Editing Handedness (section)

== Evolution ==
Some non-human primates have a preferred hand for tasks, but they do not display a strong right-biased preference like modern humans, with individuals equally split between right-handed and left-handed preferences. When exactly a right handed preference developed in the human lineage is unknown, although it is known through various means that [[Neanderthal|Neanderthals]] had a right-handedness bias like modern humans. Attempts to determine handedness of early humans by analysing the morphology of lithic artefacts have been found to be unreliable.<ref>{{Cite journal |last1=Ruck |first1=Lana |last2=Broadfield |first2=Douglas C. |last3=Brown |first3=Clifford T. |date=2015-05-07 |title=Determining Hominid Handedness in Lithic Debitage: A Review of Current Methodologies |url=http://dx.doi.org/10.1179/2051618515y.0000000009 |journal=Lithic Technology |volume=40 |issue=3 |pages=171–188 |doi=10.1179/2051618515y.0000000009 |issn=0197-7261}}</ref>
