Thanks to ongoing advances in space exploration and computer science, we may hope to encounter extraterrestrial life, or create sentient machines, within the not-too-distant future. Yet for all our searching for intelligence among the stars, or striving to create it in a laboratory, we often fail to realize that the Earth already teems with intelligent beings: other animals.<\/p>\n

After all, animals don’t reason, talk, or develop cultures or societies. Or do they? In recent decades, scientists have reconsidered many long-held assumptions about other animals, and discovered that many species are intelligent in ways never before thought possible.<\/p>\n
