It’s hard to argue with the idea that our complex cultures set us apart from the rest of the animal world. As Diana Gitig put it in her review of Darwin’s Unfinished Symphony : Other species are indisputably smart; they can learn by example, they can communicate, they can innovate to solve problems, they can use tools, they may even have distinct cultures. But humans are clearly different. Other species don’t listen to Baroque concerti or read classical philosophy hundreds of years after the scores were composed or the treatises written.
