Abstract Based on his analyses of lynx and brown bear teeth, Bjorn Kurten coined the concept of 'realisation threshold', the smallest size at which a tooth can form and erupt properly. Kurten found the smallest sizes of the studied lynx and bear teeth to be 2.5 mm and 3.5 mm, respectively, much larger than for example the smallest rodent teeth known to readily erupt.
Abstract Mammals have evolved a broad variety of dental morphologies. Nevertheless, the development of the mammalian dentition is considered highly conserved. Molar size proportions exemplify this as a system where small changes in shared developmental mechanisms yield a defined range of morphological outcomes. The Inhibitory Cascade (IC) model states that as molars develop in a sequence, the first developing anterior molars inhibit the development of subsequent posterior ones.
1 INTRODUCTION Two arterial systems supply the vertebrate brain. The anterior carotid system derives from the internal carotid artery and irrigates the forebrain. The posterior vertebral system derives from the vertebral arteries and mainly supplies the brainstem (Fenrich et al., 2021).
