Group selection for adaptation to multiple-hen cages: beak-related mortality, feathering, and body weight responses.
The hypothesis was tested that selection on the basis of family means for increased survival and hen-housed egg production, when sisters with intact beaks were kept together in multiple-bird cage, would cause adaptive changes in behavior. Specifically, it was posited that beak-inflicted injuries causing cannibalistic mortality and feather loss and damage would be reduced. Body weight effects we...
متن کاملGroup Selection as Behavioral Adaptation to Systematic Risk
Despite many compelling applications in economics, sociobiology, and evolutionary psychology, group selection is still one of the most hotly contested ideas in evolutionary biology. Here we propose a simple evolutionary model of behavior and show that what appears to be group selection may, in fact, simply be the consequence of natural selection occurring in stochastic environments with reprodu...
متن کاملGroup Behavior: Social Context Modulates Behavioral Responses to Sensory Stimuli
A new study reveals an unanticipated role for social context in driving group behavior of a solitary species to a sensory stimulus and is mediated by mechanosensory neurons signaling touch interactions among individuals.
متن کاملBehavioral Data, Cultural Group Selection, and Genetics
Kasser et al. pose an important and often unad-dressed question: how do different institutional forms, or economic systems, shape the ideas, values, beliefs, motivations, and practices of their members or participants .(also see Bowles, 1998). While I applaud their 25 efforts in opening up this line, I offer two concerns. First, Kasser et al. neglected two large-scale comparative projects that ...
متن کاملFurnished cage system and hen well-being: Comparative effects of furnished cages and battery cages on behavioral exhibitions in White Leghorn chickens.
The battery cage system is being banned in the European Union before or by 2012, and the furnished cage system will be the only cage system allowed after 2012. This study was conducted to examine the different effects of caging systems, furnished cages vs. battery cages, on bird behaviors. One hundred ninety-two 1-d-old non-beak-trimmed Hy-Line W-36 White Leghorn chicks were reared using standa...
