dc.description.abstract |
Domestic animals are often described as paedomorphic, meaning that they
retain juvenile characteristics into adulthood. Through a three-dimensional
landmark-based geometric morphometric analysis of cranial morphology
at three growth stages, we demonstrate that wild boar (n ¼ 138) and domestic
pigs (n ¼ 106) (Sus scrofa) follow distinct ontogenetic trajectories.
With the exception of the size ratio between facial and neurocranial regions,
paedomorphism does not appear to be the primary pattern describing the
observed differences between wild and domestic pig cranial morphologies.
The cranial phenotype of domestic pigs instead involves developmental
innovation during domestication. This result questions the long-standing
assumption that domestic animal phenotypes are paedomorphic forms of
their wild counterparts. |
