Morphological integration of the avian beak facilitates evolution along lines of least resistance

11,000 species, with vast morphological disparity suggesting limited developmental constraints on beak diversification. We assess four macroevolutionary currencies: integration, disparity, phenotypic evolutionary rates, and ecological specialization, using 3D beak landmarks for 8,627 species mapped to a complete avian supertree with a resolved genomic backbone. We introduce a Gini coefficient-based metric of ecological specialization, measuring evolutionary time spent across trophic niches. Phylogenetic regressions show that lineages with faster phenotypic rates exhibit stronger beak integration (landmark covariation) and more generalised diets, while beak disparity declines with greater trophic specialization. These results suggest that integration facilitates, rather than constrains, phenotypic evolution, by channeling variation along lines of least resistance. Future work should explore modular structure of the bird beak, which arises from multiple genetic and developmental factors.

77%) and loss of the typical quadripartite architecture. Despite the absence of the stabilizing inverted repeats, the Mitrastemon panplastome exhibits remarkable structural stability and collinearity among individuals. The reduced suite of 26 genes, which includes accD, infA, clpP, ycf1, ycf2, and the essential tetrapyrrole precursor trnE-UUC, exhibit elevated substitution rates. Evolutionary rate analyses (dN/dS) demonstrate that the core ribosomal suite remains under strong purifying selection ({omega}<1), confirming the organelles functional status. Furthermore, transcriptomic analysis identified a nearly complete set of nuclear-encoded DNA-RRR genes, with the notable exception of the MUTS2 surveillance system. The convergent loss of these homologs in Mitrastemon and another holoparasitic lineage may be linked to the shared structural instability and mutational bias. Our findings demonstrate that despite extreme genome compaction, accelerated substitution rates, and severe AT-bias, the Mitrastemon panplastome remains quite stable, providing a definitive genomic framework for understanding plastid evolution within the endoparasitic Mitrastemonaceae.
