Tim Requarth and Meehan Crist claim Jonah Lehrer's new book argues as much:

For years, scientists thought [humans] were different because we use tools. Not so, as it turned out. Chimpanzees have us there. And gorillas and orangutans and some other primates. And birds. And elephants. And a few bottlenose dolphins. Even ants use grain to carry honey. Until very recently, many scientists thought language set us apart, but in the past ten years, researchers have observed precursors to human speech in primate vocalizations and striking similarities between how infants learn to speak and songbirds learn to sing. Even self-awareness, a treasured feature of human consciousness, is no longer considered unique to humans.

It’s tempting to think that we are special, but today most researchers agree with Darwin’s eloquent observation that humans are animals, too; we are different in degree rather than kind. There’s no reason to think that creativity will be the exception.

The real problem is that claiming creativity’s exceptional status makes for a better story: if creativity is what sets us apart from the animals, understanding this faculty is tantamount to unlocking the mystery of who and what we are. As Lehrer writes, "Until we understand the set of mental events that give rise to new thoughts, we will never understand what makes us so special." This claim raises the stakes for the book. The problem is, it’s probably just not true.

Jonah counters from the comments section:

You … quibble with my speculation that human creativity is rather unique. Well, look around. We have remade this world of ours, for better or worse. We live fully surrounded by our own inventions. At the very least, this suggests that the human mind is doing something a little different than every other kind of mind.
