Journal ArticleDOI
Evolution and molecular mechanisms of adaptive developmental plasticity.
TL;DR: This work focuses on recent advances and examples from morphological traits in animals to provide a broad overview of the evolution of developmental plasticity, as well as its relevance to adaptive evolution.
Journal ArticleDOI
The Illogical Basis of Phylogenetic Nomenclature
TL;DR: The role of natural kinds in scientific practice and the nature of definitions and scientific classifications is reviewed, and current views on natural kinds and their definitions under a scientific realist perspective provide grounds for rejecting the class versus individual dichotomy altogether.
Journal ArticleDOI
A Phylogenetic Analysis of Ant Morphology (Hymenoptera: Formicidae) with Special Reference to the Poneromorph Subfamilies
TL;DR: In this paper, a synthesis of the external skeletal morphology of ants with special emphasis on the poneromorph subfamilies (Amblyoponinae, Ectatomminae, Heteroponerinae and Proceratiinae) is presented.
Journal ArticleDOI
Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors
TL;DR: The results reveal that ants invest in the relative size of thorax segments according to their tasks, revealing versatility of head movements allows for better manipulation of food and objects, which arguably contributed to the ants’ ecological and evolutionary success.
Journal ArticleDOI
Evolutionary history of the recruitment of conserved developmental genes in association to the formation and diversification of a novel trait

TL;DR: The evolutionary history of gene (co-)recruitment is consistent with both divergence from a recruited putative ancestral network, and with independent co-option of individual genes, which underscores the importance of widening the representation of phylogenetic, morphological, and genetic diversity.
