1. The ‘parasite-mediated sexual selection’ (PMSS) hypothesis predicts that exaggerated male ornamentation could provide a signal to females of a male’s ability to resist parasites. Empirical tests of the PMSS have been largely equivocal, however, which may be because most have not considered the role of early life-history effects. 2. Many sexually selected traits are carotenoid-based. Allocati...

The Cro-Magnon rock-shelter hosted the first discovered and certainly one of most important Gravettian burial sites in Europe. However, copious ornament collection found among human skeletons was not analysed with modern techniques. After proposing a synthesis complex curatorial history material, we submitted large proportion personal ornaments at site, five conservation institutions, to taxono...

Catholic church architecture is part of the development architecture, especially in Europe. The rationalism and density iconic buildings Europe raise allegation that during modern movement was not found but appeared missionary areas, including Indonesia. Queen Wilhelmina adopted ethical policy 1901 a driving factor for emergence modern-style Indonesia, building. Symbols ornaments are Church; th...

BACKGROUND Many animals display colorful signals in their integument which convey information about the quality of their bearer. Theoretically, these ornaments incur differential production and/or maintenance costs that enforce their honesty. However, the proximate mechanisms of production costs are poorly understood and contentious in cases of non-carotenoid-based plumage ornaments like the me...

Why females assess ornaments when choosing mates remains a central question in evolutionary biology. We hypothesize that the imperative for a choosing female to find a mate with nuclear oxidative phosphorylation (OXPHOS) genes that are compatible with her mitochondrial OXPHOS genes drives the evolution of ornaments. Indicator traits are proposed to signal the efficiency of OXPHOS function thus ...

The transition from the Middle Paleolithic (MP) to Upper Paleolithic (UP) is marked by the replacement of late Neandertals by modern humans in Europe between 50,000 and 40,000 y ago. Châtelperronian (CP) artifact assemblages found in central France and northern Spain date to this time period. So far, it is the only such assemblage type that has yielded Neandertal remains directly associated wit...
