Editing Pre-Columbian transoceanic contact theories (section)

=== Plant genetics ===
The genetics of several plant species has also been used to support pre-Columbian contact via the Pacific. For example, there is a genetically distinct sub-population of coconuts on the western coast of South America. This has been suggested to be evidence of introduction by Austronesian seafarers.<ref>{{Cite journal |last1=Baudouin |first1=Luc |last2=Lebrun |first2=Patricia |date=2009-03-01 |title=Coconut (Cocos nucifera L.)
