Human is no longer a special classification but merely an adjective describing our animal nature.
Twenty-five years earlier, in a much different type of chimpanzee research, Roger Fouts taught Booee sign language. That's what he's calling me. Far too many humans, however, refuse to acknowledge the importance of language development in nonhuman primates and the important affinity between great apes - including both humans and chimpanzees. In terms of biochemical similarities based on blood research and genetic similarities chimpanzees are actually closer to humans than they are to gorillas, even though all three primates are within one percent of each other. These same similarities cause one to consider whether humans have the right to enslave these innocent creatures for our own curiosity and potential scientific progress.
