Evolution of Nepenthes pitcher plants.

Wiki has a page on Protocarnivorous Plants that is interesting and gets into what the intermediate forms could be like. For example:

---

many sun pitcher plants (Heliamphora) and the cobra lily (Darlingtonia californica) would not be included on a roster of carnivorous plants because they rely on symbiotic bacteria and other organisms to produce the necessary proteolytic enzymes.

Heh, don't humans rely on bacteria in their belly for digestion too? Unless herbivory is defined by what you eat as opposed to how you digest it Conversely, it seems they're definining protocarnivorous plants by how they digest what they "eat".Regardless, your point is not lost.Edited by Catholic Scientist, : No reason given.
