Jan 16, 2014 at 9:20 | comment | added | Chris♦ | Some comments from me: Most substances that smell bad contain some kind of sulphur components - and we are really sensitive to them. If I open a bottle with beta-Mercaptoethanol in a lab (and not in the fume hood) it will only take seconds until someone else starts protesting and opening up windows. Some of these chemicals are highly toxic (for example hydrogensulfide), so it makes sense that we are aware of them. Regarding the flowers: There are some flowers, that smell really awful, have you ever been close to a Ginkgo tree that is blossoming? Not very nice I can tell you... | |

Jan 16, 2014 at 7:09 | comment | added | rg255 | Generally speaking flowers smell good to pollinators - there are a limited number of possible scent chemicals and/or common arrays of "good" smell receptor in the world so I would suggest that there is likely to be some crossover - but that is pure guess work | |
