All animals are created equal when it comes to their ability to adapt to living conditions. But not all animals use the same dominant hand to perform daily chorus. A recent study has come to the surprise of researchers that discovered true-handedness in other species than primates. If in the past we thought that only primates tend to use more one hand over another, nowadays studies show a more compelling outcome.
Kangaroos rely on their left hand for a number of specific activities, such as reaching for branches of trees, picking leaves or grooming. The left hand characteristic was found mostly among red and eastern grey kangaroos.
In fact, all kangaroos are lefties, as study shows. All kangaroos use the left hand as dominant hand and support for a various range of activities. The entire research is published in the journal Current Biology, where we can entirely observe and analyze the conclusions researchers came up with.
It seems that not all marsupials show exclusive characteristics when it comes to using a dominant hand over another. Red necked wallabies are ambidextrous, meaning that they use both hands with equal skill. Animals that spend time clinging on trees show less proof of the handedness quality.
Kangaroos are also known to walk on their tails that offer balance and support for movement. They move by jumping and the strong tails they are designed with help them maintain equilibrium and gain strength.
In terms of diversity, kangaroos are known by four species, namely the red kangaroo, the western gray, the antilopine kangaroo and the eastern gray kangaroo.
A following research is set to study marsupial brains, study that may lead to better understanding of their mental conditions. Autism is widespread among kangaroos and an extended study on their brain activity may unveil clues on the reason why this condition affects them. Handedness is known to have a strong connection to the neurological disorder found in these wild animals.
Kangaroos live in communities led by the biggest male kangaroo and their natural habitat is found in Tasmania and Australia. They like places covered in green forests, grassy areas and savannahs.
All the findings are highly important, as any proof that offers insights on true handedness in bipedal species contributes to the general study of brain symmetry and mammalian evolution, according to a team of ecologists that closely observed wildlife.
