Animals are more like us than you think: Jane Goodall's "Learning From Chimpanzees" exemplifies it.

Quote: "Of all the facts to emerge from my years of research on the chimpanzees at Gombe, it is their humanlike behaviors that most fascinate people: their tool-using and tool-making abilities; the close supportive bonds among family members, which can persist throughout a lifetime of 50 or more years; and their complex social interactions—the cooperation, the altruism, and the expression of emotions like joy and sadness." (Goodall)
