Abstract/Description
-
Chimpanzees have long been documented as using population-specific vocalizations, implying learning rather than just genetics in chimpanzee calls. In order for population-specific vocalizations to arise, diachronic change, or evolution, of the various features of the vocalizations must occur. When a population is split, as they were in the current study, there are changes of social structure, environment, and emotional stress (all factors which can lead to rapid phonological change in humans)...
Show moreChimpanzees have long been documented as using population-specific vocalizations, implying learning rather than just genetics in chimpanzee calls. In order for population-specific vocalizations to arise, diachronic change, or evolution, of the various features of the vocalizations must occur. When a population is split, as they were in the current study, there are changes of social structure, environment, and emotional stress (all factors which can lead to rapid phonological change in humans). These factors can act as a catalyst for punctuated diachronic change. A vocal survey was performed on two groups of chimpanzees who had been separated from each other two years prior to the research. The results of the survey revealed significant differences between the two groups' vocalizations. These results make a case for diachronic change in chimpanzee vocalizations, the seed of population-specific calls.

Abstract/Description

There are certain properties of the human mind which allow abstract thought. These properties are responsible for the ability to create myth (or explanations of the unknown), cosmology, and culture. They are the seeds of all human phenomena not attributable to instinct. These properties can be isolated as the capacity for numeric logic and the mind functioning in terms of binary oppositions. The long held paradigm sees the human species as unique in possessing these qualities and well as the...
Show moreThere are certain properties of the human mind which allow abstract thought. These properties are responsible for the ability to create myth (or explanations of the unknown), cosmology, and culture. They are the seeds of all human phenomena not attributable to instinct. These properties can be isolated as the capacity for numeric logic and the mind functioning in terms of binary oppositions. The long held paradigm sees the human species as unique in possessing these qualities and well as the phenomena they yield. In order to challenge this paradigm, a two experiments are conducted on a chimpanzee to see if she possessed these properties. She successfully completed the cognitive tests on both experiments, thus implicating the human species as not unique in its abstractions.
