“…Asymmetry of mammalian skulls is well known, see, e.g. [ 31 , 32 ]. Studies of asymmetry of human skulls have initially used length and angle measurements and lately the Procrustes analysis of landmarks, see, e.g.…”

“…For directional asymmetry we must look the explanation on the masticatory apparatus, as it would suggest a direct association to chewing mechanical factors. In vertebrates, these directionalities in left±right dimensions have been found [17][18][19][20][21]. A genetic background for the phenomenon has been suggested [22], although until recent years no specific genes have been found to cause the lateralized behaviour [23] Mastication is dominated by the masseter muscle and has its origin on the skull, where it is attached from the zygomatic bone until the facial tubercle [24].…”

“…Dicho de otro modo: una reducción del tamaño craneal no implicaría una versión reducida de la forma (una "reducción harmónica"), sino que se expresaría como un cambio heterotópico, cambios diferentes en cada punto de toda la estructura cefálica. Esta heterocronía, que produce diferencias en el desarrollo postanatal entre especies, ha sido ampliamente descrita en el cráneo (Cordeiro-Estrela et al, 2006;Cardini & Polly, 2013), asociándose claramente este cambio, en algunas ocasiones, a diferencias funcionales (Castillo et al, 2016). Este estudio taxonómico se basa en relativamente pocos ejemplares, y centrado únicamente en el plano dorsal craneal.…”
