Domestication is an ongoing process continuously changing the lives of animals and humans and the environment. For the majority of European cattle (Bos taurus) genetic and archaeozoological evidence support initial domestication ca. 11'000 BP in the Near East from few founder aurochs (Bos primigenius) belonging to the mitochondrial DNA T macro-haplogroup. Gene flow between wild European aurochs...

Semantic symbols are essential components of Chinese characters. ShuoWenJieZi (Xyu Shen 121), the oldest dictionary of Chinese, is organized according to the radical forms as semantic symbols. Characters are classified according radicals, and their meanings cluster around the basic concept of the semantic symbol. We believe that ShuoWenJieZi radicals systemreflect conventional conceptualization...

Selection on intrinsic lifespan depends on both external factors affecting mortality and inherent tradeoffs in resource allocation between viability traits and other fitness-related traits. Longevity is therefore likely to vary between species in a sex-specific manner due to interspecific and intersexual differences in behavioural ecology. Here I focus on the bovid family to test two central hy...

The phenomenon of a remarkable conservation of the X chromosome in eutherian mammals has been first described by Susumu Ohno in 1964. A notable exception is the cetartiodactyl X chromosome, which varies widely in morphology and G-banding pattern between species. It is hypothesized that this sex chromosome has undergone multiple rearrangements that changed the centromere position and the order o...

The earliest known bovids, commonly placed in the genus Eotragus, are small species with short straight horns that are located above the orbits. Among living bovids there are several species that show a similar horn morphology. These dwarf antelopes were historically united in the group „Neotragini“, which is now known to be a polyphyletic assemblage. The species in the genera Ourebia, Raphicer...

The environmental contexts of the karstic hominin sites in South Africa have been established largely by means of faunal associations; taken together these data suggest a trend from relatively closed and more mesic to open, drier environments from about 3 to 1.5 Ma. Vrba argued for a major shift within this trend ca. 2.4-2.6 Ma, an influential proposal that posited links between bovid (and homi...

The fossil record provides tangible, historical evidence for the mode and operation of evolution across deep time. Striking patterns of convergence are some of the strongest examples of these operations, whereby, over time, similar environmental and/or behavioral pressures precipitate similarity in form and function between disparately related taxa. Here we present fossil evidence for an unexpe...

a r t i c l e i n f o The world's first archaeological traces from 2.6 million years ago (Ma) at Gona, in Ethiopia, include sharp-edged cutting tools and cut-marked animal bones, which indicate consumption of skeletal muscle by early hominin butchers. From that point, evidence of hominin meat-eating becomes increasingly more common throughout the Pleistocene archaeological record. Thus, the sub...
