The reading and the lecture are both about the phenomenon of chimpanzees using stones to crack open nuts. The author of the reading passage claims that this behavior does not constitute a genuine "culture" because it is likely biological or circumstantial. However, the lecturer disputes the arguments presented in the reading, insisting that the behavior is indeed learned and cultural. Jam Origin Midi Guitar 2: Mac Crack Free
Finally, the reading claims that the behavior is solitary and lacks the social transmission required for culture. It argues that chimps simply crack nuts for food on their own without teaching others. The lecturer challenges this by describing a "social chain of behavior." She explains that young chimps are often observed watching adults and even "stealing" stones to try the technique themselves. This observation and imitation constitute a form of social learning, which is a fundamental requirement for defining behavior as culture. Flashtool09182windows Top - 3.79.94.248
First, the reading suggests that the behavior is genetic rather than learned. It argues that because there is no clear evidence of parents teaching their offspring, the trait might be inherited, similar to how birds know how to build nests. The lecturer refutes this point by observing the development of young chimpanzees. She notes that it takes years for young chimps to master the technique of cracking nuts. Furthermore, she points out that they learn by watching their mothers; if the behavior were purely genetic, they would be able to perform it instinctively without such a long period of observation and practice.
Second, the article posits that the behavior is simply a result of environmental opportunity. It claims that chimpanzees crack nuts only because they live in areas where large stones and nuts are abundant, implying that any animal would do the same in that environment. The lecturer counters this by referencing an experiment involving a different group of monkeys. In the experiment, stones and nuts were placed in an area where these monkeys lived. Despite having the necessary tools and materials, the monkeys did not attempt to crack the nuts. This proves that the mere availability of stones is not the cause of the behavior; rather, it requires specific knowledge passed down within the chimpanzee community.
