Getting a letter from the emperor saying that he's visiting is plot.
Having your apartment eaten by a wrecking ball...
...is something else entirely."
--Dr. Jules Hilbert in Stranger than Fiction
Juan described an analogy between living organisms and minerals. He proposed an idea of the gradual evolution of human beings, thereby anticipating Darwin's theory of evolution. In an 1815 work on nature's three kingdoms (mineral, vegetable and animal) he describes the Creator's plan for a continuous seamless chain of life from mineral life to vegetable life to animal life with no discrete discontinuous steps. Crystalline minerals tend to gather together in preparation for the higher form of vegetable life which then evolve into animal life. John showed unusual insight as well as care to maintain the scientific method, basing his claims on scientific observations. Called a heretic by some observers, he was ordered by the Archbishop of Bologna to hand over his findings to a committee of 18 theologians. The latter found no difficulty with John's work and approved publication. (Source)
