IntelligenceChimpanzees make tools and use them to acquire foods and they have sophisticated hunting strategies requiring cooperation, they are status conscious,manipulative and
they can learn to use symbols and understand aspects of human language including some relational syntax,concepts of number an[14] and they are capable of spontaneous planning for a future state or event.[15]Tool useOne of the most significant discoveries was in October 1960 when Jane Goodall observed the use of tools among chimpanzees.Recent research indicates that chimpanzee stone tool use dates to at least 4,300 years ago.[16] Chimpanzee tool usage includes digging into termite mounds with a large stick tool,and then using a small stick that has been altered to "fish" the termites out.[17] A recent study revealed the use of such advanced tools as spears,with which Common Chimpanzees in Senegal sharpen with their teeth and use to spear Senegal Bushbabies out of small holes in trees.[18][19] Before the discovery of tool use in chimps,it was believed that humans were the only species to make and use tools,but several other tool-using species are now known.[20][21]Studies of language Side profile of a ChimpanzeeScientists have long been fascinated with the studies of language,believing it to be a unique human cognitive ability.To test this hypothesis,scientists have attempted to teach human language to several species of great apes.One early attempt by Allen and Beatrice Gardner in the 1960s involved spending 51 months teaching American Sign Language to a chimpanzee named Washoe.The Gardners reported that Washoe learned 151 signs,and that she had spontaneously taught them to other chimpanzees.[27] Over a longer period of time,Washoe learned over 800 signs.[28]There is ongoing debate among some scientists,notably Noam Chomsky and David Premack,about non-human great apes' ability to learn language.Since the early reports on Washoe,numerous other studies have been conducted with varying levels of success,[29] including one involving a chimpanzee named,in parody,Nim Chimpsky,trained by Herbert Terrace of Columbia University.Although his initial reports were quite positive,in November 1979,Terrace and his team re-evaluated the videotapes of Nim with his trainers,analyzing them frame by frame for signs as well as for exact context (what was happening both before and after Nim’s signs).In the re-analysis,Terrace concluded that Nim’s utterances could be explained merely as prompting on the part of the experimenters,as well as mistakes in reporting the data.“Much of the apes’ behavior is pure drill,” he said.“Language still stands as an important definition of the human species.” In this reversal,Terrace now argued that Nim’s use of ASL was not like human language acquisition.Nim never initiated conversations himself,rarely introduced new words,and simply imitated what the humans did.Nim’s sentences also did not grow in length,unlike human children whose vocabulary and sentence length show a strong positive correlation儿童玩具琴/小电子琴5030智力动物琴26个英文字母发音琴

The Snow Leopard (雪豹） is a large cat native to the mountain ranges of central and southern Asia.Well known for its beautiful fur,the Snow Leopard has a soft grey coat with ringed spots and small dots of black on brown.The fur turns white in the winter.Because their fur command a very high price in the fur market,during the 1960s,the Snow Leopard's total population went down to 1,000 animals,but has since recovered slightly.The total estimated wild population of the Snow Leopard is between 3,500 and 7,000 individuals (see table below).In addition,there are 600-700 animals in zoos around theworld.The Sea otter (海獭) is a large otter native to the North Pacific.Sea otters have been hunted extensively for their luxurious fur.From 1741 onwards,over-hunting reduced sea otter populations to the point of extermination in many parts of their historic range.It is estimated that a half million to a million otters were killed over time.By 1911 the world population was estimated to be just 1,000-2,000 individuals in 13 colonies.Although several subspecies are still endangered,the otters have since been legally protected.}
