When a South African botanist Lyall Watson claimed in 1973 that plants had emotions that could be recorded on a lie detector test, he was dismissed by many in the scientific community.
However, new research, published in the journal Trends in Plant Science, has revealed that plants not only respond to sound, but they also communicate to each other by making "clicking" sounds. Using powerful loudspeakers, researchers at The University of Western Australia were able to hear clicking sounds coming from the roots of corn saplings. |  |
