IANABK (I am not a bee keeper) but I suspect there are other bees that would love to pollinate a greenhouse full of flowers with easy access at all heights. I'm thinking that in nature only one species shares the same space and prefers vanilla flowers but that's not the same an having only one that CAN do it.

Pollination often has to do with having the right anatomy in the right configuration on bee and flower. Orchid species (like vanilla) in particular often have this single species coevolution trait for whatever reason.

One theory might be that the higher specificity would lead to better firtilization rates when one kind of bee sticks to one kind of flower.

In the wild, in Mexico, vanilla is pollinated by one particular species of bee, that only lives in Mexico. Even there, commercial producers rely on hand-pollination.

Interestingly vanilla originates from Mexico and not Madagascar. The plant was introduced to Madagascar for cultivation in the 19th century.

It's amazing really all of the plants that originated from indigenous Mexican cultivation. Corn, tomatoes, chili peppers, squash, chocolate, vanilla, avocado, and more! The fact that Italians didn't have peppers nor the Irish having potatoes until after columbus always blows my mind.

Indeed. Read "The Columbian Exchange" book by Alfred W. Crosby. Imagine Hungarians without paprika and Indian cuisine without peppers. :-)
