I didn't say they are born liars and thieves - just that they do deceive and detect deceit, and have emotions ready-made for deceit-based situations. All apes, including us, have those emotions, and communicate those emotions in ways that cannot be learned as they (facial expressions of emotions in humans) transcend culture.

And no, we aren't better at it because we are ALSO hardwired to *detect* deceit. The two abilities go hand in hand - or gene in gene, as the case may be.

There is some evidence that SIDS deaths can be caused by not knowing how to breathe as the glottis changes shape from allowing eating and breathing at the same time, as in infants, to the adult shape that allows choking to death on food, which we are also hard-wired to do by the very shape of our throats. But it's still a bad idea!
