Editing Handedness (section)

== In other animals ==
[[Kangaroo]]s and other [[Macropodidae|macropod]] [[marsupial]]s show a left-hand preference for everyday tasks in the wild. 'True' handedness is unexpected in marsupials however, because unlike [[Placentalia|placental mammals]], they lack a [[corpus callosum]]. Left-handedness was particularly apparent in the red kangaroo (''Macropus rufus'') and the eastern gray kangaroo (''Macropus giganteus''). Red-necked (Bennett's) wallabies (''Macropus rufogriseus'') preferentially use their left hand for behaviours that involve fine manipulation, but the right for behaviours that require more physical strength. There was less evidence for handedness in [[arboreal]] species.<ref>{{cite journal |last1=Giljov |first1=Andrey |last2=Karenina |first2=Karina |last3=Ingram |first3=Janeane |last4=Malashichev |first4=Yegor |title=Parallel Emergence of True Handedness in the Evolution of Marsupials and Placentals |journal=Current Biology |date=July 2015 |volume=25 |issue=14 |pages=1878–1884 |doi=10.1016/j.cub.2015.05.043 |pmid=26096972 |bibcode=2015CBio...25.1878G |doi-access=free }}</ref> Studies of dogs, horses, and domestic cats have shown that females of those species tend to be right-handed, while males tend to be left-handed.<ref>{{cite journal |last1=Wells |first1=Deborah L. |last2=Millsopp |first2=Sarah |title=Lateralized behaviour in the domestic cat, Felis silvestris catus |journal=Animal Behaviour |date=August 2009 |volume=78 |issue=2 |pages=537–541 |doi=10.1016/j.anbehav.2009.06.010 }}</ref>
