“…The early history of the human-dog relationship is probably best exemplified by how humans treated their dogs in death. Single dog burials have been excavated at hunter-gatherer sites at least ~10,000 years ago in the Americas [10], East Asia [11], the Near East [12] and in Europe [13]. The earliest human-dog co-burials date to 14,200 years ago [14], and there are numerous examples across Eurasia and the Americas reflecting the importance of the human-dog relationship.…”

Simple Summary: The Earth is under increasing pressure from the burgeoning global human population and the subsequent rise in demand for food and a myriad of other finite resources. Mitigating the environmental, societal and ecological impact of the human footprint requires understanding the long-term relationships between our species and the plants and animals we now rely upon. In addition, the modern scientific approach often conceives of, and addresses individual problems through narrow windows that can fail to take into account the connectedness of multiple problems. By broadening the scope of inquiry to include both science and humanities perspectives, and simultaneously focussing on a single species, we suggest that many of the United Nations Strategic Development Goals (SDGs) can be addressed more effectively. In this paper, we describe Animals 2020, 10, 502 2 of 18 how a comprehensive assessment of the long-term relationship between humans and dogs can yield insights, and offer ways in which modern global challenges can be tackled. Abstract:No other animal has a closer mutualistic relationship with humans than the dog (Canis familiaris). Domesticated from the Eurasian grey wolf (Canis lupus), dogs have evolved alongside humans over millennia in a relationship that has transformed dogs and the environments in which humans and dogs have co-inhabited. The story of the dog is the story of recent humanity, in all its biological and cultural complexity. By exploring human-dog-environment interactions throughout time and space, it is possible not only to understand vital elements of global history, but also to critically assess our present-day relationship with the natural world, and to begin to mitigate future global challenges. In this paper, co-authored by researchers from across the natural and social sciences, arts and humanities, we argue that a dog-centric approach provides a new model for future academic enquiry and engagement with both the public and the global environmental agenda.

“…Although recent claims for the existence of so-called “Palaeolithic dogs” 2–5 as early as 30,000 years ago remain controversial 6,7 , there is incontrovertible evidence for the existence of domestic dogs in pre-farming hunter-gatherer societies in Europe at least 15,000 years ago, the Far East 12,500, and the Americas 10,000 years ago 8–10 .…”

Evidence of large genetic influences on dog ownership in the Swedish Twin Registry has implications for understanding domestication and health associations

Dogs were the first domesticated animal and, according to the archaeological evidence, have had a close relationship with humans for at least 15,000 years. Today, dogs are common pets in our society and have been linked to increased well-being and improved health outcomes in their owners. A dog in the family during childhood is associated with ownership in adult life. The underlying factors behind this association could be related to experiences or to genetic influences. We aimed to investigate the heritability of dog ownership in a large twin sample including all twins in the Swedish Twin Registry born between 1926 and 1996 and alive in 2006. Information about dog ownership was available from 2001 to 2016 from national dog registers. The final data set included 85,542 twins from 50,507 twin pairs with known zygosity, where information on both twins were available in 35,035 pairs. Structural equation modeling was performed to estimate additive genetic effects (the heritability), common/shared environmental, and unique/non-shared environmental effects. We found that additive genetic factors largely contributed to dog ownership, with heritability estimated at 57% for females and 51% for males. An effect of shared environmental factors was only observed in early adulthood. In conclusion, we show a strong genetic contribution to dog ownership in adulthood in a large twin study. We see two main implications of this finding: (1) genetic variation may have contributed to our ability to domesticate dogs and other animals and (2) potential pleiotropic effects of genetic variation affecting dog ownership should be considered in studies examining health impacts of dog ownership.

“…These analyses of dog bone may also include radiocarbon assays to determine the chronological placements of the dog remains under study or more broadly of features and layers within the particular sites where the dog bones were found. Dog bone may also be radiocarbon dated when used for other analyses such as ancient DNA (e.g., Perri et al., 2019).…”

Freshwater reservoir offsets on radiocarbon-dated dog bone from the headwaters of the St. Lawrence River, USA

Isotopic analysis of dog (Canis lupus familiaris) bone recovered from archaeological sites as proxies for human bone is becoming common in North America. Chronological placement of the dogs is often determined through radiocarbon dating of dog bone. The Great Lakes, their tributaries, and nearby lakes and streams were important fisheries for Native Americans prior to and after sustained European presence in the region. Carbon entering the food web in freshwater systems is often not in full isotopic equilibrium with the atmosphere, giving rise to spuriously old radiocarbon ages in fish, other aquatic organisms, and their consumers. These freshwater reservoir offsets (FROs) have been noted on human and dog bone in several areas of the world. Here we report the results of multi-tracer Bayesian dietary modeling using δ15N and δ13C values on dog bone collagen from mid-fifteenth to mid-sixteenth-century Iroquoian village sites at the headwaters of the St. Lawrence River, New York, USA. Results indicate that fish was an important component of dog diets. A comparison of radiocarbon dates on dog bone with dates on deer bone or maize from the same sites indicate FROs ranging from 97 ± 24 to 220 ± 39 14Cyr with a weighted mean of 132 ± 8 14Cyr. These results suggest that dog bone should not be used for radiocarbon dating in the absence of modeling to determine fish consumption and that previously reported radiocarbon dates on human bone from the larger region are likely to have FROs given the known importance of fish in regional human diets.
