"The idea of plants having intelligence is a contradiction to our world view, but at the same time it is deeply consistent with our theory of evolution. All life is branched out from the once centre, rippling out, finding its own way to earn the right to live and pass on its genetic inheritance. What is true of animals is true of plants: there are superior plants endowed with greater capability for perception, memory and communication than others. In other words, with varying degrees of intelligent behaviour. If we ask, "who is superior, animal or plant?" than at least in Limpopo Savanna, the answer is clear. The threatened acacia tree kills the starving kudu. And what if we went a little further and associated survival with intelligence, and we ask who will be around the longest? Then, the answer could be a little disconcerting."
