nIn this fifth book in the Wow! series, youll discover the wonderful world of monkeys and apes. For nature lovers ages 5 years and up. nn Of all the animals, apes are closest to humans. Thats because apes, monkeys, and people are all primates. Like their human cousins, apes are very smart. They use tools, find solutions to problems, and even laugh and cry with their family and friends! Because apes are so much like humans, this book also teaches us a lot about ourselves.
