Abstract
The cross-linguistic under-representation of adjacent consonants sharing a place of articulation within uninflected lexical items is well documented. At the same time, little is known regarding the specific diachronic mechanisms involved in the emergence and maintenance of this pattern. Phylogenetic analyses provide some support for the idea that adjacent identical consonants within words arise infrequently, but stronger support for the idea that words containing such a pattern die out more frequently than those without. I highlight the value of tools used in this paper for exploring the evolution of sound patterns, and also discuss some limitations of the implementation used in the paper to be improved upon.
