petrushka.googol Posted January 6, 2016 Share Posted January 6, 2016 When I shake someone's hand my brain gets connected to my hand, which in turn gets connected to that person's hand, which connects to that person's brain. (my brain to his). Oxytocin and noradrenaline get secreted and the person feels good. How did the handshake (as we know it today) originate ?

Strange Posted January 6, 2016 Share Posted January 6, 2016 The handshake is thought by some to have originated as a gesture of peace by demonstrating that the hand holds no weapon.[6][7][8] It has been discovered as a part of a research in the Weizmann Institute, that human handshakes serve as a mean 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 evolutionary 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 (un Tuvalu, Greenland or rural Mongolia, where a quick sniff is part of the traditional greeting ritual).

Xalatan Posted January 21, 2016 Share Posted January 21, 2016 (edited) Kinda odd that oxytocin is released in social interaction as well as labour and lactation. Edited January 21, 2016 by Xalatan Link to comment Share on other sites More sharing options...

petrushka.googol Posted January 23, 2016 Author Share Posted January 23, 2016 Evolution is big on reuse. Did this gesture have simian antecedents ? Link to comment Share on other sites More sharing options...
