conditions that some plants evolved different ways of obtaining nutrients. The

these plants to survive in somewhat hostile environments.
The evolution of carnivorous plants is speculative due to the paucity of
the fossil record. It is believed that plant carnivory may have evolved millions
of years ago from plants whose leaves formed depressions that retained rain
