<p>In recent years the relationship between language change and biological evolution has captured the attention of investigators operating in different disciplines, particularly evolutionary biology, AI and A-Life (Zeimke 2001, Hull 2001), as well as linguistics (Croft 2000; Sinha 1999), with each group often bringing radically different conceptualizations of the object under study, namely, “language” itself, to the debate. Over the centuries, meanings associated with the expression “language” have been influenced by mappings of conceptual frames and inputs from the biological sciences onto the entity referred to as “language”. At the same time the prestige of the “science of linguistics” created a feedback mechanism by which the referentiality of “language”, at each stage, was mapped back into the field of evolutionary biology along with the emergent structure(s) of the resulting “blend”. While significant energy has been spent on identifying ways in which biological evolution has been linked to concepts of language evolution (Dörries 2002), little attention has been directed to the nature of the conceptual integration networks that have been produced in the process. This paper examines the way conceptual integration theory can be brought to bear on the “blends” that have been created, focusing primarily on examples drawn from 19th century debates concerning the “language-species-organism analogy” in the emerging field of comparative-historical philology.</p><p>In recent years the relationship between language change and biological evolution has captured the attention of investigators operating in different disciplines, particularly evolutionary biology, AI and A-Life (Zeimke 2001, Hull 2001), as well as linguistics (Croft 2000; Sinha 1999), with each group often bringing radically different conceptualizations of the object under study, namely, “language” itself, to the debate.
