The compound behaviour of primates (aka social science) does not follow the laws of physics. Scientifically the concepts don't transfer. To think they do is a classical error, enjoy Shannon* :)

Most human tribes have far too much at stake to just simply place all their trust in "face value". Google the massive social and cultural implications of infertility. Also, see to what lengths human primates go to ensure that the offspring's chances are optimal: the institution of marriage, the downpayment of dowries, a demonstrated sign of financial well-being, the social stigmatisation and worse of adultery, etc, etc.

The atom’s existence is guaranteed (more than less:), ours is not:)
