The evolution of carnivorous plants is one topic in particular which befuddles me. Modern genetic evidence indicates that the Venus Fly Trap and all of the Old-World pitcher plants (except Cephalotus, which is a completely separate lineage) share a common ancestor with the Sundews and probably originated from ancestors which would be considered sundews by modern definition.
​
I can see how a Venus Flytrap may have evolved from a sundew; they look very similar at first glance too. I have my own ideas on how exactly the "bear trap" first appeared, but that's not the topic. I just honestly cannot imagine what kind of processes would have been needed to go from a flypaper trap to a pitcher. Does anyone here have any better insight than I do? This one has been giving me a hard time.
