The gene theory holds that the greater the number of genes, the greater the evolutionary progress and survival potential. Scientists went on to work out that humans have 25,000 genes. Then they discovered that rice has 46,000 genes.
Given water, rice will survive forever.
Without doubt, humans are smarter than plants, so why is it that they are less survival developed?
The answer could be free will. Free will means that humans can go off on tangents. While on the one hand, those tangents lead to inventions and new ways of doing things – human advances. On the other hand, they can also lead to social engineering schemes so daft that they hinder the course of survival – human retardation, or even regression.
Plants have no such aberrant behaviour. All they care about is survival.
That is why rice, on current trajectory, will last long enough to feast on the soil, nutrient-rich from the decayed remains of the human race that once ate rice.
