Scientists have confirmed a theory proposed by Charles Darwin over 150 years ago. Darwin had suspected that certain plant species might be carnivorous due to their sticky hairs. He proposed that Saxifraga rotundifolia and S.

umbrosa were insectivorous plants, but was unable to prove it at the time. The plants' structures, called tricomas glandulares, secrete a sticky substance and resemble the hairs found on some carnivorous plants. To be considered carnivorous, a plant must attract, trap, and digest insects.

Further details on the confirmation of Darwin's theory are available from the source. For more information on this discovery, readers can refer to the original report from KVIA ABC-7's source.
