In 1848, Charles Darwin began the quest to understand the mysteries of the animal mind. Following Darwin's achievement - suggesting a plausible process for evolution: natural selection - Lewis Henry Morgan discovered evidence of cogitation in beavers. George Romanes experimented with fish, cats, and dogs, Douglas Spalding with newborn chicks, all finding apparent mental activity. Meanwhile Jacques Loeb attempted to prove animals "mindless."
