Tresset [83]

Answer:

E. People once thought animals were individually create by some superior.

But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.

He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.
