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.

Dr Katie Slocombe and Dr Anne Schel, of the Department of Psychology at York, examined the degree of intentionality wild chimpanzees have over their alarm calls. The study shows that chimpanzees appear to produce certain alarm calls intentionally in a tactical and goal directed way--they are not simply fear-based reactions. In Uganda, the researchers presented wild chimpanzees with a moving snake model and monitored their vocal and behavioural responses. They found that the chimpanzees were more likely to produce alarm calls when close friends arrived in the vicinity. They looked at and monitored group members both before and during the production of calls and critically, they continued to call until all group members were safe from the predator. Together these behaviours indicate the calls are produced intentionally to warn others of the danger. Dr Slocombe said: "These behaviours indicate that these alarm calls were produced intentionally to warn others of danger and thus the study shows a key similarity in the mechanisms involved in the production of chimpanzee vocalisations and human language. "Our results demonstrate that certain vocalisations of our closest living relatives qualify as intentional signals, in a directly comparable way to many great ape gestures, indicating that language may have originated from a multimodal vocal-gestural communication system."

In this article, scientist Wilkie Freud followed a group of chimpanzees around to learn more about the origin of language. The human lineage broke from chimpanzees roughly 7.9 million years ago. The study they found was that the chimpanzees use language when necessary, like when a snake is seen. They will shout an alarm call to warn other about the danger. They also seem to grunt when they enjoy food. This shows how chimpanzees and humans have similar but very different types of language.

Researchers at Georgia State University's Language Research Center examined how two language-trained chimpanzees communicated with a human experimenter to find food. Their results are the most compelling evidence to date that primates can use gestures to coordinate actions in pursuit of a specific goal. Dr. Charles Menzel, a senior research scientist, notes, "The chimpanzees used gestures to recruit the assistance of an otherwise uninformed person and to direct the person to hidden objects 10 or more meters away...the findings illustrate the high level of intentionality chimpanzees are capable of, including their use of directional gestures. This study adds to our understanding of how well chimpanzees can remember and communicate about their environment."

"Chimpanzees appear to consider who they are "talking to" before they call out. Researchers found that wild chimps that spotted a poisonous snake were more likely to make their "alert call" in the presence of a chimp that had not seen the threat. This indicates that the animals "understand the mindset" of others."

Psychologists who analyzed video footage of a female chimpanzee, a female bonobo and a female human infant in a study to compare different types of gestures at comparable stages of communicative development found remarkable similarities among the three species. Gestures made by all three species included reaching, pointing with fingers or the head, and raising the arms to ask to be picked up. The researchers called "striking" the finding that the gestures of all three species were "predominantly communicative," Greenfield said. To be classified as communicative, a gesture had to include eye contact with the conversational partner, be accompanied by vocalization (non-speech sounds) or include a visible behavioral effort to elicit a response. The same standard was used for all three species. For all three, gestures were usually accompanied by one or more behavioral signs of an intention to communicate. At the beginning stage of communication development, gesture was the primary mode of communication for human infant, baby chimpanzee and baby bonobo. The child progressed much more rapidly in the development of symbols. Words began to dominate her communication in the second half of the study, while the two apes continued to rely predominantly on gesture. "This was the first indication of a distinctive human pathway to language," Greenfield said. All three species increased their use of symbols, as opposed to gestures, as they grew older, but this change was far more pronounced for the human child. The child's transition from gesture to symbol could be a developmental model of the evolutionary pathway to human language and thus evidence for the "gestural origins of human language," Greenfield said. While gesture may be the first step in language evolution, the psychologists also found evidence that the evolutionary pathway from gesture to human language included the "co-evolution of gestural and vocal communication." Most of the child's gestures were accompanied b

A new study conducted by the University of Pennsylvania has shown that children as young as two understand basic grammar rules when they first learn to speak and are not simply imitating adults. The study also applied the same statistical analysis on data from one of the most famous animal language-acquisition experiments -- Project Nim -- and showed that Nim Chimpsky, a chimpanzee who was taught sign language over the course of many years, never grasped rules like those in a two-year-old's grammar. "When you compare what children should say if they follow grammar against what children do say, you find it to almost indistinguishable," Professor of Linguistics Charles Yang said. "If you simulate the expected diversity when a child is only repeating what adults say, it produces a diversity much lower than what children actually say." As a comparison, Yang applied the same predictive models to the set of Nim Chimpsky's signed phrases, the only data set of spontaneous animal language usage publicly available. He found further evidence for what many scientists, including Nim's own trainers, have contended about Nim: that the sequences of signs Nim put together did not follow from rules like those in human language. Nim's signs show significantly lower diversity than what is expected under a systematic grammar and were similar to the level expected with memorization. This suggests that true language learning is -- so far -- a uniquely human trait, and that it is present very early in development.

There are many laws of linguistics that exist in human communication. Laws such as Zipf's law of abbreviation, which predicts commonly used words to be short, and Menzerath's law, which predicts that large linguistic structures are made of shorter ones. This article talks about a study conducted by a team of researchers from the University of Roehampton, which explores the parallels of these linguistic laws in chimpanzee gestural communication. They measured the length of over 2000 gestures, and found that they indeed used shorter gestures if they were using it more frequently and long gestures were composed of the shorter ones.

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.

Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, examines laughter as a means of exploring mechanisms and evolution of vocal production, perception and social behavior. He examines laugh structure, compares human to chimp laughter, sociolinguistic contexts of laughter, the contagiousness of laughter, and pinpoints directions for future study. This article, originally printed in American Scientist 84. 1 (Jan-Feb, 1996): 38-47, is a more in-depth, scholarly article than the other, related article on laughter that I posted: Provine's "The Science of Laughter."

New ways to grab dinner, the trick to using a tool, and learning the local dialect. These are behaviors that animals pick up from each other. K iller whales, chimpanzees, and birds seem to have a cultural component to their lives. Now a new study suggests that sperm whales should be added to that list.

The importance of FOXP2, and how it affects language.

Research has shown that primates can produce unique calls for things or events in their environment, such as the arrival of a predator or discovery of high-quality food. Scientists had assumed that referential calls were innate and rigid among nonhuman primates, and not flexible and socially learned as they are among Homo sapiens. Yet, a recent study suggests that primates may, in fact, be able to engage in social learning, acquiring and using another group's sounds.

Of the 20,000 genes in the human genome, few are more fascinating than FOXP2, a gene that underlies the faculty of human speech. All animals have an FOXP2 gene, but the human version's product differs at just 2 of its 740 units from that of chimpanzees, suggesting that this tiny evolutionary fix may hold the key to why people can speak and chimps cannot.
