Mosaic Evolution

Wikis > Glossary > Mosaic Evolution

Mosaic evolution is the predominant theory for the evolution of language that speculates that complex abilities like language or music possess distinct aspects that evolved separately from each other and at different times in evolutionary history. Evolution in a mosaic fashion suggests that component parts that make up a complex ability evolved for reasons other than that ability, and that they were then appropriated into the more complex ability over time. For instance, our vocal tract did not originally evolve for language, but it became a fundamental aspect of language once all the other component parts were in place (Bispham, 2008: 27).
