This is likely why amines also smell bad (cadaverine and putrescine, for example, being common products of biological decay), as well as many carboxylic acid (butyric acid, for example, is produced when certain fats break down). Being averse to these odors is therefore probably an evolved and advantageous genetic trait. | |
