Are Kangaroos Left-Handed?

The kangaroo, a marsupial species, is thought to exhibit left handed favorability. Researchers in Australia have studied two bipedal species of kangaroos and one bipedal species of a wallaby. The study showed that the two kangaroo species favor their left hand in all activities, whereas the wallaby favors the left hand in activities such as feeding. However, quadruped marsupials are known to have relatively weak forearms and do not exhibit hand favorability.

This new information is strange because true 'handedness' was thought to have evolved from primates and eventually humans. This shows that there is a connection in the evolution of the kangaroo and other handedness species. Although, most handedness mammals are right handed, rather than left handed. I found this study interesting because it shows more information on the kangaroo and their behavior. I always thought they were a strange species, because of their habits and characteristics. This new insight adds to my previous perspective of the strange, but unique species.

  1. Left-handed kangaroos look to be pretty awesome! I would wonder why only bipedal kangaroos are left handed when most bipedal mammals are right handed. Would we have a common ancestor with bipedal left handed mammals?
