There’s a great post on Pollination biology in the greenhouse at the Phytophactor. It’s easy to individualise species when talking about evolution, so that one honeybee becomes THE honeybee or one rose becomes THE rose. Then you end up talking about how the bee pollinates the rose. The phytophactor shows that this way think can break down when you look at how flies pollinate Stapelia. The answer to the puzzle he poses requires thinking about populations.
