The Real Reason We Yawn
December 16, 2008
I have seen monkeys yawn -and quite profusely at that. As this appears to be a common trait of both man and monkeys it has set me to wonder how this feature evolved in the first place. The conventional explanation often heard is that yawn is an indication of boredom. But is there anything like boredom in animals like monkeys if so what is it that they are bored of ?. If the monkeys are in our proximity it might be quite real that they are utterly bored with us knowing well that how tiresome some of us could be. But now comes the scientific explanation and I am somewhat relieved. Next time I inadvertently revert to this ancestral trait in presence of some valued guest I have a cool explanation.
