Domestication has been consistently accompanied by a suite of traits called the domestication syndrome. These include increased docility, changes in coat coloration, prolonged juvenile behaviors, modified function of adrenal glands and reduced craniofacial dimensions. Wilkins et al recently proposed that the mechanistic factor underlying traits that encompass the domestication syndrome was alte...
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...
Human driven selection during domestication and subsequent breed formation has likely left detectable signatures within the genome of modern cattle. The elucidation of these signatures of selection is of interest from the perspective of evolutionary biology, and for identifying domestication-related genes that ultimately may help to further genetically improve this economically important animal...
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 ...
It has been hypothesized that reproductive isolation should facilitate evolution under domestication. However, a systematic comparison of reproductive barrier strength between crops and their progenitors has not been conducted to test this hypothesis. Here, we present a systematic survey of reproductive barriers between 32 economically important crop species and their progenitors to better unde...
Since the genome sequences of wild species may provide key information about the genetic elements involved in speciation and domestication, the undomesticated soybean (Glycine soja Sieb. and Zucc.), a wild relative of the current cultivated soybean (G. max), was sequenced. In contrast to the current hypothesis of soybean domestication, which holds that the current cultivated soybean was domesti...
The domestication of animals, plants, and microbes fundamentally transformed the lifestyle and demography of the human species [1]. Although the genetic and functional underpinnings of animal and plant domestication are well understood, little is known about microbe domestication [2-6]. Here, we systematically examined genome-wide sequence and functional variation between the domesticated fungu...
The aim of this paper is to survey the general area of quantitative trait locus (QTL) mapping, and its specific impact on current understanding of plant domestication. Plant domestication is not only of historical interest, but is also of ongoing importance as changing human needs and availability of nonrenewable resources impel continuing (and perhaps even accelerated) investigation of prospec...
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...
