Plants are so unlike people that it’s very difficult for us to appreciate fully their complexity and sophistication. Yet plants have been evolving much, much longer than we have, have been inventing new strategies for survival and perfecting their designs for so long that to say that one of us is the more “advanced” really depends on how you define that term, on what “advances” you value. Naturally we value abilities such as consciousness, toolmaking, and language, if only because these have been the destinations of our own evolutionary journey thus far. Plants have traveled all that distance and then some—they’ve just traveled in a different direction.
