Dracunculus and Dogs

I think the answer is that dogs are not the intended pollinator, flies are. Insects and mammals are detecting different chemicals in the same scent, even if it is real rotting meat, and they have different odour receptors that have evolved independently.

If the Dracunculus plants have had a mutation that produced a scent which was attractive to mammals in it's evolutionary history, it had not been effective in producing many pollination events and it has not reappeared commonly.

Mutations that lead to reproductive success can be passed on to future generations. This means the production of insect attracting chemicals in this case.

Subject: [pbs] Dracunculus and Dogs

Some time ago I mentioned something about the rotting meat smell of
dracunculus when in bloom and how odd it was that dogs totally ignored it.

Someone did offer an explanation but I cannot find it.

Anyone? An explanation / theory / suggestion - scientific or otherwise?

It's academic, in any case, as after years and years of dracunculus in
my garden it failed to show up this year.
