1. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation
Sammanfattning : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. LÄS MER

3. Domestication effects on foraging behaviour : consequences for adaptability in chickens
Sammanfattning : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.

4. Older People Meet Robots : Three Case Studies on the Domestication of Robots in Everyday Life
Sammanfattning : This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. LÄS MER
5. Domestication of Brassica oleracea L
Sammanfattning : Various theories exist about the progenitors of B. oleracea L. (cole crops) and the area of its domestication. Relatively recent molecular data have pointed at the wild species growing on the European Atlantic cliffs as the closest relatives to all the cultivated types. LÄS MER
