Abstract
Dogs have played an outsized role in the field of behavioral genetics since its earliest days. Their unique evolutionary history and ubiquity in the modern world make them a potentially powerful model system for discovering how genetic changes lead to changes in behavior. Genomic technology has supercharged this potential by enabling scientists to sequence the DNA of thousands of dogs and test for correlations with behavioral traits. However, fractures in the early history of animal behavior between biological and psychological subfields may be impeding progress. In addition, canine behavioral genetics has included almost exclusively dogs from modern breeds, who represent just a small fraction of all dog diversity. By expanding the scope of dog behavior studies, and incorporating an evolutionary perspective on canine behavioral genetics, we can move beyond associations to understanding the complex interactions between genes and environment that lead to dog behavior.
自行为遗传学诞生之初,狗就在这一领域发挥着举足轻重的作用。它们独特的进化历史和在现代世界中无处不在的特性,使它们成为发现基因变化如何导致行为变化的潜在强大模型系统。基因组技术使科学家们能够对成千上万只狗的 DNA 进行测序,并测试它们与行为特征之间的相关性,从而极大地增强了这一潜力。然而,早期动物行为学在生物学和心理学子领域之间的断裂可能阻碍了研究的进展。此外,犬类行为遗传学几乎只包括现代犬种,而现代犬种只占犬类多样性的一小部分。通过扩大犬类行为学的研究范围,并将进化论的视角纳入犬类行为遗传学,我们可以超越关联,理解基因与环境之间导致犬类行为的复杂相互作用。
期刊介绍:
The Annual Review of Animal Biosciences is primarily dedicated to the fields of biotechnology, genetics, genomics, and breeding, with a special focus on veterinary medicine. This includes veterinary pathobiology, infectious diseases and vaccine development, and conservation and zoo biology. The publication aims to address the needs of scientists studying both wild and domesticated animal species, veterinarians, conservation biologists, and geneticists.
