Evolution of True Carnivory
- True carnivory is believed to have evolved independently at least six times in flowering plants.
Historical Significance
- Charles Darwin published "Insectivorous Plants" in 1875, which recognized the ecological significance of carnivory in plants.
Classification of True Carnivory
- The classification of true carnivory encompasses approximately 600 species worldwide.
Carnivorous Plant Examples
- Notable examples include the Venus flytrap, pitcher plants, sundews, and butterworts.
Recognition of Carnivory
