abstract = {Despite large-scale molecular attempts, the relationships
of the basal winged insect lineages dragonflies, mayflies
and neopterans, are still unresolved. Other data sources,
such as morphology, suffer from unclear functional
dependencies of the structures considered, which might
mislead phylogenetic inference. Here, we assess this problem
by combining for the first time biomechanics with
phylogenetics using two advanced engineering techniques,
multibody dynamics analysis and finite-element analysis, to
objectively identify functional linkages in insect head
structures which have been used traditionally to argue basal
winged insect relationships. With a biomechanical model of
unprecedented detail, we are able to investigate the
mechanics of morphological characters under biologically
realistic load, i.e. biting. We show that a range of head
characters, mainly ridges, endoskeletal elements and joints,
are indeed mechanically linked to each other. An analysis of
character state correlation in a morphological data matrix
focused on head characters shows highly significant
correlation of these mechanically linked structures.
Phylogenetic tree reconstruction under different data
exclusion schemes based on the correlation analysis
unambiguously supports a sistergroup relationship of
dragonflies and mayflies. The combination of biomechanics
and phylogenetics as it is proposed here could be a
promising approach to assess functional dependencies in many
organisms to increase our understanding of phenotypic
evolution.},
