The central problem is still evolutionary stability.

- Abstract
We applaud Heintz & Scott-Phillips's guiding metaphor of "unleashing leashed expression," and we value the unified explanation for the emergence of not only language, but also other forms of unleashed expression, such as multimodal communication. We are more critical of the authors' discussion of the selection pressures acting towards unleashed expression, which are proposed to hinge on partner choice ecology.
