DOI: 10.1007/s10071-020-01394-z
Abstract: Intra-species cognitive variation is commonly observed, but explanations for why individuals within a species differ in cognition are still understudied and not yet clear. Cognitive processes are likely influenced by genetic differences, with genes in… read more here.

DOI: 10.1007/s13353-018-0435-8
Abstract: During the domestication of farm animals, humans have manipulated genetic variation for growth and reproduction through artificial selection. Here, data are presented for growth, reproductive, and behavior traits for the red junglefowl, a line of… read more here.

DOI: 10.1038/s41598-021-81589-7
Abstract: In this study, we aimed to elucidate the origin of domestic chickens and their evolutionary history over the course of their domestication. We conducted a large-scale genetic study using mitochondrial DNA D-loop sequences and 28… read more here.

DOI: 10.1098/rsos.211002
Abstract: Domestication is the process by which wild organisms become adapted for human use. Many phenotypic changes are associated with animal domestication, including decreases in brain and brain region sizes. In contrast with this general pattern,… read more here.

DOI: 10.1371/journal.pone.0204303
Abstract: The domesticated phenotype is a set of behavioural, morphological and physiological traits that is common for domesticated species. Previous research has found that selection for tameness only can give rise to correlated selection responses that… read more here.

Effects of domestication on responses of chickens and red junglefowl to conspecific calls: A pilot study

DOI: 10.1371/journal.pone.0279553
Abstract: Beyond physical and zootechnical characteristics, the process of animal domestication has also altered how domesticated individuals, compared to their wild counterparts, perceive, process, and interact with their environment. Little is known, however, on whether and… read more here.

How Inhibitory Control Relates to Positive and Negative Affective States in Red Junglefowl
Sign Up to like & getrecommendations! Published in 2022 at "Frontiers in Veterinary Science"
DOI: 10.3389/fvets.2022.872487
Abstract: Individual differences in inhibitory control, an aspect of cognition, are found in many species. How this variation links to affective states is not much explored, and could be relevant for welfare. As less fearful, more… read more here.
