Mad professors raised monstrous sundews and pitcher crops on uncooked steak till their ravenous creations turned and ate them too.
The younger Arthur Conan Doyle caught nearer to the science in a yarn that includes everybody’s favourite flesh-eater, the Venus flytrap. Drawing on brand-new botanical revelations, he precisely described the two-lobed traps, the best way they captured bugs, and the way totally they digested their prey.

Cellular animals did the consuming; crops have been meals and couldn’t transfer—in the event that they killed, it should solely be in self-defense or by chance.

He confirmed that the leaves of some crops had been reworked into ingenious buildings that not solely trapped bugs and different small creatures but additionally digested them and absorbed the vitamins launched from their corpses.
