Basic principle and scope of ethnobotany biology discussion
Answers
Ethno botanical knowledge is very ancient. It provides information regarding the traditional uses of plant wealth which can be utilized in integrated tribal development.
The ethno botanical studies throw light on certain unknown useful plants and new uses of many known plants which can be exploited for developing new sources for some plant products and agro based industries.
The term ethno botany was coined by J.W. Harshberger in 1895 to include the study of plants used by the primitive and aboriginal people. Though this discipline has existed for ages, ethno botany emerged as a distinct academic branch of natural science in twentieth century.
According to the Principle of Scope, the semantic distance of grammatical and lexical modifiers relative to the head in the underlying structure is iconically reflected in the actual linguistic expression. Modifiers tend to occur next to the part of the expression that they have in their scope. This principle predicts — implicitly — that constituents that are in the scope of a certain modifier (that is, elements that are part of the same layer in the underlying noun phrase structure) are expressed in a continuous sequence. It also predicts — explicitly — that operators and satellites occur immediately before or after the material they have in their scope. This chapter discusses the relative order of modifiers in non-complex noun phrases and the position of embedded modifiers, along with free nominal aspect markers and adjectives. It also examines the relative order of demonstrative, numeral, adjective, and noun in those languages in which the three modifiers are always free, fully integrated constituents of the noun phrase.
