Until now it has not been clear which plant the Venus flytrap and waterwheel evolved from. Waller and his colleague Thomas Gibson now think they have the answer, which they have published in the journal New Phytologist. According to them it detected prey and tried to respond. Then the plant would have had to find a way to become selective, so it only tried to trap live prey and not any detritus that landed upon it. Finally, it must have evolved its tentacles into sensory hairs and teeth that detect and wrap around prey, respectively, while also losing its sticky glands and growing new digestive glands capable of digesting the victim's corpse.”
