Digest: A new tool will illuminate patterns of morphological integration.

Morphological integration is the result of natural selection influencing the evolution of multiple morphological traits simultaneously. Understanding how and why morphological traits covary is fundamental to uncovering the processes that drive phenotypic diversity. In a new study, Conaway and Adams (2022) review the utility of several methods for quantifying morphological integration and provide a new metric that will facilitate broad, novel comparisons of morphological integration among taxa and between different morphological features.
