“…A set of sliding semilandmarks were then positioned along the marginal and oblique/transversal crests (82 semilandmarks on the UM3 and 72 semilandmarks on the P3 and P4; see Pan et al, 2016). In addition, a recently developed landmark-free approach was applied to compare the EDJ conformation (for its application to cercopithecoid molars, see Beaudet et al, 2016). This method relies on the construction of group-average surface models and their deformation to the investigated surfaces (Durrleman et al, 2012a, Durrleman et al, 2012b, Dumoncel et al, 2014.…”

Locality 1, in the Lower Cave of the Zhoukoudian cave complex, China, is one of the most important Middle Pleistocene paleoanthropological and archaeological sites worldwide, with the remains of c. 45 Homo erectus individuals, 98 mammalian taxa, and thousands of lithic tools recovered. Most of the material collected before World War II was lost. However, besides two postcranial elements rediscovered in China in 1951, four human permanent teeth from the 'Dragon Bone Hill,' collected by O. Zdansky between 1921 and 1923, were at the time brought to the Paleontological Institute of Uppsala University, Sweden, where they are still stored. This small sample consists of an upper canine (PMU 25719), an upper third molar (PMU M3550), a lower third premolar crown (PMU M3549), and a lower fourth premolar (PMU M3887). Some researchers have noted the existence of morpho-dimensional differences between the Zhoukoudian and the H. erectus dental assemblage from Sangiran, Java. However, compared to its chrono-geographical distribution, the Early to Middle Pleistocene dental material currently forming the Chinese-Indonesian H. erectus hypodigm is quantitatively meager and still poorly characterized for the extent of its endostructural variation. We used micro-focus X-ray tomography techniques of virtual imaging coupled with geometric morphometrics for comparatively investigating the endostructural conformation (tissue proportions, enamel thickness distribution, enamel-dentine junction morphology, pulp cavity shape) of the four specimens stored in Uppsala, all previously reported for their outer features. The results suggest the existence of time-related differences between continental and insular Southeast Asian dental assemblages, the Middle Pleistocene Chinese teeth apparently retaining an inner signature closer to the likely primitive condition represented by the Early Pleistocene remains from Java, while the Indonesian stock evolved toward tooth structural simplification.

“…The extensive genetic and physical mapping data made it possible for molecular cloning studies to be focused on a small segment of DNA on chromosome 7 (12,13,17,21,22). A putative CF gene has now been identified through chromosome walking and jumping (23) and cDNA clones have been isolated and characterized (24).…”

Genet. 205, 260 (1986)]; COX, human cytochrome c oxidase polypeptide III [S. Anderson et al., Nature 290, 457 (1981)]; NaCh, rat brain sodium channel III (32); raf, the serine-threonine kinase proto-oncogene of Xenopus laevis (31). The first two sequences are within membrane spanning segments and probably reflect only coincidental arrangements of the hydrophobic residues suited to this function. In contrast, the latter two sequences are both in polar hydrophilic regions of the proteins. The large extent of amino acid conservation (11 of 13 residues) implies some functional relation between these short segments of the primary structure of the Na' channel and CFTR. Similarities between sequences at the same relative locations with respect to the COOH-termini of the raf kinase and CFTR suggest that they may also share at least a small facet of their structures and functions.
