生物语言学研究作为一种跨学科、多领域、综合性研究，主要关注人类语言的生物属性，涵盖生物学、语言学、人类学、考古学、解剖学、计算机科学、心理学等多个领域。其根源最早可以追溯到15世纪的文艺复兴时期达芬奇将语言看作人类的一种生物机能的假设。但是，在当时的认知和现实条件下，并没有也不可能给出一个专门的术语对这种假设进行描述。在达尔文之后的探索中，ClarenceL.Meader和JohnH.Muyske...
红古话是目前确知只有两个单字调的极少数汉语方言点之一。本文对4名发音人的声调进行声学实验分析，通过对音高曲线的考察和对音高数据的聚类分析，将红古话声调的调值处理为第一声（平去声）24；第二声（上声）53。
