This study reports how university students domesticate their personal laptops at the beginning of studies on a wireless campus. The aim was to examine how students integrate the laptop into their personal education experience, what sort of processes were experienced to render the laptop useful and meaningful, and how gender and IT proficiency influenced this process. Qualitative interview data ...
The domestication of plants and animals marks one of the most significant transitions in human, and indeed global, history. Traditionally, study of the domestication process was the exclusive domain of archaeologists and agricultural scientists; today it is an increasingly multidisciplinary enterprise that has come to involve the skills of evolutionary biologists and geneticists. Although the a...
Recent increases in archaeobotanical evidence offer insights into the processes of plant domestication and agricultural origins, which evolved in parallel in several world regions. Many different crop species underwent convergent evolution and acquired domestication syndrome traits. For a growing number of seed crop species, these traits can be quantified by proxy from archaeological evidence, ...
Considerable insights were recently gained into the history and process of rice domestication. It becomes increasingly clear that artificial and natural selections coupled with extensive introgression have shaped the genomes of cultivated rice. The interplay of these evolutionary forces gave rise to the cultivated species, Oryza sativa, with divergent genomic backgrounds from two wild species, ...
Phenotypic variation has been manipulated by humans during crop domestication, which occurred primarily between 3000 and 10000 years ago in the various centers of origin around the world. The process of domestication has profound consequences on crops, where the domesticate has moderately reduced genetic diversity relative to the wild ancestor across the genome, and severely reduced diversity f...
Yak whole-genome resequencing reveals domestication signatures and prehistoric population expansions
Yak domestication represents an important episode in the early human occupation of the high-altitude Qinghai-Tibet Plateau (QTP). The precise timing of domestication is debated and little is known about the underlying genetic changes that occurred during the process. Here we investigate genome variation of wild and domestic yaks. We detect signals of selection in 209 genes of domestic yaks, sev...
The origins of agriculture, 10 000 years ago, led to profound changes in the biology of plants exploited as grain crops, through the process of domestication. This special case of evolution under cultivation led to domesticated cereals and pulses requiring humans for their dispersal, but the accompanying mechanisms causing higher productivity in these plants remain unknown. The classical view o...
This article acknowledges the vital role that the Domestication Research-perspective has in media research, but criticizes it for being analytically ambiguous in its use of the central term ‘domestication’. By way of a contrastive set of data from an ongoing research project, we argue for a dislocation of ‘domestication’ from the domestic and the private. Instead, we wish to retain the meaning ...
The process of domestication involves adaptation, usually to a captive environment. Domestication is attained by some combination of genetic changes occurring over generations and Ž . developmental mechanisms e.g., physical maturation, learning triggered by recurring environmental events or management practices in captivity that influence specific biological traits. The transition from free-liv...
De-domestication is a unique evolutionary process by which domesticated crops are converted into 'wild predecessor like' forms. Weedy rice (Oryza sativa f. spontanea) is an excellent model to dissect the molecular processes underlying de-domestication. Here, we analyse the genomes of 155 weedy and 76 locally cultivated rice accessions from four representative regions in China that were sequence...
