Editing Handshake (section)

==Chemosignaling==
It has been discovered as a part of research at Israel's [[Weizmann Institute]] that human handshakes serve as a means of transferring social chemical signals between the shakers. It appears that there is a tendency to bring the shaken hands to the vicinity of the nose and smell them. They may serve an [[evolution]]ary need to learn about the person whose hand was shaken, replacing a more overt sniffing behavior, as is common among animals and in certain human cultures (such as [[Tuvalu]], Greenland or [[Rural area|rural]] [[Mongolia]], where a quick sniff is part of the traditional greeting ritual).<ref>{{cite journal|author1=Idan Frumin|author2=Ofer Perl|author3=Yaara Endevelt-Shapira|author4=Ami Eisen|author5=Neetai Eshel|author6=Iris Heller|author7=Maya Shemesh|author8=Aharon Ravia|author9=Lee Sela|author10=Anat Arzi|author11=Noam Sobel|title=A social chemosignaling function for human handshaking|journal=eLife |volume=4|date=3 March 2015|doi=10.7554/eLife.05154|pmid=25732039|pmc=4345842 |doi-access=free }}</ref>
