Detailed explanation-1: -The correct answer is b. have the capacity to communicate meaning through symbols or gestures. Apes, notably gorillas, bonobos, and chimpanzees, can use symbols or gestures. They can learn from humans, but lack the vocal equipment to pronounce many human sounds.
Detailed explanation-2: -Thus, ape language research provided strong support for the gestural theory of language by demonstrating that apes could communicate symbolically with visual rather than auditory communication systems.
Detailed explanation-3: -The brain areas responsible for word meaning and grammar must mature and connections need to develop and strengthen. This process starts unconsciously and in every language a baby can be born into – in contrast to apes. Although these animals show complex capabilities, they are not able to acquire language.
Detailed explanation-4: -In these data, bonobos produced a total of 375 signals: 78.4% gestures, 13.8% facial/vocal signals, and 7.8% combinations of the two. Chimpanzees produced 383 signals: 55.9% gestures, 22.5% facial/vocal signals, and 21.6% combinations of the two.
Detailed explanation-5: -Most primates spend their lives in complex, tightly woven societies and need to frequently communicate with each other. They communicate with smells, sounds, visual messages, and touching. Non-human primates emphasize the use of body language.
