Words painted on backdrops, words read to us with zest, words falling from the sky, words (and noises) streaming from the gleeful Children's Theatre of Charlotte audience. Books filling countless shelves, books that release cyclones when opened, books whose torn or trimmed pages can be turned into beards and lions' manes and even a scruffy little black dog named Toto.

The importance of FOXP2, and how it affects language.

People have a deep desire to communicate with animals, as is evident from the way they converse with their dogs, enjoy myths about talking animals or devote lifetimes to teaching chimpanzees how to speak. A delicate, if tiny, step has now been taken toward the real thing: the creation of a mouse with a human gene for language.

For decades, scientists thought perhaps smell was a diminished human sense and less valuable than other senses - like our glorious eyesight. "In the West, people came to this conclusion [through] the fact that we don't seem to have a good ability to talk about smells," says Asifa Majid, a professor of language and cultural cognition at Radboud University in the Netherlands. But Majid found that isn't universally true. Certain language speakers can name odors as easily as English speakers name colors, and the key difference may be how they live. Majid worked with speakers of four different languages: English and three from the Malay Peninsula. Two of these languages, Semaq Beri and Jahai, are spoken by hunter-gatherer groups. The other one, Semelai, is spoken by farmers. In order to test the ability of these language speakers to classify odors, Majid and her colleagues gave asked them to smell pen-shaped contraptions each filled with a different scent like leather, orange, garlic or fish - and then asked them to identify the smell. She also asked the participants to identify colors using different color chips. The farmer Semelai, like English speakers, found colors relatively easy to name and agreed with one another that the red chips were, indeed, red. When it came to identifying odors, the Semelai failed as miserably as the English speakers on the same tests. But both hunter-gatherer groups were much better at naming smells than the Semelai. In fact, they were just as good at identifying smells as colors. "That says something about the hunter-gatherer lifestyle," Majid says. There's a scarcity of English words that objectively describe odors, Majid says. Given that, readers of this article - written in English - may wonder how it's possible to describe a smell without leaning on other senses like taste (words like "sweet" or "sour") or emotional words like "gross." In English, most of our attempts to describe smells come from individual sources. You

Primates, birds, cetaceans, dogs and other species have proven able, through extensive training, to understand human words and simple sentences. And as Ed Yong explained, in some exceptional cases, such as Kanzi and Alex, they've even been able to engage in two-way communication with humans. However, language is more than a process through which meaning is attached to words or short sentences. Language might be described as the ability to take a finite set of elements (such as words), and using a set of rules (grammar and syntax) to create infinite combinations, each of which is comprehensible. In addition, as far as we can tell, humans are the only species who can create and comprehend understandable silliness, like "Colourless green ideas sleep furiously".

Tetsuro Matsuzawa, a Japanese primatologist, has spent 30 years studying our closest primate relative, the chimpanzee, to better understand the human mind. Here are some key takeaways: -Captive chimps can learn sign language or other communication techniques. They also can string together the symbols or gestures for words in simple "Me Tarzan, You Jane" combinations. -The animals use pant-hoots, grunts and screams to communicate. -In decades of ape language experiments, the chimpanzees have never demonstrated a human's innate ability to learn massive vocabularies, embed one thought within another or follow a set of untaught rules called grammar. So yes, chimpanzees can learn words. But so can dogs, parrots, dolphins and even sea lions. Words do not language make. Chimpanzees may well routinely master more words and phrases than other species, but a 3-year-old human has far more complex and sophisticated communication skills than a chimpanzee. "I do not say chimpanzees have language," Matsuzawa stresses. "They have language-like skills." -Monkeys can learn to use tools and do utilize tools, but there doesn't seem to be signs of them "teaching" each other these skills: it's more of a watch, then do situation.
