Probably nature itself gave man the ability to lie so that in difficult and tense moments he could protect his nest, just as do the vixen and wild duck.
Sadly, as with so much about history's heroes, it's the spotting of potential fame that's the difficulty, whether it's publishing their poems, hanging their paintings, or buying their old underwear.
