’t remember where I heard it, but it seems some birds sometimes show handedness, like cockatoos, the birds that have handedness are in average more agile and better at solving puzzles than birds that use both hands equally.

      Dude, what is it with so many like researchers or scientist just automatically default assuming that we are the only species or family that has certain neurological things before any sort of study or basis?

      Like they thought different creature didn’t feel pain and blah blah blah didn’t feel pain, and it’s like, come on. That’s a basic biological response.

      Why wouldn’t we default assume that there’s some underlying pattern or similarity?
